Applications Applied Mining Tech

Highwall mining is used in open-cut coal mining operations with a continuous mining machine and a modular conveyor train being remotely driven into the exposed coal seam at the base of an open-cut highwall. The extraction process creates multiple tunnels that can extend over 500m, with supporting coal pillars left in between.
