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 floor or on a bench, directly in front of the exposed seam and makes long.판매 된 highwall 광산 시스템,Ground Control Design For Highwall Mining - CDCU.S. coal production. Highwall stability is the major ground control related safety concern. Ground control plans for highwall mining should specify hole width, web pillar width, barrier pillar width and number of holes between barriers. This paper offers simple design charts for these parameters aimed at providing “ball park”.

HW300 Highwall Mining System | Finning

The HW300 produces high volumes of coal at very low costs. More importantly, it is safer than traditional underground mining, as it sends no one underground, and it works economically with a small crew and very little support equipment. It's versatile in its mobility and application, and it produces large quantities of coal at.
