跨采影响巷道高强锚网支护的应用研究

Applied research on the roadway bolt mesh support effected by crossing mining

跨采工作面具有不留保护煤柱、少掘开切眼、不用设备搬家等优点,但是,跨采巷道受地压和动压双重叠加影响,巷道支护十分困难。运河煤矿23611工作面跨采影响下的南皮下山巷道采用高强锚网支护,取得了良好的支护效果,对类似跨采巷道的支护设计具有一定的借鉴价值。

Crossing mining working face has no protective coal pillar, few open-cut, and little equipment moving and other advantages, however, due to the dynamic pressure effect, roadway supporting is very dififcult. The southern belt descending under the inlfuence of 23611 working face used the high strength anchor net support, has achieved good supporting effect, has a certain reference value to the similar roadway support design.
