摘　　要：梨树煤矿建矿以来一直受软岩困扰。该矿通过对软岩巷道岩性的分析,以采面上、下巷为主,应用悬吊理论与组合梁理论,设计锚、网、索、钢带的联合支护方式,有效地控制变形、片帮,为矿井安全有效地管理软岩巷道提供了科学依据。Lishu Coal Mine has been plagued by soft rocks. By analysis on the lithology of soft rock ttmnels, taking the upper and down tunnels as dominant factors, the theory of suspension and compound beam was applied,the combined support with bolt, net, cable and steel belt was designed. The deformation and wall caving were effectively controlled. The scientific basis was provided for controlling soft rock tunnels safely and effectively in coal mines.
