The highwall mining system is a strong, self-propelled machine that operates on contour benches as narrow as 18 m (59 ft). It trams easily from entry to entry and discharges coal in tight spaces. An optional right-angle conveyor system discharges coal on the right or left side on narrow benches.

Highwall mining is a mechanized and productive method compared to conventional underground mining methods. It leads to added recovery of coal which is otherwise lost in the pit below the highwall.

Highwall mining is a proven primary method for mining coal from exposed seams. In this method of mining, an unmanned cutter module is driven underground and operated in front of the highwall. The highwall mining machine stands on the pit loor or on a bench, directly in front of the exposed seam and makes long parallel rectangular drives into
