3. NEED FOR THE PROJECT AND ITS IMPORTANCE

Silica sand forms the major ingredient among natural raw materials required for

glass making and it is also used in foundry, ferro-silica alloy and cement industries

besides being used in many other industries like ceramic, fertilizer, abrasives, chemical,

coal washery, electrode, paint, rubber, textile, water filtration, construction etc. The

natural silica sand is preferred in glass industries, but in cases when silica deposits are

located far away, crushed quartz is used. The proposed Silica Sand mine for mining high

grade glass industry suitable sand. The general mining method in is by manual cum

opencast Manual method.

There is a growing demand of quality silica sand mineral in the foundry as well as

glass industries. Availability of good quality silica sand is limited. Therefore marginal and



5 JANUARY 2018

low grade silica sand needs to be beneficiated for making it useable in the industries.

The lessee has network for supply of the silica sand to the foundry persons. Therefore

the purpose of the project is to excavate and trade silica sand to the customers, mainly

comprising of glass industries, while taking care for safety of persons and machines

deployed, and care for the environment. The Mines in the present area are supplying the

material to glass industries.

As per EIA notification 2006 project proponent is submitting the proposal to get

Environmental Clearance for Silica Sand mining with production capacity of 1439

Tonnes/Year from Environmental Appraisal Committee constituted by MoEFCC, GOI for

the purpose of grant of Environmental clearance.

FIGURE 2 - KEY PLAN OF VANDUVANCHERI Mine Lease Area

The Silica Sand extracted with the help of machineries for digging, excavation, Alluvial

sand and mine reject. All operations of mining, including excavation, loading &

transportation on single shift basis shall form the complete mining operation. The silica

sand is loose and free flowing. There is no need of any blasting or drilling in the

projected operations.

NEED FOR THE PROJECT AND ITS IMPORTANCE TO THE COUNTRY AND OR

REGION.

The production of silica sand at 2,283 thousand tonnes in 2009 – 10 decreased by

about 19% over that of the previous year due to lack of demand from cement plants and

labour problems. Andhra Pradesh the major producing state reported decrease of about

28% in comparison with the previous year due to of request labour problems. During the

year under review, there were 133 reporting mines as against 138 in the preceding year.

Besides, the production of silica sand was also reported as an associated mineral by four

mines during the year. Ten principal producers accounted for about 54% of the total



7 JANUARY 2018

production. The share of public sector in the total production was 5% in 2009-10 as

against 1% in the preceding year. Andhra Pradesh, the leading producing state

accounted for 39% of the total production during the year followed by Gujarat (17%),

Rajasthan (14%), Maharashtra (13%), Uttar Pradesh (7%), Jharkhand and Karnataka

(4%each). The remaining two percent productions was the contribution of Kerala, Odisha

and Tamil Nadu. About 62% of the total production of silica sand was contributed by 15

silica sand mine sand two associated mines, each mine producing more than 50

thousand tonnes annually and about 33% by 56 silica sand mines and one associated

mine, each producing five thousand to fifty thous and tonnes. The remaining 5% of the

output was contributed by 62 silica sand mine sand one associated mine, each producing

less than 5000 tonnes annually. Mine-head stocks of silica sand at the end of 2009-10

were 3,260 thousand tonnes as against of 1,280 thousand tonnes in the beginning of the

year. The average daily employment of labourers in 2009-10 was 2,401 as against 2,257

in the previous year. Domestic prices of silica sand are furnished in the General Review

on Prices. (Source: Indian Minerals Yearbook 2011 (Part- II) by Indian Bureau of Mines.)

5. DEMAND SUPPLY GAP

There is a demand of Silica Sand and is ever growing with the growth of industrial

sector in the country. The requirement of the mineral is always found high in adjoining

areas. Geological processes have occasionally deposited sands that are composed of

almost 100% quartz grains. These deposits have been identified and produced as

sources of high purity silica sand. These sands are used in the glassmaking industry

projects.

6. INDIGENOUS PRODUCTION

Presently there are no imports of this sand. The indigenous production is sufficient for

the Indian market. There is established export market for this material. Most of the

material is exported from Mundra port and Mumbai port. There are possibilities of export

to China, Bangladesh, and Korea etc.

7. EXPORT POSSIBILITY

Most of the material is exported from Mundra port and Mumbai port. There are

possibilities of export to China, Bangladesh, and Korea etc.

a. GEOLOGY OF THE AREA :

This area is made up sediments of Holocene age (10,000 Years Old) covered by

the Alluvial sands. The formations are rarely exposed, excepting along the

embankments of tanks, in which the silica sand abounds. The geological succession in

the region may be summaried as follows :

Recent Alluvial Sands

Archaean Granites and gneisses

The archaean granites and gneisses which form the crystalline basement have

been met with at a depth of about 900 m below the sediments in some of the bore holes

put down by the oil and natural gas commission drilled for oil in the surrounding area.

