随着我国煤矿开采规模的扩大,浅部煤层日趋减少,开采深埋藏煤层将成为必然选择。但矿山在进入深部开采后,巷道围岩出现显著变形,破碎严重,对巷道围岩稳定性的控制变得极其困难。到目前为止,还没有摸索出一套有效支护深埋藏煤层开采巷
With the expansion of coal mining in our country, the shallow coal seams have been declining day by day, and deep-buried coal seams will become the inevitable choice. However, after the mine entered into deep mining, the surrounding rock of the roadway appeared obviously deformed and severely broken, which made it extremely difficult to control the stability of surrounding rock in the roadway. So far, no set of effective support for deep buried coal seam mining has not been explored
