摘要 大同煤矿集团晋华宫矿8714工作面回风巷受采掘作业以及矿山开采深度逐步增加和大面积连续开采的影响,巷道围岩表现出明显的蠕变特性,巷道围岩已发生不同程度的破坏,巷道支护问题非常突出。本文针对8714工作面回风巷的地质条件,设计了相应的支护技术方案,有效地控制了巷道围岩的变形,为同类受采动影响下巷道支护技术提供了参考。 As the return air roadway of 8714 working face, Jinhuagong Coal Mine, Datong Coal Mine Group, has been influenced by mining operations and incease in mining depth and the large area of continuous mining, the surrounding rock of roadway showed obvious creep property, there have been varying degrees of damage, and the roadway support problem is very outstanding. According to the geological conditions of 8714 face return air lane, this paper designs the corresponding supporting technology, effectively controls the deformation of surrounding rock of roadway, and provides good references for roadway supporting technology under the influence of mining.
