These plants would be set up by its subsidiaries namely Western Coalfields Limited, Central Coalfields Limited, South Eastern Coalfields and Bharat Coking Coal Limited.
The coal behemoth has envisaged processing the overburden rocks for sand production in mines, where OB material contains about 60 per cent sandstone by volume which is harnessed through crushing and processing of OB.
OB to M-Sand initiative of CIL entails facilitating processing of waste overburden in its open cast (OC) mines.
During opencast mining, the overlying soil and rocks are removed as waste to extract coal and the fragmented rock (or OB) is heaped in dumps.
Most of the waste is disposed of at the surface, which occupies considerable land area and requires extensive planning and control to minimize the environmental impact of mining.
To ensure recovery of sand from waste overburden is the best out of waste product, sources said.
The five proposed plants will ensure commercial sale of produced sand, which will generate additional revenue for coal companies, they informed further.
Apart from commercial use, sand produced shall also be consumed for sand stowing in underground mines, thus enhancing safety and conservation, sources said further.
