highwall mining process in india

Highwall Mining in India Springer

1 Introduction Coal renders more than half of India's power generation. More than half of the country’s 223.3 gigawatt installed capacity is produced from coal [1]. India is the world’s third-largest producer of coal. It has produced 557.5 million tonnes of In USA, highwall mining contributes about 4.0 % share of total coal production. In India, the highwall mining is in the nascent stage. So far only two highwall mining are being Highwall Mining in India SpringerLink

An Investigation on Optimal and Safe Design of Highwall Mining

When the stripping ratio of surface mining operations loses profitability, the highwall mining method can be applied to recover the residual coal reserves beneath the final highwall (Fig. 1).In the most general sense, highwall mining is the process of extracting coal reserves from the base of an exposed highwall left by the previous surface mining.
