2.0 Introduction of the Project/Background Information

2.1 Identification of the Project and Project Proponent

Larsen & Toubro Limited (L&T) is a diversified Indian multinational conglomerate

with very sound technical and financial resources. During 2014-15, the

consolidated revenue was in excess of Rs. 92,000 Crores. It operates in over 30

countries worldwide. A strong, customer–focused approach and the constant

quest for top-class quality have enabled L&T to attain and sustain leadership in its

major lines of business for over seven decades.

L&T has proposed to set up an alumina refinery project in Odisha. Investment

decision is dependent on the captive source of sizeable reserves of bauxite. The

state government granted the prospecting licenses to L&T for Kutrumali and

Sijimali bauxite deposits. Both the deposits are nearby and are located in

Kalahandi and Rayagada districts. After successfully completing the prospecting

operations, L&T applied for mining leases. State government has recommended

the applications to central government for their approval for grant of mining

leases in accordance with law.

Out of total estimated mineable reserves of bauxite in these two deposits to the

tune of 249 million tonnes, Kutrumali deposit has got 47 million tonnes and the

balance 202 million tonnes are from Sijimali deposit.

The ultimate capacity of 3 MTPA of the proposed alumina refinery will require

bauxite of 9 MTPA, considering 3 tonnes of bauxite for 1 tonne of alumina. This

requirement will be met partly from Kutrumali (3 MTPA) and partly from Sijimali

(6 MTPA). This report is for mining of bauxite from Kutrumali deposits at a rate of

3 MTPA (peak). A separate report for mining of bauxite from Sijimali deposits has

been prepared.

L&T is known to be a reputed engineering conglomerate having highly qualified

engineers. L&T is a leading manufacturer of state of the art mining equipment and

a global engineering player in the field of metals and mining and therefore they

are in a pre-eminent position to conduct scientific and environment friendly

mining. The mining methods, amongst others, shall aim at minimising or

eliminating blasting operations. Extensive use of Surface Miners and/or IPCC (In

Pit Crushing and Conveying) shall be resorted to.

2.2 Brief Description of Nature of Project

The lease area of 696.734 hectares (1721.680 acre) falls under tehsil Thaumul–

Rampur of Kalahandi district and tehsils Kashipur & Rayagada of Rayagada district



in the state of Odisha. The lease area falls under the Survey of India toposheet

no. E44F3 and bounded by latitude of 19° 25’ 50.28” to 19° 29’ 6.12” N &

longitude of 83° 10’ 11.47” to 83° 13’ 7.87” E. The proposed lease area is having

about 47 million tonnes of mineable reserves.

The extracted bauxite will be used in the proposed 3 MTPA production capacity

alumina refinery in Rayagada district, Odisha. The mining lease shall be granted

for Bauxite mining for a period of 50 years. The proposed Bauxite mine shall be

developed by opencast mechanized mining method. The main operation shall

include removal and stocking of top soil by excavator cum loaders, exposing the

aluminous bauxite/bauxite zone and proper levelling by dozer and use of surface

miners. Bauxite will be then sorted out and reduced its size. The remaining rejects

will be used for backfilling.

Extent of Mechanization

The entire mining activity involves fragmentation/loosening of in-situ rock mass,

excavation, loading and hauling, sizing and subsequent handling/transportation

etc. These are envisaged to be carried out by employing equipment like rippers,

drills, excavators and loaders, rear dump trucks, crusher, feeders and belt

conveyors etc. the details of proposed extent of Mechanization are given in below

2.3 Need for the project and its importance to the country and region

Bauxite is basically an aluminous rock containing hydrated aluminium oxide as

the main constituent and iron oxide, silica and titania in varying proportions.

Hydrated aluminium oxides present in the bauxite ore are diaspore and

boehmite, Al2O3. H2O (Al2O3- 85%; Al- 45%); gibbsite or hydrargillite, Al2O3.

3H2O (Al2O3-65.4%; Al-34.6%), and bauxite (containing colloidal alumina

hydrogel), Al2O3. 2H2O (Al2O3-73.9%; Al-39.1%). Bauxite is an essential ore of

aluminium and is one of the most important nonferrous metals used in the

modern industry. It is also an essential ore for refractory and chemical

industries. The country has abundant resources of bauxite which can meet both

domestic and export demands.

The production of mineral and its subsequent use in the Alumina Refinery will

benefit by way of royalty and taxes and will also bring in large employment

opportunities to the local populace thereby usher in socio-economic benefit to

the backward region.

