Measurement of surrounding-rock deformation and support-resistance demand in roof-cut automatically formed roadways of inclined thick coal seams
The deformation control of roof-cut automatically formed roadways in inclined thick coal seams is strongly dependent on the reliable measurement of roof subsidence, rib convergence, stress redistribution and support-resistance demand. Taking the 1703 fully mechanized top-coal caving face of Hongling Coal Mine as an e...
