摘要
基于朔州煤电有限公司8128回风顺槽掘进期间受集中应力影响,围岩出现严重破碎现象并伴随着局部冒漏,制约着巷道施工安全的问题,通过技术研究,分析了原支护设计主要存在的问题,对原支护进行优化,提出了“注浆加固+多筋梯子梁”联合支护措施。通过实际应用效果来看,支护优化后提高了破碎顶板控制效果,保证了巷道安全快速掘进,取得了显著应用成效。
Based on the fact that during the excavation of 8128 windrow in Xiaoyu coal mine,the surrounding rock was severely fractured and accompanied by local leakage,which restricted the construction safety of the roadway.Through the practical application effect,the support optimization has improved the effect of crushing roof control and ensured the safe and rapid tunneling of the roadway,which has achieved significant application effect.