The Holocene sequence of Silica Sands over lie the Vanduvancheri sandstones which

seem to have formed their provenance.

The Silica Sands form a persistent horizon and are overlain by light brown

coloured, fine grained windblown sands simulating the teri-sands along the Tamilnadu

Coast. They are about a metre in thickness and form an extensive cover. The silica

sand are generally of greyish white colour. They made also carry at places shells of

gastropods and oysters, suggestive of its margine origin. The sands are underlain by a

black clay, which is sticky in nature. The following is a generalized section of the

different horizons observed in the area.

Alluvial Sand : 0.5m (average)

v) Project description with process details (a schematic diagram/ flow chart

showing the project layout, components of the project etc. should be given).

a. Physiography

The Mining Lease area is approximately at N 10° 25’ 44.41” latitude and at E 79°

39’ 50.34” longitude and is represented by Topo Sheet No.58 N/11 of Survey of India.

b. Regional Geology

Water table is noticed at a depth of 10m from the surface in the adjacent open wells of

the area.

This area is made up sediments of Holocene age (10,000 Years Old) covered by

the Alluvial sands. The formations are rarely exposed, excepting along the

embankments of tanks, in which the silica sand abounds.

The geological succession in the region may be summaried as follows :

The Holocene sequence of Silica Sands over lie the Vanduvancheri sandstones which

seem to have formed their provenance.

The Silica Sands form a persistent horizon and are overlain by light brown

coloured, fine grained windblown sands simulating the teri-sands along the Tamilnadu

Coast. They are about a metre in thickness and form an extensive cover. The silica

sand are generally of greyish white colour. They made also carry at places shells of

gastropods and oystars, suggestive of its margined origin. The sands are underlain by

black clay, which is sticky in nature. The following is a generalized section of the

different horizons observed in the area.

Alluvial Sand : 0.5m (average)

White Silica Sand : 4.5m

Alluvial Sand:

It forms an extensive blanket of thickness with light brownish colour and grain

size. The sandy surface is of adulatory nature and appears to represent a fill of the

uneven surface by Alluvial sand from the shore and may represent sand dunes of

migratory and recent origin. The well rounded nature of the sand grains is due to

continual wave action during formation as coastal sand beds and transported under

Aeolian influences.

Silica Sand:

The Silica Sand, with an average thickness of 5.0m is of light grey colour and

yellow at the base in some sections. It is of medium to coarse grain size forming a good

aquifer. Presumably storing the rain water and to some extent of the water from the

Cauvery Canal System passing through the area. The greyish colour of the sand may be

due to moisture since it becomes white on drying.

The upper 0.5m zone of the 3.0m thick sand is of medium grain size, while the

lower zone is of coarse size of 2 to 3 mm indicative of some type of graded bedding

during is deposition. The coarse particles are colourless and somewhat angular quartz,

suggestive of their immature nature due to limited transportation from their source. The

yellow colour observed is about 0.3m thickness of the basal section of the sand could be

due to infiltration of ferruginous material. Shells of gastropods and oyster are

conspicuous at the base of the sands in some places.

Black Clay :

The Black Clays underlying the sand are somewhat semi-plastic and form a good

impervious zone and prevents loss of ground water. This is a very extensive horizon and

seems to have been formed under reducing conditions in a deep seated depositional

environment during the evolution of the (Holocene) sedimentary sequence. The nodules

of canker dispersed in the clays are presumably due to capillary action before the

deposition of the sands.



21 JANUARY 2018

i. Method of Mining

Open Cast manual method of mining is adopted for exploitation of Silica Sand

from this area. The mine worked manually and “B” category mines. The silica sand is

loose and free flowing. There is no need of any blasting or drilling in the projected

operations. Thus the use of explosives and calculation of powder factor does not arise.

Only tippers will be used. Loading will be done manually by hand shovels.

BENCH DESIGN PARAMETERS:

Silica Sand benches will be formed to a height of 2.5m and width not less than

2.5m for movement of machineries and slope shall not be more than 60º for waste

bench and therefore the working face is designed to a height of 2.5m and the width not

less than 2.0 - 2.5m and the working slope will be vertical, however the final slope will

be 45º while abutting the ultimate pit limit.. Construction of parapet as a fencing around

such ultimate pit limit on top of opencast workings will be arranged to safeguard the

mine from inadvertent entry and hazards.

11. PLANNING BRIEF

i) Planning Concept (type of Industries, facilities, transportation etc) Town and

country planning/Development authority Classification.

Open Cast manual method of mining is adopted for exploitation of Silica Sand from this

area. Transportation and commodities infrastructure facilities are locally available near

the project site. The mining of Silica Sand is transported from mine head to processing

plant by tippers.



