Based on Shanxi Jincheng Wangpo coal mine 3205 shipped shun detour affected by multiple stress and appearance serious problems such as large area of subsidence, roof, abutment pressure on the roadway, lateral abutment pressure and mining effect were analyzed, and the composite cement slurry and chemical pulp of high pressure grouting and cooperate with the strong anchor cable comprehensive reinforcement scheme was proposed. Site engineering practice showed that after adopting the reinforcement measures, shipped 3205 shun detour two maximum nearer to 45 mm, roof subsidence was 38 mm, the largest amount of drum at the bottom of the base plate was no more than 40 mm, and not for repair again, roadway can remain stable for a long time.
