摘　　要：针对多次跨采软岩巷道支护技术难题,从地质和开采2个因素,分析了跨采巷道围岩变形的主要原因及动压影响条件下的变形规律,提出了以加固岩体、封闭围岩和高阻让压支护三者相结合的软岩巷道支护设计思路,现场围岩电磁波波速和巷道收敛变形监测表明:新设计方案实现了巷道再次跨采时围岩变形量控制在了可接受范围内,确保了矿井的安全高效生产。According to the support technology problem for soft roadway with multiple cross-mining, based on the geological and mining two factors, the main reasons of surrounding rock deformation and the deformation law under the condition of dynamic pressure are analyzed, one support design idea with reinforcing rock mass, closing surrounding rock and high resistance yield support is put forward, the electromagnetic wave velocity and the surrounding rock of roadway convergence deformation monitoring show that the new design scheme can control surrounding rock deformation in an acceptable range when roadway cross mining again, the safety and efficiency of the mine production were ensured
