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