Stability of roof structure and its control in steeply inclined coal seams
To improve the effectiveness of control of surrounding rock and the stability of supports on longwall top-coal caving faces in steeply inclined coal seams, the stability of the roof structure and hydraulic supports was studied with physical simulation and theoretical analysis. The results show that...
