scale tree plantation in and around the mining
The success in land reclamation of mines spoils and
afforestation has been very significant and
overwhelming in places like Ashoka, Piparwar etc.
The mined out areas or the de-coaled area is
refilled with overburden at places where no mining
is required in future. The OB fills and dumps are
not very conducive to growth of plants, since these
sites do not contain adequate plant nutrients. The
dumped soil is improved in stages through modern
techniques to bring back its fertility and the
horticultural operations are carried out by adding
nutrients, like organic, inorganic and
Bio-reclamation of degraded mined areas of more than
4300 Ha (since 1992) of different types of land like
OB dumps, subsided areas, mined out areas, colonies,
The total plantation done in CCL since 1992 is more
than 66 lakhs, covering all the mining areas of CCL.
During last 7 years the plantation done is more than
34 lakhs which itself is a positive indication of
improvement in bio-diversity and environment.

Regular air, water
and noise monitoring by CMPDI to keep a check on the
adverse parameters, if any.
All the mines / washeries of CCL are being monitored
on regular basis by CMPDI. Every quarter there are
about 175 Ambient Air Quality sampling, 185 water
quality sampling and 150 noise survey being done by
CMPDI. In case of any, adverse parameters reported
immediate action is taken by the areas / projects
Remote Sensing Survey for analysis for land use
improvement in large mines.
The large producing mines are being monitored for
land reclamation by Remote Sensing techniques
through CMPDI on annual basis. The mines like
Piparwar and Ashoka are being monitored since last 4
years and it can be seen from the analysis that the
reclamation / a forestation has increased from 198
Ha to 225 ha ie. an increase of about 14% in 2
years. The mines being monitored are Ashoka,
Piparwar, KDH, Parej and Rajrappa OCPs.

Provision for water sprinkling by 28 KL tankers In
all its Open cast mines haul roads and others.
The total no of mobile water sprinklers in CCL
are 44 of capacity 28KL each and two 60 KL each.
Besides these there are 4 converted water sprinklers
of 28 KL. In addition to these the projects are
enhancing the water sprinkling through engagement of
contractual water tankers
Filling of abandoned mine voids by fly ash and
CCL has undertaken filling of some of its
abandoned mine voids by fly ash from BTPS, CTPS,
BPSCL, DLF etc.
Provision of dust extractors and wet drilling in
all mines / units.
CCL is having a total of 116 drill machines wherein
the NVE dust extractors are fitted in all the
machines and are working. In order to improve the
environment further CCL has planned to replace this
with the provision of wet drilling in all the drill
machines. At present CCL has already converted 4
drilling m/c with wet drilling arrangement and 6 is
in progress and the is expected to be completed very
soon. CCL has planned to convert all the drilling M/cs
with wet drilling arrangement within 6 months in a
type of nozzle, water spray systems have been
installed in CHPs, Feeder breakers, Coal transfer
points, crushers etc. of mines and Washeries.
Sprinkler at RCM siding of Piparwar Area of CCL
Controlled blasting / planning of colonies /
habitation away from the mines as far as possible.
CCL is using NONEL type detonators for controlled
blasting and minimum impact of dust and vibration.
Provision of closed water recirculation
arrangement in all washeries.
The closed water recirculation system has stopped
the effluent discharge from the washeries. Besides
this arrangements of water sprinkling in coal
transfer points, good housekeeping and plantation
etc is being done in the washeries for overall
Pollution control through effluent treatment plants
/ domestic treatment plants / oil grease traps etc.
There are 17 mines having ETPs (Oil & Grease
Traps)and 4 mines are having Sewage Treatment

There are six mines equipped with Rain Water
Harvesting (RWH) facilities

Treatment Plants in areas for providing clean
having a total of 12 water treatment plants spread
over the mining area. There are 77 pressure filters
plants and 75 deep bore holes for clean supply of
Development of water bodies / lagoons in mining
areas for sedimentation of fines as well for
improvement of aquatic life.
Piparwar OCP of CCL
and one washery are having ISO 14001 – 2004
Environmental Management System and CCL is underway
for obtaining certification for 4 more mines /
The mines already having ISO Certification
Parej East OCP
North Urimari OCP
Piparwar CPP washery
Regional Repair Shops (RRS)(Workshops) / Hospital
having ISO 9001-2008 certification are:
It is expected that by the year end the ISO
certification of further 4 mines (given below) will
has planned that by 2013-14 all the mines producing
more than 1 MT, all the washeries and Central
Hospital, Naisarai will be ISO 9001:2008 & ISO
14001:2004 certified units.
