INTRODUCTION



II-2 M/s Crystal Consultants, Ranchi


2.1 Identification of Project

The mine was opened by Farraka Barrage Project. On Completion of Farraka Barrage Project, the mine was transferred to M/s Bihar State Mineral Development Corporation Limited. a State Govt. undertaking in 1976. On formation of Jharkhand State, the lease was transferred to M/s Jharkhand State Mineral Development Corporation Limited. a Stage Govt. Enterprises. M/s JSMDC Ltd. worked in Forest Land. In absence of regularization of degraded forest, the mine was closed in 2001. The project relates to mining of stone including boulders, (+ 8”), Lump Spawls (4” – 8”) Metals (1” – 2”) & chips (1” –5/8”) (5/8” –1/2”) (1/2” –1/4”) & dust <1/4”, by open cast method of mining. This is an old mine which has been worked in past by the proponent. The mine was closed in 2001.

2.2 Project Proponent M/s Jharkhand State Mineral Development Corporation Ltd, a Govt. of Jharkhand undertaking is the project proponent. It is a company registered under company’s Act. Its Regd. office is located at Khanij Nigam Bhavan, Doranda, Ranchi - 834002. The corporation is run by Board of Directors which is headed by Chairman. Managing Director is the CEO of the company. It is responsible for mining of minerals and their marketing in the state of Jharkhand.

2.3 Nature of Project The project worked till 2001. In 2001 project activities were stopped on account of

expiry of Lease. The project is essentially an opencast mining project. Stone was mined by opencast method of mining. Overburden was removed. Prior to mining of stone. After removal of overburden, stone was mined. For mining of stone, blasting is done. For this purpose, Blast holes ate drilled using Jack hammer Drills. Blasted mass is crushed to required size in jaw Crusher. Products are classified into following sizes.

Boulders - + 8” Lumps (Spawls) - +4” - (-) 8” Metals - (-)2” – (+)1”

- +1” – (-)3/4” - (-)3/4” - +1/2”

- - ½ - +1/4” Dust - <1/4”

Products are dispatched by road/rail. In the new Mining Plan, mining method which was practiced in past will be continued.

Presently there is no crushing & sizing Plant of its own. Materials are handled manually. There is proposal to construct a Material Handling Plant for the mine. Including crushing & sizing of materials after mine is restarted.

2.4 Need & Importance of Project The mine is located in an economically under developed area of the state. Presently only source of employment in the area is agriculture. Due to poor quality of Soil and lack of irrigation facilities, there is mono-cropping in the area which is limited to

Chips



II-3



monsoon season only. Moreover, agriculture yield is low. In this situation there is urgent need for setting up industry that will create additional source for employment and income generation in the area. The area has large resource of good quality of construction stone. The mine under consideration is one of those locations where stone reserve is available. This mine was established to mine the stone. This created source for employment in Primary, Secondary & Tertiary Sectors. Employees in the project are mostly local.

Importance to Region The mine exploits the locally available natural resource. The mine has created source for livelihood for local people by creating employment opportunities in primary, secondary & tertiary sector. Due to this mine, physical infrastructure in terms of roads, power network in the area will also improved. The increase in earning capacity of the local population will brought economic prosperity in the area. The project contributes to State revenue in terms of Cess, Royalty & Sales Tax. Importance to Country The country is on a path to industrial & economic development. Infrastructure development in term of construction of roads, bridges, power projects, industrial structures ate key to accelerated growth. And construction of these infrastructure needs construction materials including stone boulder metals, chips etc. This mine produces very good quality of stone products required by construction industry in the area.

2.5 Demand & Supply

There is wide gap between demand and supply of boulders, ballast and building aggregates in Pakur area where Chandula- Simalgoda Project is situated. The major consumers of boulders are Railway, Irrigation Depts. of the Govt. of Bihar and West Bengal and Road Construction Deptt. Govt. of Jharkhand & road and building construction sector operating in this region. The requirements of stone chips of various Govt. agencies and private construction companies are to be met from quarries operating in this area. Against the above back ground of demand the supply position from various

consumer in the area is not satisfactory because of actual production being much

less compared to the demand resulting in to delay of most of the construction

projects.

Also, the small owners lack financial capacity and technical expertise and are unable to expand their activities to augment production to meet such huge demands. Moreover, supplies are, occasionally found to be erratic and necessitate requisite provision for stacking and reclaiming to be a deterrent to private owners in making investment for production.



II-4



Under the above circumstances it is considered worthwhile opening the existing Chandula- Simalgoda project to produce at least 9.20,000 M3 per annum of various products i.e. boulders, lumps, metals and chips etc.

2.6 Imports vs. indigenous Production

Demand for stone products required for construction industry in the region can be met by locally available resources. There is no need for importing the stone product from outside. Indigenous production can meet the demand. The need is to exploit locally available resources in a scientific manner to protect environment.