2.4 Demand and Supply Gap

The production of bauxite at 15,360 thousand tonnes in 2012-13 increased by

13% as compared to previous year, due to better market demand.

There were 152 reporting mines in 2012-13 as against 172 in the previous year.

Besides, production of bauxite was reported as associate mineral by 10 mines

during the year. In all, 70 producers reported production of bauxite in 2012-13.

Ten principal producers having 42 mines contributed 86% of the total

production. Forty seven major mines, each producing more than 50 thousand

tonnes per annum, together accounted for 93% of the total production. The

contribution of the Panchpatmali bauxite mine of NALCO was 35% of the total

production. The share of public sector mines was about 42% of the total

production in 2012-13 as against 43% in the previous year. About 63% of the

total production of bauxite was of 40-45% Al2O3 grade, 15% was of Cement

grade, 12% was of 45-50% Al2O3 grade, 7% was of below 40% Al2O3 grade,

2% was of Refractory grade and one percent of production was reported

together in 50-55% Al2O3, 55-60% Al2O3, Abrasive and Chemical grades during

the year under review.

Odisha continued to be the leading producing state and accounted for about

36% of the total production. Next in the order of production were Gujarat (20%)

Jharkhand & Maharashtra (13% each), Chhattisgarh (12%), Madhya Pradesh

(5%) and the remaining one percent was produced by Goa, Karnataka and Tamil

Nadu.

Mine-head stocks at the end of 2012-13 was 6,902 thousand tonnes as

compared to 7,988 thousand tonnes at the beginning of the year. About 90% of

the total stock was held in Gujarat at the end of the year. The average daily

employment of labour in bauxite mines was 6,905 in 2012-13 as against 7,684

in the previous year.

It has always been seen that in the cases i.e. for Bauxite there remains a

demand and supply gap as demand is always high in respect of supply.

2.5 Imports V/s indigenous production

The country has large resources of Bauxite, occupying the sixth place in the

world’s total resources. The resources of metallurgical grade Bauxite are quite

adequate while those of the chemical and refractory grade Bauxite are relatively

limited considering the future requirements. That’s why it is necessary to import

Bauxite of this grade. The quantity and value of import of Bauxite is given in the

following Table-3:

(Source: Ministry of Commerce and Industry)

2.7 Domestic Markets

The bauxite of the lease area is of metal grade (+40% Al2O3 on an average),

therefore is suitable for Aluminium plants, like NALCO, Hindalco and BALCO.

2.8 Employment Generation (Direct & Indirect) due to the project

Actual requirement of manpower is generally worked out after industrial

Engineering study during project implementation stage. However, a preliminary

estimate has been made to indicate the order of manpower requirement. The

detail of manpower requirement is given in Table-5.

3.0 Project Description

3.1 Type of Project

As per Gazette notification of Ministry of Environment Forests and Climate Change

(MoEF&CC), New Delhi all projects greater than 50 hectare falls in category “A”.

As in this case, the lease area is 696.734 hectare, so this project falls in “A”

category. The extracted bauxite will be used in proposed aluminium refinery (3.0

MTPA) in Rayagada district, Odisha.

Bauxite is a naturally occurring rock which is site specific due to its geological

origin. No alternative sites are proposed.

3.2 Location (map showing general location, specific location, and project boundary &

3.3 Details of alternate sites considered and the basis of selecting the proposed site,

particularly the environmental considerations gone into should be highlighted

Bauxite is a naturally occurring rock which is site specific due to its geological

origin. No alternative sites are proposed.

3.4 Size and Magnitude of Operation

The total geological reserve is 70 million tonnes, out of which 47 million tonnes

have been considered as mineable reserves.

Of the total mineable reserves, about 34 million tonnes occur in the western block

and the balance 13 million tonnes in the eastern block. It is proposed to

undertake mining operation initially in the western block having reserves of 34

million tonnes with an average alumina 43.5 % and silica 1.42 % which would last

for about 10/12 years at the end of which the eastern block will be taken up.



Mine general layout

General layout of the mine showing the proposed mining areas.

Overburden/waste and topsoil dumps, crushing plant, service centre, electric sub-

station, on-ground water reservoir, explosive magazine, haul roads, roads to

crusher house and waste disposal area etc. Mine general layout is enclosed as

Annexure-IV.

3.5 Project Description with Process Details

It is proposed to carryout mining activities at two locations in the western block,

namely Area-1 and Area-2. Two to three bauxite benches will be developed in

each of these areas. However, the two areas will merge in due course. Process

flow sheet is shown in Figure-1.

