Suitability study of surface miner in indian coal

This study is limited to the specific geological mining conditions of a specific mine. 2. This study is only applicable to three types of Wirtgen open-pit mines: 2100, 2200, 2500 and 4200, and also applicable to ksm303 and ksm304 of L-T open-pit mines. The cost and output of different types of open pit mines will be different.
