Theoretical analysis of stability of unconventional gateroad pillar employing longwall mining with split-level gateroads

By adjusting longwall top coal caving panel,gateroads on either end of the LMSG (longwall mining with split-level gateroads) panel are arranged at different levels within a coal seam,gateroads of the adjacent panels are offset spatially,unconventional gateroad pillar was developed.A structural model...