Based on the respective reserve base and average grade, it is planned to

excavate about 70 % of the annual requirement of bauxite from Area-2 and about

30% from Area-1. The suggested quantum of excavation from two areas is,

however, provisional only, and maybe adjusted suitably depending upon the

quality requirements and day to day situation in the field.

In order to ensure sustained availability of bauxite, the development work of

overburden removal will continue during production stage. The overburden raised

will be disposed-off to the waste stockpile and the r.o.m bauxite will be delivered

either to crusher house directly or to r.o.m Ore stockpile, the space for which has

been provided near crusher house.

Layout of Mining Benches

The layout/orientation of the mining benches depends mainly on:

i. Method of working;

ii. Topography of the area;

iii. Degree of variations in grade within the deposit;

iv. Degree of intercalations in the deposit;

v. Required output of r.o.m material per day; and

vi. Degree of pit blending required for quality control.

Taking the above factors into considerations, it is proposed to advance the mining

faces generally from east to west. The benches are planned to be laid accordingly.

Further it has been planned to leave a barrier all around the periphery of

adequate width as required under relevant mining laws and other statutory

provisions to prevent boulders rolling down or Surface runoff spilling into the hill

slope. A green belt is to be created on the barrier.

Bench Height

At kutrumali, the bench height in a 10 m slice may vary from place to place

depending upon topography, as well as varying thickness of overburden and ore.

The benches are proposed to be planned generally to follow the contour and

topography without much loss on dilution.

Accordingly, the overburden having varying thickness, maximum being about 9 m

in Area-1, will be removed ahead of bauxite excavation. The bulk of the bauxite

will be mined at 10 m bench height while benches of 5m height will be developed

in places. However, some of the benches, for both bauxite and overburden, will be

less than 5m height and will be exploited by ripping. Bauxite of 2m to 4m

thickness occurring immediately.

Overall Pit Slope

A steep overall pit slope is expected to be stable with 10 m bench height.

However, to assess this aspect more precisely, certain additional information such

as angle of friction and coefficient of cohesiveness of the rock are required which

are not presently available. It is, therefore planned to maintain the overall pit

slope at 45 degree.

Mine Drainage

The kutrumali plateau has almost a flat topography except at the western part

where the khondalite is exposed. The natural drainage, generally in the southeast

direction, drains the surface run-off into valleys which ultimately converges with

the main water courses.

During the initial years of mine operation, top soil and overburden excavated shall

be dumped at the selected sites. Peripheral drains all around the dumps shall be

made to trap rain water washing out of the dumps, which in turn will reduce the

load of suspended solids in the discharged waster. Sump pits will be provided

along the length of the drains for effective trapping of rain water washings and

discharging the clear overflow water to the nearby streams.



It is observed that ground water level at kutrumali region generally lies between

800 to 900 m above MSL which in words about 300 m below the plateau top.

Further, during drilling operation in kutrumali plateau, no sub-surface water to be

encountered to a level up to 1000 m above MSL. Hence, the effect of mining on

ground water is extremely remote.

Crushing Plant

The ore being of high grade, any preliminary treatment/beneficiation is not

envisaged at the mine head. However, to enable smooth and easy transportation,

the minus 800 mm r.o.m. bauxite will be required to be reduced to a suitable size

prior to delivering the same to the long distance transportation system. Crushing

plant and conveyor system to process and transfer 3 million tonnes of bauxite per

year as required by the alumina plant.

The crushing plant will consist of four sections namely:

i) R.O.M ore stockyard;

ii) Crushing section;

iii) Belt conveyor system; and

iv) Surge bin.

R.O.M Ore Stockyard

The ore transported from the mine may be dumped directly into the crusher or to

the stockpile depending upon the grade of bauxite and the requirement of the

crushing plant. Subsequently bauxite from the stockpile may be reclaimed in

appropriate proportions conforming to the stipulated blending requirement and

dumped into the crusher hopper.

Crushing Section

Receiving Hopper

One r.c.c. hopper will be provided at the crusher house to receive the ore directly

transported from the mine and dumped by 35 ton rear dump trucks. Ore

reclaimed from the r.o.m stockpile by front end loader and hauled by 35 ton rear

dump trucks will also be received in this hopper. The rear dump trucks will

approach the hopper though a ramp. The hopper will be of about 100 tons

capacity and fitted with MS grid on top to arrest stray plus 800 mm boulders. The

oversize boulders will be removed from the top of the hopper, fragmented with

the help of a hydraulic rock breaker provided for the purpose, and recharged into

the hopper from time to time.

