摘要
针对陕西彬长文家坡矿业有限公司4106工作面运输顺槽巷道变形严重问题,设计采用锚杆+金属网/塑钢网+W钢带+锚索联合支护方案。在顺槽内布置2个测站,监测结果表明:巷道围岩顶底板和两帮变形量得到有效控制,支护效果良好。
Aiming at the serious deformation problem of transportation roadway in the 4106 working face of Shanxi Binchang Wenjiapo Mining,the combined support scheme of bolt+metal mesh/plastic steel mesh+W steel belt+anchor cable is adopted.The monitoring results show that the deformation of roof,floor and two sides of roadway surrounding rock is effectively controlled,and the supporting effect is good.
