Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler ® surface excavation machines can work where explosives can't, with top-down cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.

Mining with continuous surface miner is one such option. Very recently (06/1999) a Wirtgen 2100 SM Continuous Surface Miners (CSM), has been introduced in one of the Indian surface coalmines, Lakhanpur opencast project of Mahanadi Coalfields Limited (a subsidiary of Coal India Limited), on an experimental basis for excavating coal only.

Safety challenges: Helps eliminate many of the safety challenges and restrictions associated with drill and blast. Fewer underground concerns: Eliminates seismic waves so operators can mine closer to underground pipelines, areas with high water tables or underground utilities. Continuous surface mining…
