摘要
随着矿井向深部区转移,矿山压力增大,其巷道支护方式也将发生较大变化。裴沟矿区通过巷道支护方式的演变,巷道支护逐步贴近利用巷道支护与围岩共同承载的支护原理,大大提高了支护强度,降低了巷道失修率和返修率。
As the mine transfers to deep zone, the mine pressure increases, the support way of roadways will change largely. Through the evdution of roadway support way in Peigou mine area, the roadway support step by step closes the support principle of common bearer of roadway support and rock. The support strength is largely raised. The rate of disrepair and back repair is reduced.
