Main reasons adversely affecting coal
production in the country are delays in land acquisition and Rehabilitation and
Resettlement (R&R) issues; environmental and forestry clearances; lack of
rail evacuation facilities and poor law & Order situation in some areas. Coal
companies are adopting appropriate technologies for extraction of coal from
their mines depending upon specific geo-mining conditions of the area.
is a continuous effort to upgrade the technology adopted by coal companies to
achieve high production / productivity and safety. At the behest of Government
of India, CIL has recently appointed an International Reputed Consultant to
study and submit a report on modernization/mechanization of mines of CIL.
Besides, in Opencast
mining, CIL is adopting the contemporary Technology using draglines,
shovel-dumper combination, surface miners etc. as per the site specific
geo-mining conditions. Mega opencast projects are now being planned with higher
size of equipments. Operators Independent Truck Despatch System (OITDS) has
also been introduced in several opencast mines for further improvement in
In case of underground mines, intermediate technologies deploying Load Haul Dumpers/ Side Discharge
Loaders (LHD/SDLs) have been introduced almost in all the mines of CIL. However
some manual operations still exist. Continuous Miner Technology has already
been introduced successfully in a few underground mines where geo-technical
conditions are amenable.
In addition to the above,
for adopting state of art technology in the underground mines, the following
steps are taken/ proposed to be taken in Coal India Limited (CIL):
planning an underground mine, the preference is given to mass production
technology by deployment of Continuous Miners (CMs), Longwall
Technology. In case it is not feasible, mine is planned
with Side Discharged Loaders (SDL)/ Load Haul Dumpers (LHDs).
extract coal from underlying coal seams in the highwall
of a surface Coal Mine, which has reached the final highwall
position due to un-economical stripping ratio or due to local surface
constraints which limits further surface mining operation, highwall
mining method is also adopted.
mine is presently being planned with manual mining methods. Manual mines are being phased out/converted
into intermediate technology mines i.e. with SDL/LHDs.
increasing the mechanization in the underground mines, it is planned to
increase the number of coal wining machines substantially, especially Continues
present total 7 numbers of Continuous mines are operating in 7 underground
mines of Coal India Limited having total planned capacity of 2.835 Mty. 20 more underground mines have been identified where
total 25 continuous miners are envisaged to be introduced in near future with
likely capacity addition of 11.51 Mty.
orders have already been issued to Mine Developer Operators (MDOs) to operate 5
(five) mines (Jhanjra in ECL, Kapuria,
Moonidih (both XV & XVI seam), and Muraidih in BCCL) by longwall
technology. Likely capacity addition from these mines is 8.9 Mty.
