The first highwall project of Eastern Coalfields Limited at Nimcha Colliery, Satgram Area, Paschim Bardhaman, West Bengal, is commissioned. This project will assist ECL in producing 0.5 million tonnes of coal per year.
Highwall mining is a mining method for attaining additional coal recovery after the economic strip limit is reached in surface mining.
Highwall mining equipment is remotely deployed in openings beneath the final highwall, and workers do not need to go inside the working face.
This technology provides an economical way to extract coal reserves locked up in the high wall.
