桃山煤矿14138工作面高抽巷锚梁网支护技术研究

Research on Combined Support Technology with Anchor Beam Net in High Drainage Roadway at No.14138 Face in Taoshan Coal Mine

针对桃山煤矿14138工作面高抽巷外段与里段顶板岩性相变较大、巷道围岩控制难度大的工程实际,依据计算机数值模拟确定支护技术参数。现场工程实践表明,高抽巷锚梁网支护具有良好的适用性,可在同等条件下推广应用。

In the high level suction roadway of Taoshan Coal Mine 14138 face, the roof lithology greatly changes at the outer segment and segment. It is very difficult to control the surrounding rocks of roadways in engineering practices. The technical parameters of supporting are determined based on computer numerical simulation. The engineering practice shows that the combined support with anchor beam net has good applicability in the high level drainage roadway, it can be applied in the same conditions.