Apron Feeder

The hopper will be equipped with a heavy duty apron feeder of 2000 mm x 7500

mm size suitable to withstand the load of big boulders dumped by 35 ton rear

dump trucks from large tipping height. The apron feeder will be driven by

thyristor controlled variable speed D.C. motor, and draw out and deliver the

material at a regulated rate to a set of stationary drizzly.



Stationary Grizzly

A set of stationary grizzly of robust construction and 2000 mm x 4000 mm size,

having wedge shaped opening tapering out towards the discharge end, will be

installed ahead of the crusher for scalping out as much minus 150 mm fraction as

possible from the r.o.m material to avoid unnecessary volumetric loading of the

crusher.

Crusher

Oversize of the grizzly will be fed directly to a crusher to reduce the same to

minus 150 mm. considering the size and other, physical characteristics of the feed

ore, throughput rate and the stipulated product size, it is proposed to provide a

toothed double roll crusher of 1700 mm dia x 2000 mm width. Each of the rolls

will have separate squirrel cage induction motor drive, and will run at different

speeds to ensure efficient crushing by the process of compaction and shearing.

Belt Conveyor System

A belt conveyor system will be provided to collect the minus 150 mm crushed

material and the scalped product, and transfer the same to the surge bin, located

near the long distance bauxite transport conveyor system. Each of these

conveyors will be 1000 mm wide operating at a speed of about 2 m per second,

and will be laid over a fairly level land avoiding the promising mining areas to the

extent possible.

Surge Bin

A surge bin complex will be provided to collect the minus 150 mm material and

feed the same at an uniform rate to the long distance transport system.

Bin Compartment

The surge bin will be of r.c.c. construction and have 2 compartments, each of 500

ton capacity. The crushed material of kutrumali mine will be delivered in one

compartment. The other compartment will be used for crushed material conveyed

from Sijimali at a later date. The bin will be enable to even out any fluctuation in

the feed rate of the incoming material and maintain a uniform rate of loading of

the long distance transport system throughout the period of its operation.

Apron Feeder

An apron feeder, 1500 mm x 6000 mm will be provided below each of the

compartments of the bin for drawing out and delivery of the material.

Belt Conveyor

A belt conveyor, 1000 mm wide and operating at about 2 m per sec, will collect

the material discharged by the apron feeder and transfer the same to the long

distance bauxite transport system. The capacity of this conveyor will be

augmented by suitably speeding it up, to match the envisaged transfer rate of

2000 tons per hour after commissioning of Sijimali mine.



Other Facilities

Other facilities envisaged to be provided for smooth functioning of the sizing plant

are briefly described below:

Crane and Hoist

The crusher house will be equipped with a 20/5 ton capacity E.O.T crane for

maintenance and upkeep of equipment there. The crane will also be used to

handle and remove the oversize boulders arrested by the MS grid fitted on top of

the receiving hopper. Besides the crane, mechanical traveling hoists of

appropriate capacity will be provided in the conveyor junction houses and the

surge bin.

Belt Scale

An electronic belt weight will be provided on belt conveyor to record and indicate

the rate of transfer of material.

Metal Detector and Magnetic Separator

A metal detector consisting of a search coil and a solid state control unit will be

provided on belt conveyor to facilitate detection and removal of tramp metal

pieces from bauxite being despatched to the alumina plant. The search coil

mounted on the conveyor senses the presence of any unwarranted metal piece in

bauxite, and through the control unit, activities an overband magnetic separator

which in turn ejects the piece from the system. In the event of failure of the

ejection device, a second metal detector installed further downstream will actuate

the trip circuit of the conveyor drive to facilitate manual removal of the metal

piece.

Automatic Sampler

A cutter type automatic primary sampler will be mounted at the discharge end of

belt conveyor for collection of representative samples at predetermined intervals

as required for monitoring of quality of despatchable bauxite. Along with sample

collector, facilities for preparation of samples consisting of two stage crushing,

handling and secondary sampling will be provided.

Dust Abatement Facilities

To combat dust nuisance caused by crushing, screening, transfer through chutes

etc, it is proposed to provide appropriate dust extraction facilities comprising

multiple collection hoods and ducting, bag filter, stack/exhaust duct in crusher

hoods and ducting, bag filter, stack/exhaust duct in crusher house, surge bin and

junction houses. The dust extraction system will be designed to limit the dust

content in the buildings to 5 mg per Nm3 for breathable fraction and that in the

stack discharge to 50 mg per Nm3. The dust arrested in the bag filters will be

recharged to the belt conveyors.

