矿压监测技术在巷道支护设计中的应用

Application of Mine Pressure Monitoring Technology in Design of Roadway Support

以三交河煤矿11-1041巷掘进期间围岩支护为研究对象,采用矿压监测技术对巷道支护效果进行监测。通过矿压监测可知,将工作面顶板“全锚索”支护优化为“锚杆+锚索”联合支护形式,降低了延米费用,提高了循环进尺,改善了围岩浅部破碎状态。

Taking the surrounding rock support during the excavation of 11-1041 roadway in Sanjiaohe coal mine as the research object,the mining pressure monitoring technology is used to monitor the effect of roadway support.It can be seen from the mine pressure monitoring that the full anchor cable support on the roof of the working face is optimized into the anchor+anchor cable combined support form,which reduces the per unit cost of the driving,improves the advance per round,and changes the crushing state of the shallow part of the surrounding rock.
