同地北杏庄煤矿运输巷支护方式研究

Study on the supporting method of transportation roadway in Bei Xing Zhuang coal mine

同地北杏庄煤矿1230运输巷主要服务于技术改造后的全煤矿运输工作,根据之前周围类似煤矿的支护经验进行设计施工,巷道支护原则上采用锚杆与锚索联合支护,在局部顶板破碎处采用补架工字钢梁的方式进行辅助支护。

1230 roadway in Bei Xing Zhuang coal mine mainly is used for the mine all transportation work after the technological transformation, the supporting method was selected and constructed according to previous similar experience around coal mine, the roadway support in principle used the bolt and anchor combined support, in local roof breaking points took the reinforcing frame steel I-beam way as the auxiliary support.