Besides the dust extraction system, water will be sprinkled at the receiving

hopper through appropriate header, pipeline and sprinklers to control generation

of dust.



3.6 Raw materials required along with estimated quantity, likely source,

marketing area of final products/s, Mode of transport of raw Material and

Finished Product.

No raw material will be required for production of Bauxite.

Use of Mineral

The bauxite from Kutrumali deposit will be used for production of metallurgical

grade alumina. The proposed alumina plant will be located at a distance of around

9 km in East direction from this bauxite deposit.

Bauxite Transportation

The bauxite raised from Kutrumali mine will be used for production of

metallurgical grade alumina at the plant proposed to be installed by L&T located

at about 9 km away from this deposit. The bauxite will, therefore, have to be

transported to the proposed alumina plant. After considering various options, it

has been decided to provide a belt conveyor system for the purpose. The belt

conveyor will be of either steel chord supported or conventional idler supported

type, or any other state of the art type, laid on generally on a declining ground

slope.

The drive house for the conveyor system will be located on the feed end at

Kutrumali plateau top and conveyor will receive bauxite feed from the surge bin

via apron feeder. However, most of the conveyor system will be installed outside

the Kutrumali ML area and its alignment will be generally follow the gorge of a

stream to terminate at the proposed plant site. The access road between

Kutrumali the alumina plant site is planned to be laid as close to the conveyor

installation as possible to facilitate its regular inspection, upkeep and

maintenance.

3.7 Resource optimization/recycling and reuse envisaged in the project, if

any, should be briefly outlined.

Water will be accumulated in the excavated mined out pit area during rains and

the pits shall serve as natural ground water recharging structure. As a result of

extraction of mineral, the rate of charging of ground water is likely to be

increased considerably.

3.8 Availability of water its source, Energy/power requirement and source

should be given

Water Source and Requirement

It is proposed to tap water from Naragul nala at an approximate distance of 3.5

km from Kutrumali hilltop.

Water will be required in the mining area for sprinkling on the roads to suppress

the dust, watering of green belt/green verge and trees planted to comply with

requisite EMP measures, miscellaneous industrial use, and drinking and sanitation.

The water requirements, source of water and distribution system envisaged for

Kutrumali are briefly discussed below:

For the purpose of design of water system, projected water requirement for

Kutrumali is given below Table-7:



TABLE-7

WATER REQUIREMENT

Consumer Requirement of Water (m3/day)

Mine road sprinkling 250

Provision for vegetation 50

Industrial use 125

Drinking and sanitation 75

Total 500

Power requirement

The requirement of power for crushing plant, bauxite transport conveyor, service

centre, water supply units, mine and plant lighting and other miscellaneous

consumers has been estimated as follows:

Annual energy consumption, 16.5 x 106 kwh

15 min maximum demand, 4.0 MVA

Source of Power

It has been envisaged that power will be made available at the main receiving and

step-down substation (MRSS) of the proposed alumina plant by Odisha State

Electricity Board (OSEB) over 132 KV double circuit overhead line from Theruvali

substation. Power will be stepped down to 33 KV at the MRSS. It is also planned

to establish one in-house captive power at Alumina Refinery plant based on co-

generation system to meet the power demand. The in-plant power generation will

be connected to the 33 KV system.

33 KV power will be taken to Kutrumali mine over double circuit overhead line

from the 33 KV substation of the alumina plant. Further 33 KV power to Sijimali

mine will be taken over double circuit overhead line from the 33 KV substation at

Kutrumali. The 33 KV overhead line will generally follow the bauxite transport

conveyor alley.

Requirement of the construction power will be met from the DG sets.

It is also envisaged to install solar panels to produce green energy and fulfil part

of the requirement.

3.9 Stacking of Mineral and Disposal of Waste

Opencast working: taking into consideration factors, such as nature of occurrence,

geological setting of the deposit, topography, scale of operation, ore to waste

ratio etc., it is proposed to adopt opencast mechanised mining by top slicing

method in multiple benches. Proposed five year production details are shown in

the Table-8.

4.0 SITE ANALYSIS

4.1 Connectivity

Kutrumali Bauxite deposit is located in Thuamul-Rampur, Kashipur and Rayagada

sub-divisions in Kalahandi-Rayagada district. The bauxite deposit is located at a

distance of about 34 km from Rayagada town. Rayagada is the district

headquarter and is connected by SE railway.

