DOU Xiao-feng
Abstract：According to specimens of similar sections for the sampled numerical simulation, and the driving gob of supporting the program, the reasonable control of roadway surrounding rock and the anchor beam net support techni-cal parameters, single hydraulic prop with the cross-hinged roof beams were selected. Through the on-site observa-tion of mine pressure, it is concluded that the goal of reducing roof accidents, lower maintenance costs and mainte-nance time have been achieved for the safe and efficient purpose.