27 JANUARY 2018

Transportation

The mining of Silica Sand is transported from mine head to processing by tippers. The

entire mine out mineral is being sold in domestic market and to industries nearby the

lease area.

ii) Population Projection

There are few villages located in the 5 km radius of mining site and approximate

distance and population are given below.

TABLE 14 Total Populations

Basic human welfare needs such as schools, communications facilities and commercial

centers etc are available at Thiruthuraipoondi located at a distance of 12.0 km from the

North side of the mining area.

iii) Land use planning (breakup along with green belt etc.)

Green belt will be developed in the safety zone area etc, and at all possible places. Local

trees like Coconut, Casuarinas, Eucalyptus, Neem, acacia, Tamarind etc will be planted

along the 7.5m boundary barrier of the lease area and avenues as well as over Non-

active dumps at a rate of 10 trees per annum with interval 5m in between. The rate of

survival expected to be 80% in this area.

iv). Assessment of Infrastructure Demand (physical & social).

The existing roads facilities are already available which shall be used and maintained.

The labors requires to operate the mine is drawn from the nearest villages.

V) Amenities/Facilities.

Associated buildings like mine office, store, First Aid Station, rest shelter, Toilets, etc. as

per Mine Rules 1960 are available within the leasehold area.

12. PROPOSED INFRASTRUCTURE

i) Industrial area (processing area).

Mineral Processing operation only hand sorting of ore is involved

ii) Residential Area (Non processing Area).

No Residential area are envisaged

iii) Green Belt.

7.5 m safety distance on the southern side is selected for green belt development by

planting and maintaining native species of Coconut, Casuarinas, Eucalyptus, Neem,

acacia, Tamarind etc will be planted along the 7.5m boundary barrier of the lease area

and avenues as well as over Non- active dumps at a rate of 10 trees per annum with

interval 5m.

iv) Social Infrastructure.

Social infrastructure like primary school at Vanduvancheri secondary schools, banks and

hospitals are located at nearest town Thiruthuraipoondi. Since the mine site is located

near to Nagapattinam City and it has all the essential facilities like school, hospitals and

medical facilities etc and also well connected with roadways.

v) Connectivity (Traffic and Transportation Road/Rail/Metro/Water ways etc.)

Adequate road facility is available from the mine lease area.

vi) Drinking Water management (Source & Supply of water)

Drinking water is available from well & tube well near the proposed site which is potable

and will fulfill the requirement of drinking water at site. Source – Borewell.

vii) Sewerage System

The sewage generated in the mine lease area is treated through septic tank followed by

soak pit.

viii) Industrial Waste Management.

No industrial waste will be generated from the project.



29 JANUARY 2018

ix) Solid Waste Management.

The proposed Silica Sand mine anticipated waste during the present scheme period is

about 639 Tonnes (Total waste).

x) Power Requirement & Supply / Source.

As already mentioned the simple methods adopted and the limited scale of activities

involved in Silica Sand dimensional stone mining does not require high- tension electric

power. The mining work is restricted to one general shift during daytime only. No

electricity is needed for Mine operations etc as mainly diesel operated mining machinery

are used for Mining However, the power requirement of the administrative buildings,

roads etc can be met from state grid. The silica sand is loose and free flowing. There is

no need of any blasting or drilling in the projected operations. Thus the use of explosives

and calculation of powder factor does not arise.

13. REHABILITATION AND RESETTLEMENT (R & R) PLAN

i) Policy to be adopted (central/state) in respect of the project affected person

including home oustees, land oustees and landless laborers (a brief outline to

be given.)

There is no rehabilitation and resettlement is involved. The deployed labors will be

insured as per government norms.

14. PROJECT SCHEDULE & COST ESTIMATES

The total project cost is Rs. 13,50,000/- for deployment of machinery and creation of

infrastructural facilities like approach road, Mine office / Workers Shed, First Aid Room

etc.., including electrifications and water supply.

15. ANALYSIS OF PROPOSAL (FINAL RECOMMENDATIONS)

i) Financial and social benefits with special emphasis on the benefit to the local

people including tribal population, if any, in the area.

The project is been giving direct and indirect benefits to the peoples in around the

project site, beside the government. As the Silica Sand mining operations in the

proposed mine will employ about 18 persons directly and on indirect employment several

workers in the nearby area for loading silica sand in to trucks , tractors and tippers, etc,

which will provide a great fillip for raising income levels and standards of living in the

area.



30 JANUARY 2018

The socio- Economic conditions of the village and distance has enhanced due to the

project, hence, the project should be allowed after considering all the parameters. The

detail furnished in this scheme of mining is based on information provided by the State

Government and the lessee.