The state highway connects Sunger with Rayagada via Kashipur, the sub-

divisional head quarter. From Sunger, the deposit is approachable by 11 km long

fair weather village road, followed by a 4 km kutcha road from the foothill to the

plateau top. The total road distance from Kutrumali hilltop to Rayagada is

approximately 97 km.

4.2 Land Form, Land Use and Land Ownership

The abstract of the details of land schedule and landuse is given in Table-9.

Total 12.61 1.62 43.09 617.45 21.93 696.73

It may be seen from the above table that the bulk of area is non-forest

government land. The total forest land covers about 8.22% of the ML area is

forest land (forest land- 14.23 ha [village forest – 12.61 ha & DLC forest – 1.62

ha], proposed reserved forest- 43.09 ha).

4.3 Topography

The area forms a part of the Eastern Ghat hill ranges which have a general NE-SW

trend. Series of hills ranging in an elevation between 1000 m and 1400 m have

been interspersed with valleys having an average elevation of 850 m and are

dotted with several isolated hillocks.



The main drainage pattern in this area is controlled by a number of streams,

which drains their water into Nagavalli River that flows from north to south. The

Barha Nadi, a tributary of Nagavalli River, flow along northeast direction on the

northern side of the Kutrumali plateau. The streams originating from the northern

part of the plateau drains the water into Barha Nadi. No streams are passing

through proposed ML area.

4.4 Existing Land use Pattern

The prevailing land use pattern in the study area has been divided into two

distinct zones, namely (i) the core zone covering an area about 7.0 sq.km over

the Kutrumali plateau top where the mining activities will be confined and (ii) the

buffer zone covering a total land area of 720 sq.km (exceeding 10 km radial

coverage).

Core Zone Land Use /Land Cover

The proposed mining site at Kutrumali plateau is principally a stony waste land.

However, there are patches of tree cover at the edge of plateau. The broad

distribution of the prevailing landuse/landcover in the core zone of the study area

as observed is presented in below Table-10.

Total 696.73

Note: However, as per legal status, 43.09 ha of land area in northern sector of

plateau falls under Mohangiri proposed reserve forest. This area accounts for

total plateau land surface.

Buffer Zone Land Use/Land Cover

The buffer zone area has got substantial forest coverage of varying canopy

density. This is one way beneficial to the proposed project. The vast forest

coverage provides substantial ecological resources which are not being affected by

the present project activities. In the buffer zone, five major forest types are

recognised in Rayagada and Kalahandi forest divisions. The details of forests are

given in Table-11.

5.0 PLANNING BRIEF

5.1 Planning concept (type of industries, facilities, transportation etc.) Town

and country Planning/Development authority Classification

The bauxite mining project of M/s Larsen & Toubro Limited, Mumbai is located at

Villages- Kutrumali, Podapai, Majhigaon, Murlimuhin, Melrapa, Salabali villages

and Mohangiri Reserve Forest (Proposed) under Thuamal Rampur Tehsil of

Kalahandi District; Padelgura, Alutunga under Kashipur Tehsil and Sadalasa under

Rayagada Tehsil of Rayagada District , District- Kalahandi & Rayagada, State-

Odisha over an area of 696.734 ha (1721.680 acre). The proposed capacity of

the project is 3.0 MTPA. The bulk of Mine Lease area is non-forest government

land. Open-cast mechanized mining method without blasting is proposed for this

project

5.2 Population Projections

The project will employ most of the workers from nearby villages. Only

supervisory staff will be hired from outside. There will not be any increase in

population due to the project. However, few people from other areas may migrate

in this area for business opportunities. Village wise population of the core zone is

given in Table-12.

The above villages partly/fully fall within the proposed ML area. The actual

project affected people are 377 from 105 families out of the above.

5.3 Land Use planning (breakup along with green belt etc.)

Land Reclamation - Concomitant to Mining

During the course of mining, the original topography will be disturbed. It becomes

necessary to reclaim the degraded land so as to bring back to its approximate

original topography. It is planned to remove the top soil first and to dump at the

selected sites. Removal of the overburden and waste material would follow

thereafter and suitably dumped at the selected sites. During the operation of the

mining, concomitant reclamation of the land during the first five years may not be

possible because:

i) Opening of the different benches at different levels simultaneously for

achieving the desired tonnage and grade;

ii) Irregular and heterogeneous nature of the bauxite and non-exposure of

bottom profile of mineralization; and

iii) Unfavourable topography limiting the total backfilling of the mined out

areas.

