Sl.No.


ii) Short term (5 years) as well as long term (20Years) plans are always kept updated as per the

Guide lines issued by A.P., France, providing for

overall Environment management

considerations.

B)

Peripheral barrier with green belt

around mining area:

More than 7.5 mtr. width of peripheral barrier left all along the

Mined out area with green belt developed over it. This green belt isdeveloped/ maintained 500M ahead of Mining operation.

C) Garland drains around the mining

area:

Garland drains are being maintained ahead of mining operation to

drain surface run-off water to the valley following natural gradient.

D) Drainage control within the mining

area

Movement of mine faces are being carried out systematically as per

mine plan following the contour lines such that the faces have self

draining slopes. Rain water in the mines from these self draining

slopes are being collected in two sumps within the mined out area.Water from the sumps mostly percolates down through thick clay

layer which acts as a filtration bed. Three barriers/bunds are

provided to arrest / restrict flow from sumps at mined out area .

2.

A)

Mine Rehabilitation :

Preservation & use of Top Soil

i) During initial mining activities about 1.0 lakhtonnes of top soil was excavated and preserved

separately which was used in the back-filled

areas, Overburden dumps, adjacent slopes ,

nursery development and afforestation activitiesby the end of year 1989-90.

ii) At present top soil is being excavated separatelyand directly used in the reclamation area.

B) Systematic development of minedout area for land restoration:

Mining activities are carried out systematically as per a long term/short term mining plan. Overburden & Top soil stripped ahead of

bauxite mining faces are dumped in backfilled/ Mined out area

created continuously as the mining proceeds with complete

exploitation of Bauxite. Dumped lateratic overburden is levelled

before putting topsoil which also subsequently leveled/ dressed toprepare the reclaimed land ready / suitable for plantation with

necessary provision of benches and terraces. As such back filled

area development/ land reclamation is an integral part of mining

process and goes hand in hand with bauxite mining. Total areareclaimed so far, following the said procedure is 199 Hects.


18/35

Sl.

No.


C)

Land development with forestry &

water basin :

As explained above , the backfilled area is developed with proper

benching and drainage system to maintain slope stability. As such,

the mined out area is totally reclaimed with backfilling, plantation

and water basins at strategic points for ensuring proper drainageAfforestation is carried out with selected forest and fruit bearing

species in this back-filled areas. Till date total 199 hects of mined

out area reclaimed, has been planted with 4,92, 200 nos of trees..

3. Treatment of Over-burden and soil

dumps.

At present total overburden(laterite & top soil) removed is being

used for backfilling in mined out area obviating needs for further

creation of overburden dumps. This process has started since the

year 1989-90 .

All soil dumps of construction phase have been suitably stabilised

by undertaking necessary soil conservation measures .Further these

areas with plantation done , have now been covered with good

vegetation, where growth of vegetation is satisfactory.

4. Dust Suppression Dust suppression in the mining area is being carried out by watersprinkling using mobile tankers. In addition to this an auto

sprinkling system has been installed/ maintained all along the

central /Main haul road .

All Drilling machines are provided with efficient dust extractors

and or wet drilling arrangements. Dust extractors and hoods are alsoprovided at transfer points in Crushing and Conveying System apart

from provision of Covers all along the Conveyor System (14.6 km

long) to restrict the dispersion of dust. In the crusher house ,an

efficient dry fog system is provided for suppression of dust at ROMhopper and Transfer points. Employees are provided with personal

dust protection equipment like nose masks, wherever necessary.

5. Control of Noise & Vibration Equipment/ machineries have been selected with least noise &

vibration level and periodic surveys have shown them to be within

limit of TLVs. With the multiple face working, the equipment are

scattered over a vast area, there-by reducing any concentration ofnoise and vibration level exceeding TLV in any particular area.

Operators cabins in different equipment/machineries and at drive

house/crusher have been completely enclosed to reduce noise level.

Vibrations due to blasting is also kept to a minimum by adopting awell designed blasting pattern with sequential blasting by use of

delay detonators or by use of NONEL. As per the study conductedby M/s ISM, Dhanbad & M/S CMRI , the blast vibration falls to an

imperciable limit within a distance of 50-60 metres on hill slope.

Employees are provided with personal ear protective equipmentslike earplug, earmuff wherever necessary.


19/35

Sl.No.


6Sewage/Waste Water treatmentsystem

Adequate sewage systems are provided in the mining complexwhich are being checked regularly. Effluents from the Mechanical

Workshop area is being chanelized through well-designed oil-water

separation tank where oil is collected and the clear water is recycled

for washing of equipments & dust suppression purpose. Also there

is a canteen waste water disposal system designed, constructed andmaintained for environmental friendliness.

7. Plantation activities : Till date we have completed plantation of about 1050 hects within

Mininig Lease hold areas with 27,73,769 nos. of trees of more than70 diff. Species. This includes experimental plantation,

beautification of areas, development of lawns etc.

Development of Nursery and experimental plantation : Mine has

its own nursery and in this high altitude nursery experiments are

being carried out for testing the survibility & adoptability ofvarious types of forest & economical species.

8. Monitoring activities: Monitoring of various aspects of environmental Management Plan

by our multi-disciplinary team & confirmation by various

professional agencies leads to conclude that implementation ofEMP is going on very satisfactorily bringing continuous

improvement of environment.

The followings are the latest observations taken during the period

from October 2011 to March 2012.
