favor of Sri. O.Srinivasa Raofor a period of 10 years subject to submission of Approved

Mining Plan within a period of 6 months from the date of issue.

The mine lease area is issued by the Deputy Director of Mines and Geology, Guntur via

Proceedings No.8126/Q/2008, dated: 04-07-2009.

2.2 Brief Information about the Project

The mining lease area of 0.979 hectares/ 2.42 acres opencast semi-mechanized mining is

followed and it has been proposed to produce approximately 3000 tons/ Annum of Napaslabs

Quarry. The nearest habitation, Goli is located at a distance of 0.66 km due SE from lease

area. The mandal head quarters Rentachintala is located at a distance of 4.71 km SE of the

Q.L applied area.

2.3 Need for the Project and Its Importance to the Country or Region

Guntur district produces about 18 to 20% of all the grades of limestone in the state which is

being utilized in cement, sugar, textiles, paper and pharmaceutical industries. A number of

deposits located at Dachepalli (16°35'00" N, 79°44'30" E; 56P/10), Macherla (16°28'30" N,

79°27'00" E; 56P/7), Pillutla (16°32'30" N: 79°54'00" E; 56P/14), Piduguralla (16°28'30" N:

79°52'30" E) and Pondugala (16°41'00" N, 79°40'00" E) are used for cement manufacturing.

The present site's material has high silica. For this reason this is not useful for cement. The

silica is above 16% wherein the silica requirement for cement grade is 8-10%. For this reason

these material are used for Napa slabs dressing.

As per National Green Tribunal Judgment pronounced on 13.01.2015, the proponent has

applied to State Level Environmental Appraisal Committee/State level Impact Assessment

Authority of Andhra Pradesh to obtain Environment Clearance.

2.4 Demand and supply

There is huge demand since the mineral is used extensively in construction sector and

dressing of Napaslabs. This project will help in reducing the Demand-Supply gap in the area.

2.5 Domestic/ Export Markets

The material is used in the domestic market and in there is no scope for exporting the

material.

2.6 Employment Generation

Open cast semi mechanized mining is going to be used except for transport. About total 21

workers are going to be engaged for at least 250 days in a year for loading Napaslabs Quarry

in to trucks / tractors/ tippers. It will provide indirect employment to several workers in the

area. The occupation of the local inhabitants in surrounding villages of the mine area is

Agriculture. The mining activity in this belt will benefit the locals both directly and

indirectly. The directly beneficiaries will be those who get employed in the mines as skilled



4

and unskilled workers. In the long run a lot of social goods are expected in the comparatively

backward area when the inhabitants will be able to send their children to school.

Mine Lease Area



6

3.4.1 Topography

The lease area is on ground level. The area is devoid of any forest or tree cover. It comprises

shrubs only. The lowest contour is 19 m and highest contour is 21 m in topo plan. The topo-

relief of the area is 2 m. The general direction of ground water flow is towards SE. The areas

of Guntur, Paland and Sattenapalle taluks form a part of the Krishna River Basin. The height

of water table ranges from 10m above m.s.l. In the SE i.e., adjacent to Bay of Bengal, up to as

high as 200m in the upland areas in parts of Paland and Vinukonda taluks. The quarry lease

applied area is surrounded by numerous water bodies. The areas around are agricultural lands

at a distance of 0.5 km W.

3.4.2 Regional Geology

Major part of the district is a pedi plain interspersed with residual hills. The Srisailam Plateau

occupies Western part. The Eastern part is a deltaic plain, having a vast stretch of outwash

deposits with paleochannels of Krishna River. The area fringing the coast constitutes a strand

plain. The prominent peaks are Swanukonda (605m) and Kakirlakonda (590m). The

important rivers are Krishna and its tributaries viz., Munneru, Chandravanka and Naguleru

which drain the area in a southeasterly direction.

The district consists of an array of rock formations ranging in age from Archean to Recent.

The Archeans consist of Khondalite and Chamockite Groups of Eastern Ghats Supergroup

and the rocks of the Peninsular Gneissic Complex, comprising granitoids and granitic

gneisses, having 18 wide variations in chemical composition and tectonic environment. The

granitoids and gneisses are intruded by a number of gabbro, norite and doleritc dykes.

Uncomfortably overlying the above rocks the Proterozoic sediments of Cuddapah Supergroup

and Kurnool Group occurs. The Upper Gondwanas of Carboniferous to Cretaceous age occur

as isolated patches spouting through the flood plain deposits. Unconsolidated to semi

consolidated deltaic deposits of Quaternary age are confined to the coastal tracts towards

eastern and southeastern parts.

3.4.3 Exploration:

The quarry is a running quarry. The proposed quarry is surrounded by active Napaslabs

quarries that are already working. The Napaslabs Quarry was excavated for Napaslabs

dressing and converting into chips for construction purpose. The rate of recovery is 80%

with 20% waste.

This quarry has been running previously. As the EC is needed to be obtained as per the NGT

orders, the process is initiated. As per the process a part of submitted documents is the quarry

plan. The mine has been developed much before this document submission. Therefore any

new development is not envisaged. The area has been surveyed and a Surface Geological

Plan was prepared on the scale of 1: 2000 with lowest contour is 19 m and highest contour is

21 for an extent of 0.979 ha and is enclosed in Plate.

The Geological Sections were drawn across the deposit at regular interval on the scale of 1:

2000 scale showing the geology and categorization of reserves.



7

3.4.4 Reserves

The calculation of reserves of prospect, deposit and mine is done at every stage, right from

preliminary to last stage of exploration and mining.

