2.3.Need for the project and its importance to the country or region
Road Metal is a form of mineral, typically produced by mining a suitable rock deposit.
The demand for Road Metalhas increased due to rapid housing development,
industrialization and growth in infrastructure. Due to the State bifurcation there will be
rapid development.
As per National Green Tribunal Judgment pronounced on 13.01.2015, the proponent has
applied to District Level Environmental Appraisal Committee/District level Impact Assessment Authority of Andhra Pradesh to obtain Environment Clearance.
There is huge demand since the material is used extensively in Construction, Building,
Roadways and many other sectors with the increase in infrastructure development. This
project will help in reducing the Demand- Supply gap in the area.
2.4.Demand and Supply
There is huge demand since the material is used extensively in major sectors with the
increase in development. 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 25 workers are going to be engaged for at least 250 days in a year for
loading Road Metal 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 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.

3.5.Project description with process details
3.5.1. Method of estimation of Reserves:
In this method reserves will be estimated considering the surface area of the mine multiplied by average depth of the reserves. In this area max RL is 60 m and Minimum RL is 39 M (BM
& GL). Hence take the difference is 21 M is proved reserves.
As the terrain of the lease area is hilly, hence it is appropriate to consider sectional area method instead of arithmetic method as depth of the reserve is varying in the lease area.
The reserves are considered only on ABM 45m. (GL) It is proved reserves (111)
The Road Metal found to be normal in that area, the deposit is being worked out to a maximum depth of 39 m (up to 39M RL. It is GL) only.
Cross sectional method of estimation of Reserves:
Two Cross Sections (A-A’, B-B’, are drawn perpendicular to the slope direction for profile purpose. The reserves were estimated in cross sectional method of estimation as given below.
Sectional Area, Section Influence, Volume of Geological Reserve x = (Width x Depth) (Sq.m.) Length (m) (Cu. m.)

The proved reserves are calculated up to RL40m for estimation of mineable reserves. But the
UPL is 40m RL.
The recovery of the Road Metalfrom the quarry is 100%.Hence no waste is generated.
Mineable Reserves
Mineable reserves are calculated by deducting the reserves blocked under benches from the total geological reserves. Only proved reserves were considered for calculating the mineable reserves. The details of reserves blocked under benches & safety zone are given in table above
Summary of Road Metal Reserves in (m3)
A. Total Proved Reserves(m3) : 81988

3.5.3. Mineable Reserves
1) Mode of mining recovery factor, Mining loses, processing loses etc Open cost Manual Method of mining with shallow drilling and Blasting. Recovery Factor is 100%. 2) Cut off grade : Not Applicable Ultimate pit limit : 40M
3) Mineral blocked due to presence of /maintenance of benches , barriers inter roads , electrical lines etc., The deposit will be blocked under the 7.5 buffer zone and safety benches as the quarries enclosing the subject area also will be slicing the hill simultaneously in depth ( Present we will proposed to develop the benches for safety parameters).
The internal roads area temporary in nature the follow the suite of benches that will be formed.
No electrical lines are passing over the subject area.
3.5.4. MINING
Method of Mining (Open Cast other than fully Mechanized/Semi Mechanized):
The Road Metalin the Quarry lease applied area is exposed on the surface. Hence, it is proposed to mine the Road Metalby open cast, using semi-mechanized method, by developing the benches of 6 M height with 2 slices of 6 m and 3 M bench width with shallow drilling and blasting. The development of benches will be maintained @ 40 - 600 safety slopes.
Drilling
Drill holes of 6.0 – 3.0 m depth will be drilled in a staggered pattern at 3 m.x 4M interval:
i) Drill hole diameter : 54 mm up to 6.0 m long ii) Depth and inclination of drill hole : Generally drilled vertically in an alignment iii) Explosive type : ANFO+ Booster & detonator Fuse
Production Proposed for the next five years.
It is proposed to produce 39152 cu.m of Road Metal during 5 years plan period with an
average annual production of 7630.4 cum from an area of 6970 M2. Benches of 6M height
and 3m width will be developed during the plan period.
The applicant proposes to take up quarrying operations north west and south west part of the
quarry lease applied area and then continue to move towards western side.
