Coal India Ltd (CIL), invites offers/bids through e-tendering from academic/research institutions and/or consultancy firms/organisations of India or abroad for providing consultancy services for ‘study on underground coal mining in CIL – problems, potential, technology, modernisation, production and safety’,” according to a tender document dated November 2, 2015.
A consultant will advise Coal India to ramp up production from underground mines as the PSU prepares to meet its ambitious target of producing 1 billion tonnes of coal by 2020.
The Central Mine Planning and Design Institute, the research and exploration arm of Coal India, has invited bids from consultants to prepare a study on underground mines.
The tender comes at a time the PSU coal miner is gearing up to meet the 1-billion-tonne output target by 2020.
In a reply to a question in the Lok Sabha, coal and power minister Piyush Goyal said underground mining was practised at a depth of 300 metres and almost all underground mines were less productive and making losses. Moreover, some of the unsafe legacy mines are being converted into open cast mines to meet demand.
He said the scope to raise production from underground mines was limited on account of difficult geo-mining conditions, non-availability of large size deposits to adopt mass production technologies and inadequate experience in the mechanisation of mines.
Other major constraints include the lack of appropriate technologies to mine coal from thick and steep inclines and multiple seams, heavy pumping out of water and adverse roof conditions.
