According to the specific engineering geology conditions of-1000m level northern trackage contacting roadway in Qishan Coal Mine,the reasons for deformation and failure of support are analyzed.The feasible support schemes for the deep roadway engineering are put forward.And then some feasible schemes are optimized by numerical simulation.The support scheme of bolt-shotcrete-mesh-anchor and spouting coupling support are proposed.The field construction observation and measurements of the roadway show the coup...