Hence, it has been decided to take up the restoration of the degraded land in the

western block after exploitation of the bauxite. The restoration will cover

backfilling and terracing of the mined out area with overburden /waste and

surfacing the same with topsoil. The fast growing trees like Auriculiformis (Sona

Jhuri), Cassia Siamea (Chakunda), Albizzia Lebbek (Siris), Leucaena Leucocephala

(Suo Babul), Bombax Malabaricum (Simul), Butea Frondosa (Palas) and shrubs

will be planted to stabilise the reclaimed land. Landuse pattern of project area is

given in Table-13. The year wise plantation programme as proposed, is

presented in Table-14.

Land Restoration – Post –Mining

Biological Stabilisation

Since the mining operation will degrade the landscape, it will be prudent to plan

and execute the post-mining restoration with an objective to recoup the lost

vegetation, restore the degraded land and impart advantages and benefits which

would not have otherwise been conceived. In European and other countries,

there are numerous examples where the reconstituted landscape has created

benefits with joint efforts of the mining agencies and the Government

authorities.

At the end of the total exploitation of the deposit, about 30 per cent of mine

leasehold land would be degraded due to the mining. It is proposed to reclaim

the degraded land to bring back to it’s approximate original contour by

backfilling and terracing the overburden and waste materials. Most of the land

would be suitable for plantations. It is proposed to plant quick growing trees,

shrubs and creepers taking advantages of the climatic conditions, altitude and

rainfall so that these vegetations cover up the dump quickly and stabilize the

same to prevent soil erosion.



Peripheral drains are to be provided around the dump sites and trees are to be

planted along both the sides of the drains. Local species of the vegetation’s

which attract the fauna like birds, will also be planted. Suitable trees capable of

arresting surface run-off will be planted.

5.4 Assessment of Infrastructure Demand (Physical & Social)

The access roads to the nearby villages and to Kutrumali plateau from Sunger

are not metalled roads but jeepable throughout the year except during the

period from June to October covering monsoon and part of post-monsoon

period. Preference will be given to local labour from nearby villages. Other

requisite infrastructures as transport of mine labours will be made available by

way of jeep and two-wheeler. Medical facility will be available for First Aid and

providing ambulance service at the project site.

5.5 Amenities/Facilities

The service centre will be provided with auxiliary facilities, namely quality

control centre, repair and maintenance shop, stores, training centre, canteen,

ambulance room, transport, communication facilities, the utility supplies, namely

power and water supply systems, and the auxiliary facilities.

6.0 PROPOSED INFRASTRUCTURE

6.1 Industrial Area (Processing Area)

The lease area shall be the processing area for the mining works. No other

industrial area has been proposed in the applied area.

6.2 Residential Area (Non Processing Area)

A separate campus has been provided on the south side of the crushing plant

where the administrative building and site service facilities will be located.

6.3 Greenbelt Development / Afforestation

Greenbelt development: As a part of the eco-restoration programme, it has been

decided to carry out afforestation in the following mine leasehold land:

i) Creation of greenbelt along the periphery of the mining area to take

effective measures for dust suppression and noise baffling, reducing

unpleasant visual impacts and prevention of soil erosion and landslide.

Further it has been planned to leave a barrier all around the periphery of

adequate width as required under relevant mining laws and other statutory

provisions. The vegetation of cover is planned to be created with a mixed

vegetation of quick growing trees and hardy indigenous slow growing trees.

ii) The greenbelt is required to be developed on both sides of the conveyor

gallery, haul roads, junction house, surge bin, r.o.m ore stockyard,

administrative office, service centre, magazine building, etc.

iii) Biological stabilization and protection of old and new waste dumps by

plantations and providing garland drains around these overburden/waste

dump sites. Since the overburden and waste dump would not be utilized

with in the period of five years or so, it is proposed to plant quick growing



trees, shrubs and creepers to cover up the dump and stabilize the same to

prevent erosion. The afforestation programme as envisaged for 2nd, 3rd, 4th

and 5th year is shown in Annexure-V.

Nursery

For taking up afforestation, road side plantation, garden development etc., it is

essential to develop a small nursery which is proposed to be developed near

administrative building.

Landscape Garden

An area near administrative building which commands the beautiful valley site is

proposed to be developed as landscape garden with lawn and flower beds.

