摘　　要：基于"采前加固"和"采后治理"的"两阶段"留巷原则,分析了留巷围岩控制的主控因素,制定了潘一东轨顺沿空留巷围岩支护对策,进行了沿空留巷工业性试验,试验结果表明,采用"两阶段"支护方案后,留巷表面位移量较小,围岩稳定,支护效果良好。Based on ＂two- stage＂ retaining roadway principles of ＂ strengthening before mining＂ and ＂governance after mining＂, the paper analyzed main controlling factors of surrounding rock control, developed surrounding rock support countermeasures of Panyidong rail along goaf, made industrial test. The results showed that surface displacement was small, surrounding rock was stability, support effects were fairly good after using supporting scheme of ＂two- stage principles＂.
