摘 要:根据沿空掘巷的技术特点,采用理论推导分析和数值模拟方法得出窄煤柱沿空掘巷合理煤柱宽度并优化了支护参数,对锚网梁索联合支护效果进行了监测与分析。矿压监测结果表明,支护设计合理,巷道围岩变形在工程允许范围内,满足了安全生产需要,为采动影响下沿空掘巷提供了科学的方案,获得了较好的实践经验。According to the technical characteristics of driving roadway along gob, the reasonable pillar width was determined by the means of theoretical analysis, support parameters were optimized, and the effect of combined supporting with bolt mesh and cable was monitored and analyzed in driving roadway along gob withe narrow coal pillars. The results of ground pressure monitored show that the support design is reasonable and roadway deformation within the project to allow, the mining safety needs was met. A scientific program was provided for driving roadway along gob under the mining influence, and a better experience was obtained.