Pisciculture

Some of the pits ranging in depth in between 13 m and 15 m will be utilised to

impound rain water to convert into ponds. These ponds will be utilised for

pisciculture growth and greenbelts will be developed around the pond.

6.4 Social Infrastructure and Benefits

The proposed mining project at Kutrumali will improve their present economic

conditions by having direct and indirect employment opportunity as miners,

skilled/semi – skilled workers, contractor’s labours etc. Thus the project will

have ‘significant beneficial impact on the economic condition and life style of the

local people.

Apart from this the following benefits will accrue to the local people:

- Road facility

- Medical camps

- Social awareness camps

- Secondary employment opportunities

6.5 Connectivity

The access road will be laid alongside the belt conveyor connecting Kutrumali

and Alumina plant site. Besides transportation of machineries for development

and construction, the road will also be used for regular transportation of

employees from township to mine, maintenance a regular surface linkage

between mine and plant.

6.6 Drinking Water Management (Source & Supply of Water)

It is proposed to tap this quantity of water from Naragul nala at an approximate

distance of 3.5 km from Kutrumali hill top. Total requirement of water amounts

to about 500 m3 per day. The project has not envisaged using tube well water

for drinking purpose. However, for drinking purpose the water may be

disinfected through chlorination.



Water supply distribution scheme

To enable tapping of water, it is proposed to construct a weir on the nala and an

intake well on the nala bed upstream of the weir. On the basis of 10 to 12 hours

working hours per day, two pumps (one working and one standby), each 50 cu

m per hour capacity at 500 mwc head will be provided to pump water from the

intake well to a ground water reservoir in the mine.

6.7 Sewerage System

A sewerage system of septic tanks followed by soak pits shall be provided for

the project area.

6.8 Power Requirement, Source/Supply of Power

The requirement of power for crushing plant, bauxite transport conveyor, service

centre, water supply units, mine and plant lighting and other miscellaneous

consumers has been estimated as follows:

Annual energy consumption, 16.5 x106 kwh

15 min maximum demand, 4.0 MVA

Source / Supply of Power

It has been envisaged that power will be made available at the main receiving

and step-down substation (MRSS) of the proposed alumina plant by Odisha state

Electricity Board (OSEB) over 132 KV double circuit overhead line from Theruvali

substation. Power will be stepped down to 33 KV at the MRSS. It is also planned

to establish one in-house captive power at Alumina Refinery plant based on co-

generation system to meet the power demand. The in-plant power generation

will be connected to the 33 KV system.

33 KV power will be taken to Kutrumali mine over double circuit overheat line

from the 33 KV substation of the alumina plant. Further 33 KV power to Sijimali

mine will be taken over double circuit overhead line from the 33 KV substation at

Kutrumali. The 33 KV overhead line will generally follow the bauxite transport

conveyor alley.

It is also envisaged to install solar panels to produce green energy and fulfil part

of the requirement.

6.9 Solid Waste Management

Disposal of Waste/ Overburden

The waste generated in course of pre-mining development and subsequent

mining operation will consist of topsoil and overburden comprising mainly

laterite and low grade unusable bauxite. The rate of generation of

overburden/waste is expected to be of the order of 1.2 million tonnes per year

considering an average ore to waste ratio of about 1:0.4 in the initial years of

operation. However, during first five years of operation including two years of

pre-mining development, the total generation of overburden/waste has been

estimated at about 5 million tonnes, of which top soil is around 1,91,000 tonnes.



It is planned to stack topsoil and overburden separately on ground till some of

the bauxite benches have been worked out and the bottom of bauxite

mineralisation exposed in some of the benches. Two separate locations have

been selected on almost barren and non-promising zones for dumping of top soil

and overburden/waste. One on the lower eastern part marked OB-1 and TS-1

and the other on the lower western part marked OB-2 and TS-2. About 15 ha

and 7.5 ha of land have been provided for OB-1 and OB-2 respectively.

The waste/overburden loosened mostly by ripping would be loaded on rear-

dump truck by front-end loaders for transportation to waste disposal areas.

Overall height of the stacks would be 20 m, each step being 5 m high. The slope

of the individual terraces will be dictated by the angle repose of laterite which,

considering the size of the material, is about 30 degrees. The overall slope will

be maintained at about 15 to 20 degrees, well inside the stipulated limit. The

garland drain around the dumps are proposed to be provided to arrest the finer

particles of the overburden/waste dump as well as the top soil which are

susceptible to rain water washings.

During the commercial production stage, the loosened overburden benches will

be used for back filling of some of the worked out pits, as and when the same

will be available.
