A combined opencast-to-underground mining method is widely used for final extraction of border zone coal reserves and extracting areas with limited and non-technological reserves. The idea of the method is that coal is extracted by opencast method and continued by underground mining using highwall mining complex, mobile mining mechanical equipment, augers, mechanized complexes and water jetting facilities.
