大断面破碎围岩巷道交叉点支护技术研究

Intersection Support Technology in Large-Section Roadway with Broken Surrounding Rock

结合王村煤矿地质条件,对大断面巷道支护技术进行了论述,提出交叉点大断面破碎围岩巷道的支护方式,通过采用锚杆+锚索+钢筋网+喷浆支护技术,取得了良好的支护效果,确保了巷道的安全。

On the basis of the support status at the intersections in large -section roadway and the practice sum‐marization in Wangcun Colliery ,the author presents the support method with anchor bolt -cable -mesh and shotcrete at intersection in large -section roadway with broken surrounding rock in terms of design and con‐struction ,which has achieved a good supporting effect ,and ensured the safety and reliability of the roadway .