Any scientific work was not done until now. The reserves assumed and established are only a

rough estimate. However the surrounding quarries that are already working are extending to

proven depths of 20 to 30 m. It is a land surface deposit at ground level within the quarry

lease area (lowest contour is 19 m and highest contour is 21 m). The surface of sheet rock is

wavy and irregular.

A total of 12000 Tons of Napaslabs Quarry will be excavated during next five years.

The reserves are estimated by the Cross sectional Method. Section wise calculation of

Napaslabs Quarry reserves is given in the below table:

Three Cross Sections (A-A’ to C-C’) are drawn perpendicular to the slope direction for

profile purpose.

3.5 Project Description with process details

3.5.1 Method of Mining

Presently, the quarrying is with semi-mechanized method by using, excavators, tippers,

jackhammers and by using low explosives. The separation of blocks from the mother rock

will be carried out by drilling and blasting, excavation will be done by the machinery. The

Napaslabs Quarry in the quarry lease area is exposed on the surface with sheet. The area

proposed for excavation is drilled with jackhammers to depths of 3.1 m including sub-grade,

to obtain 3 m bench height. As this is an existing quarry benches are already formed.

Primary block will be cut into secondary blocks by jack hammer drilling and wedge cutting

and this block will be dislodged from in-situ position by an excavator.

The holes are charged with low explosive cartridge like gun powder and non- detonators for

smooth blasting. The proponent is utilizing the services of a Form-22 holder from whom the

low explosive like Gunpowder and other accessories are taken. After removal of weathered

top layer, the sheet will be subjected to splinter into 300 mm sized and transported to the

crusher units for crushing to the sizes of 5 mm, sized chips and < 100 mesh powder. Thus the

commercial chips are produced. No solid waste is anticipated for Napaslabs Quarry quarry.

5. PLANNING BRIEF

5.1 Planning Concept

It is proposed to produce total of 3000 Tons per Annum of Napaslabs Quarry from the

proposed mining lease. The quarry is a running quarry with depth of 3 m. The adjoining

mines are working mines of Napaslabs.

5.2 Population projection

The project will employ mostly workers from nearby villages. About 21 persons will be

employed as workers for this proposed mine. There will not be any increase in population due

to the project.

5.3 Land use planning

The project is located in 0.979hectares/ 2.42Acres of Government land. There will be change

in land use as the Napaslabs Quarry mine will be excavated. An extent of about 9790 Sq. m

area will be sliced down during next five years to a depth of 5 m.

5.4 Assessment of Infrastructure Demand (Physical & Social)

On the basis of the preliminary site visit, the infrastructure demand in the villages was

assessed on the basis of need and priority. The assessment will be made in the socio

economic survey and will be submitted at the time of final presentation regarding EC.

5.5 Amenities/Facilities

First aid box and drinking water facility will be available at the site. Rest shelter will be

provided at the site. It is proposed to provide the site services like mines office and other

statutory constructions like rest shelter, first aid, work shed and drinking water as required

near the quarry lease. Drinking water will be supplied to the workers from the bore well

opened in the adjacent quarry site & agricultural fields.

6. PROPOSED INFRASTRUCTURE

6.1 Residential Area (Non Processing Area)

As the local persons will be given employment, no residential area/ housing is proposed

within the mining lease area.

6.2 Green Belt

It is proposed to plant 50 trees in five years by planting 10 trees per Annum. Five trees will

be planted within in the village or haulage road area and five trees in the buffer zone. Trees of

mango, neem and peepal would be planted.

6.3 Water Management



11

The total water requirement is 2.5 KLD. There are no chances for changes in quality of

surface water or ground water the quarry operations will be carried out on the rocky terrain.

Hence neither the ground water table nor the general surface drainage pattern is affected. No

water will be discharged from the quarry.

Following measures shall be taken:

It shall be ensured that silt discharged from the mine area will be minimized to the

utmost extent.

Pumps of adequate capacity shall be installed to lift the accumulated rain water.

It shall be ensured that good quality potable water is provided for drinking purposes.

Good sanitation facilities (toilets with septic tank followed by soak pits) shall be

provided and maintained for good hygienic conditions.

The spillages form fuelling of machinery shall be avoided and in case of any spillage

the same shall be handled properly. Likewise the spent lubricating oils etc., shall be

safely collected and properly disposed off.

6.4 Sewerage System

Arrangements for disposal in to soak pit outside the river bank will be made.

6.5 Industrial Waste Management

Not applicable.

6.6 Solid Waste management

During mining in next 5 years a total of 3000 Tons of waste will be generated and dumped at

the temporary dumping yard, on an average of 600 Tons per annum.

The waste rock generated will be temporarily dumped in the South block of the quarry lease

area covering an area of 1369 m2

with an average height of 3 m with 45o slope angle. A

retaining wall will be constructed around the dump for preventing the slanting of waste rock.

7. REHABILITATION AND RESETTLEMENT (R&R) PLAN

An extent of about 9790 Sq. m area will be sliced down during next four years to a depth of 5

m. The proposal for reclamation of land affected by mining activity will be done at the end of

mining lease. No reclamation is proposed in the first five years period because, the mining

will be continued to further depths and reclamation will be possible only after completion of

mining up to the proposed depths.

Reclamation and rehabilitation of the lands affected by mining will be done by back filling,

soil amelioration and afforestation. This will be taken up on need basis before the conclusion

of mining operations. Reclamation of the affected land includes back filling, drainage

development, spreading and fertilization of soil, leveling and re-vegetation etc. Care will be

taken to implement the said factors.
