Answer given by the minister



MINISTER OF STATE (INDEPENDENT CHARGE) IN THE MINISTRY OF COAL, POWER , NEW AND RENEWABLE ENERGY AND MINES (SHRI PIYUSH GOYAL)


(a)-(b) : Yes Madam. Coal is washed in coal washeries to reduce ash content so that there is less fugitive emission in the air. Coal India Limited (CIL) has planned to set up 15 washeries in its various subsidiaries to reduce the ash content in the coal.

(c): The number of coal washeries currently in operation in CIL is 15 with a total throughput capacity of 36.80 Mty, out of which 12 are coking coal washeries with capacity of 23.30 Mty, and 3 are Non-coking coal washeries with Capacity 13.50 Mty. The details are being given in the table below :-

The amount of coal above G-10 grade washed in washeries of CIL subsidiaries during the year 2016-17 from April 2016 till Feb’2017 is 213369.15 tonnes.

(d): CIL has planned to set up 15 Coal washeries in the first phase having a total capacity of 94.1 Mty, out of which 6 washeries are for Coking Coal with total capacity of 18.6 Mty and the remaining 9 are for Non-coking coal with total capacity 75.5 Mty.
In addition to the above, 5 more new washeries (1 in BCCL & 4 in CCL) and 2 de-shaling Plants (in BCCL) for coking coal are being envisaged to augment the supply of washed metallurgical coal. Further 5 existing coking coal washeries (in BCCL) are planned to be renovated to improve capacity utilization. Overall details of the 27 washeries are furnished in the table below:

(e): Washeries are set up to control the ash content of coal to reduce air pollution. However, during various operations in coal washeries, a lot of particulate matters and gaseous pollutants are generated causing an air pollution problem in the area. Hoppers of the crushing units and washery units are fitted with high efficiency bag filters and mist spray water sprinkling system installed and operated effectively at all times of operation to check fugitive emissions from crushing operations, transfer points of closed belt conveyor systems and transportation roads.

Three-tier green belt is being developed along the washery boundary and along transfer and loading points and railway siding to mitigate / check dust pollution. All the washeries have been made Zero discharge. The same water is recycled again and again in the main process of the washery.