2.7 Export possibility

The demand for stone products in the region is such that the mine can meet the demand. Export of this material may not prove to be a viable proposition However there is demand for this quality of construction material in neighboring country Bangladesh.

2.8 Employment Generation The mine will create employment opportunity in Primary, secondary & Tertiary sector. The project employs about 200 persons.

The Secondary Sector i.e. Service Sector also offers employment to local people. Besides above in the tertiary Sector including Construction Sector which uses the products of this Project also offer employment to local population.

PROJECT DESCRIPTION



III-2



3.1 Type of project The Project under consideration is a mining Project that will produces stone products for use construction industry for roads, building, Bridges etc. and railways.

This is an independent project. 3.2 Location

Now realizing that there is huge demand for stone products for construction & railway, the proponent has decided to start the project again. Chandula-Simalgoda project is situated at a distance of about 6 Kms. to the North West of Barharwa Jn. Railway station on Patna-Howrah route via Bhagalpur and Sahibganj Loop line of Eastern Railway. Barharwa Jn. is situated at a distance of about 351 Kms. from Patna on the above route. The H.Q of the project is at Sahibganj which is situated at a distance of about 55 Kms. the project is approachable by Barharwa – Sahibganj Road via village Dighi. The project is also approachable by road from Ranchi at a distance of about 539 Kms via Giridih , Dumka & Littipara. A metalled road connects the mine with Barharwa Town. The project is provided with P&T facility Telephone connected to Barharwa Exchange. The Post Office at Barharwa is about 6Kms, form the mine. The project site is located in tribal area and sparsely populated. The general living condition of the people is poor. The area around the project is partly agriculture, partly barren and remaining are covered with thin forest. The annual rainfall varies between 40˚(100 c.m) to 60” (150 c.m)

The general location of the project is shown in Plate - I index Map. The specific location of the project is shown in Plate – II study area & location Map

3.3 Reserve

So far the mining operation has been carried out on the southern slopes of Chandula – Simalgoda hills. In Chandula zone mining activity is limited within the contour 765’ to 865’ whereas in Simalgoda zone Quarrying till date is confined between 840’ and 900’ contours.

However, based on the geological reasoning like mode of origin, behavior of rocks and existing quarries etc. an average thickness of 30m 40m in Chandula and Simalgoda respectively can safely be considered for consideration that no undesired rocks occur in these hills. Following reserve of basalt would be available from the area under lease of Jharkhand State Mineral Development Corporation Ltd.

After giving 50% allowance for voids, O.B. mining leases etc. the recoverable reserve

could be of the order of 476.63 million Cft. About or 13.0 million cubic meters.

3.3.1 Proposed Method for OB Removal & Mining of Minerals

Overburden Removal in project was being done manually as its quantum is not much and the material being soft, no blasting operations was needed. The thickness of overburden varies from 2 to 4 meters to occasionally none. The present system of removal of OBR by manual means would continue.

3.3.2 Past System of Mining

This project produced boulders for supplying to Farakka Barrage Project and stone chips of sizes for supplying to various consumers. The system of mining followed was open cast method of mining. Boulders were produced from selected patches. The production was mostly manual

except for stray drilling and blasting when big pieces of boulders are to be broken to

a size of 40 of 50kgs. i.e. (+9”) acceptable to Farakka while producing boulders some

spawls were also produced which vary in size from 4.5 to 27.5 kg.i.e. from (+)5” to (-

) 9”. The boulders produced were stacked near face for transportation by truck to

Farakka Project.

For production of stone chips there is separate quarry face where OB was removed

manually to expose stone face which was drilled by jack hammer drills and blasted

by using high explosives or ANFO (Ammonium Nitrate with fuel oil). After blasting

3” to 5” size pieces were loaded manually into trucks for transportation to crusher

site. Oversizes were broken manually to 4” sizes which were called chellies for

feeding into Jaw Crushers. The crushed material is screened into three sizes viz. (-)

¾’ (+) 5/8,(-) 5/8”+1/2” to 1/4”. About 10% of the total feed to the crusher comes

out as dust which got little commercial market.

Machinery used was diesel compressor, compressed air, jack hammer drills,

electrical and diesel crusher etc.

3.3.3 Pumping As stated earlier, the workings will be above ground water level and drainage problems would not arise. However, during rainy season, working quarries will collect rainwater, which has to be pumped out. For this purpose a provision has been made for a HP motor.

