b. Brief description of nature of the project: This is Building Limestone mining project for mironr mineral. As per EIA Notification

dated 14th Sep, 2006 and as amended till date, the project falls under; Category “B2” by

considering the area of project is 1.05.82 Ha. only. A location map of the project is shown

in the next section. It has been proposed to excavate maximum 30000 TPA of Building

Limestone mineral, from the S. No. 1/14P1 and 1/14P2 by open - cast semi mechanized

mining method. The LOI area is 1.05.82 Ha. Total geological reserves of Building

Limestone are 1,74,750 MT . The expected life of mine will be 20 years. The mineral

Building Limestone will be transported by hired trucks to the consumers.

At the end of lease period, the total excavated area will be 0.884 ha. The entire excavated

area will be used as a water reservoir. Water reservoir so formed, will ultimately help in

recharging ground water and also help in cultivation and irrigation purpose for nearby

area. Water requirement of 6.0 KLD for the proposed project activity will be met by water

tankers supply from nearby village source. The depth of water table is 30 m (Pre-

Monsoon) to 10 m (Post-Monsoon) below the general ground level. Thus, water table will

not encounter during working of the mine.

c. Need of the Project and It’s Importance to the Country/ Region

Building Limestone is basic building material of all civil construction and insfrastructure

development projects. The need of stone is in all types of civil constructions and CC roads.

This mines would be prime source of raw material for the civil and infrastructure

developemtn projects in Saurshatra reginon. There is huge demand fo building stone in

develping state. In case the supply of mineral is not received from this mines production

of constructin job will be seveorly hamppered. Building Limestone Mines are providing

employments to the local Labour in Rural area, as the labour of rural area have no

alternate work for labour, They are Unemployed, Thus this proposed mine will provide

work to many labours and it is a good employment. The Building Limestone is classified

as minor mineral. The operations of the quarries include cutting of stone by cutter

machines.

d. Demand – Supply Gap

Building Limestone is one of the important components in civil construction. It is used

in wall construction and architectural work. It is essential component for infra

structure development. It has high demand in the market due to increased domestic,

industrial and other infrastructural activities. As on date there is a gape of demand and

supply in domestic market and regional market. Quarrying of building stone is running

from decades are facing acute shortage of the minerals from local sources. The

Building Limestone found in the LOI area is low grade for industrial manufacturing.

e. Imports Vs Indigenous Production


5

In the current market scenario, import of Building Limestone is not envisaged. The Building Limestone produced is for indigenous use only.

f. Export Possibility Not applicable as proposed mine is for domestic use.

g. Domestic/ Export Markets Domestic demand is one of the main reason for the rapid growth of Building Limestone business in Saurashtra region. Thus, domestic market for Building Limestone as basic material for civil construction is growing. Building Limestone from the proposed quarry will be used to fulfill the domestic demand. No export is proposed at this stage.

h. Employment Generation (Direct and Indirect) due to the Project

Direct Employment: Highly Skiled (Technically qualitfied) – 2 Skiled - 2 Semi Skiled – 3 Un- skiled - 10 Indirect Employment: Truck driver for transportation, helpers and other ancillary activities of tea stall, workshop to repair trucks for the region which amount to employment of about 40 persons.

No alternative site has been taken into consideration as the mineral (Building Limestone) is available at this site, and held under LOI.

d. Size of magnitude of Operation:

The quarry area of existing Building Limestone mine is 1.05.82 hectare and proposed rate of production of Building Limestone is maximum 30000Tonne/ Year ..

i. Regional Geology: Building Limestone in Porbandar is composed of Sea shells’ mega fossils and known as

Dwarka Bed Building Limestone. The cementing material of the shells is also carbonate


8

mud and concretionary material is underlying it. The rocks of this series are generally

horizontal and occasionally dip 5° to 10° towards south. Strong horizontal laminations due

to current bedding are a common structural feature with presence of minor

faults/fractures. This Building Limestone forms crescent shaped low height mounds.

Outcrop surfaces are quite often pitted due to solution activity. Typically karts topography

is special feature of this area.

The Building Limestone deposit represents crudely defined strike ridge along N-S direction.

The Building Limestone shows a wide variation in thickness. The Dwarka bed Building

Limestone are horizontally bedded shows somewhat lower thickness in topographic

depression and slight bulge in the elevated portion in the region. Building Limestone

outcropping as mounds and ridges exhibit a hard, consolidated, crustified nature compared

to underlying softer horizons.
