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
SAKTHI MINES & MINERALS

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

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.

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.

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.

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.