3.3.4 Crushing & Material Handing

It is proposed to install a Material Handing Plant for production of all the products mechanically. The various products planned to be produced are as follows:

Boulders - + 8” Lumps (Spawls) - +4” - (-) 8” Metals - (-)2” – (+)1” - +1” – (-)3/4” - (-)3/4” - +1/2” - - ½ - +1/4” Dust - <1/4”

ROM from the pits will be transported by dumpers and dumped into receiving bunker over a grizzly. Any oversize will be broken manually to pass through the apertures. The capacity from the receiving hopper to a fixed grizzly screen with 8” apertures to remove -8” size. The +8” to -24” size material will be fed to the primary crusher direct from grizzly screen for crushing to – 8” size. The capacity of the primary crusher will be 200 TPH. The under flow of grizzly screen and crusher product of primary crusher will be fed together a vibratory screen of 4” apertures product + 4” to -8” size lamps for supply to IRCON. The underflow -4” material will be fed into two numbers of secondary crusher of 100 TPH capacity each for crushing to -2” size. The underflow from 2” vibratory screen and crushed product from secondary crusher will be passed through 4 deck vibratory screen to separate.

Boulders - + 8”

Lumps (Spawls) - +4” - (-) 8” Metals - (-)2” – (+)1” - +1” – (-)3/4” - (-)3/4” - +1/2” - - ½ - +1/4” Dust - <1/4”

There will be two such systems for two secondary crushers. These products will be carried by belt conveyors to 50 tones over head hoppers for direct loading into tipping trucks through chutes and transport to Rly. Siding or to the stack yards as and when required. The wagons will be loaded by pay loader. Although provision has been made in the Material Handling Plant for production and separation of lumps and metals to meet the demands of IRCON, this plant will have flexibility and capacity to convert the lumps and metal into chips. In case there is no future sustained demand from the railway or other party for lumps and metals. Provision of Rs. Two hundred lakh has been made.

3.4 Raw Material The mining & allied activities requires only explosive as raw material. Other inputs

required for mining and allied activities include mining equipments, Transport vehicles, Land, diesel and Power.

3.5 Resource Optimization Resources required for the operation of the project include

Land Mining equipments Explosives. Power Diesel Manpower

At the planning stage of the project all efforts have been made to optimize use of resources & as far as possible to recycle it.

(1) Land – Project has been planned to minimize use of land & particularly agriculture

land and forest land Mining scheme has a life of only 5 yrs. During this period mine void will not be available for backfilling. Those pits where mining is proposed all have sufficient reserve. Back filling will sterilize the reserve as such no backfilling of pit is envisaged during the currency of this mining scheme. At the end of plan period, there is no area that is available for reclamation. (a) Explosives

In order to minimize quantity of explosives used for blasting, trial Blasting has been conducted in the field to determine optimal powder factor. Use of explosive taking into account the powder factor determined will minimize quantity of explosives for blasting.

(b) Power All the electrical equipments have been planned & selected with maximum efficiency.

(c) Diesel In order to minimize the consumption of diesel, it is proposed to provide a field work shop to facilitate regular maintenance and repair of diesel, based mining equipments. Properly maintained equipments consume optimal quantity of fuel.

3.6 Water Requirement & Source. Water requirement for the project has been assessed as 45 KLD. The break-up of this estimated quantity is given below. (A) Mine Site

A.1 Potable Demand – 5 KLD A.2 Industrial Demand Dust Suppression - 25 KLD Green Belt - 5 KLD Total - 35 KLD Source – Potable - Open dug well within leasehold area

Industrial Site - 30 KLD from quarry water/sedimentation pond 15 KLD - From Tube Well

3.7 Power The mine is connected to JSEB. However (2 x 500 KVA) D.G sets have been provided as standby Power source.

3.8 Liquid Waste Management

Sources for generation of liquid waste in the mining Project & their estimated quantity are described below. (a) Mine Water

Waste water in mine water will be generated on account of following - Rainwater

In the monsoon, mine pit will collect water due to rainfall over pit area. The rainfall in lease area will generate surface run-off. This surface run-off will drain into mine pit. Since the mine pit is not likely to intersect ground water level, there is no likelihood of seepage of ground water into pit. The quantity of mine water due to rain will be determined by following factors.

Amount of rainfall Area of mine pit Topography of the leasehold Mine water will be collected in Mine Dump provided at

quarry floor mine water will be pumped out in rainy season, if required.

ANALYSIS OF ALTERNATIVES



IX-2



9.1 Proposal under consideration relates to an existing opencast mine which

produces stone. The mine has already been developed most of the

infrastructure required for the operation of mine. Manpower for the mine is

available. Once E.C is obtained, lease will be renewed & mine can be stared. It

is advisable to restart the mine for following reasons.

- Land, infrastructure, equipments & manpower for the project

is available. Very little has to be done to restart the project. All

the equipments, manpower can be used.

- There is sufficient reserve of stone available within the lease

area

- There is demand for the products being produced by the mine.

- The mine provides source for employment & income

generation for local people. Closure of mine will have an

adverse social and economic impact.

- This is a profitable Venture. It is source for income to the state

exchequer.

In view the fact stated above, the project needs to be restarted for social &

economic profit to local population & state Govt.
