掘进巷道过断层破碎带支护实践研究

Research on the Practice of Supporting Tunnels through Fault and Fracture Zones

随着我国煤炭产量的不断增长和资源开采深度的增加,巷道掘进已成为制约矿井生产能力提高、成本增加和安全生产的主要因素之一。近年来,在掘进过程中遇到断层破碎带的情况越来越多,严重制约着巷道掘进速度,因此做好掘进巷道过断层破碎带的支护工作非常关键。基于此,本文结合某煤矿巷道开采工作展开分析,对本次巷道过断层破碎带的支护工作要点进行探索,保证工作面开采工作的安全进行,同时为后续类似工作的顺利开展提供参考。

With the continuous growth of coal production and the increase of resource mining depth in China,tunnel excavation has become one of the main factors restricting the improvement of mine production capacity,cost increase,and safety production.In recent years,there have been more and more cases of encountering fault fracture zones during excavation,which seriously restricts the speed of tunnel excavation.Therefore,it is crucial to do a good job in supporting the excavation of tunnels through fault fracture zones.Based on this,this article combines the mining work of a coal mine roadway to explore the key points of support work for the roadway passing through the fault fracture zone,ensuring the safety of the mining work on the working face and providing reference for the smooth development of similar work in the future.
