Geomechanical justification of the application of concave-flat shape of mine excavation stope face to control sudden rock spelling
In the conditions of Verkhnekamsk and Starobinsk potash deposits the phenomena of gas dynamics that represent sudden stope face rock spelling occur during primary and cleaning mining operations. Sudden spelling of stope face rocks starts from the flat face with rate of less than several tones. Nev...
