围岩移动传感器在巷道围岩监测中的应用

Application of Surrounding Mobile Sensor in Roadway Surrounding Rock Monitoring

通过采集开元矿9402综采工作面回采期间进风顺槽围岩移动传感器矿压监测数据,对9402进风顺槽巷道顶板进行离层位移跟踪监测,实时掌握顶板位移动态变化情况。监测数据显示,进风顺槽顶板围岩没有发生显著的离层现象,锚杆、锚索联合支护技术及支护参数可以达到支护目的,顶板锚固效果较好,可以保持9402工作面顶板围岩的稳定,满足工作面安全生产的需要。

By collecting the mine pressure monitoring data of the mobile sensor along the surrounding rock of the 9402 fully mechanized mining face of Kaiyuan Colliery,the paper carries out tracking monitoring of the separation layer displacement of the roof of the 9402 air intake duct roadway,and grasps the dynamic change of the roof displacement in real time.The monitoring data shows that there is no obvious separation of the roof surrounding rock in the air intake duct roadway.The combined support technology and support parameters of bolts and cables can achieve the purpose of support.The roof anchoring effect is good,which can maintain the stability of the roof surrounding rock of the 9402 working face and meet the needs of safe production of the working face.
