The article presents a case study of a KGRP (highwall miner) operation at the Sokolovskoe coalfield. In particular, opportunities of this technology for effective and economically efficient development of coal seams are substantiated. It is also proved that with the average coal seam thickness of 7.33 m, the average output of a KGRP exceeded 68 TPH, while its peak output reached 200 TPH.
