摘要:According to the occurrence conditions of deeply inclined coal seam of 81206 working face in Yanya coal mine, methods including transmission rock theory calculation and numerical calculation based on the relationship between supports and surrounding rock are used to calculate and analyze. The proper working resistance of support is 5979.2kN and the supporting intensity is 0.8~0.95MPa. The regression equation associated with roof subsidence displacement, thickness of the coal seam, working face length and supporting intensity is accomplished, which provides theoretical basis for the support selection. © (2014) Trans Tech Publications, Switzerland.
