伯方矿掘进工作面巷道围岩压力研究及支护设计

Mining Roadway Working Face Roadway Surrounding Rock Pressure Research and Support Design

针对伯方矿的围岩大松动圈地质情况,对该矿3211回风巷道进行了支护设计,确定了3211回风巷采用了锚杆加锚索联合支护方案,并对巷道支护的效果进行现场实测。现场结果表明:采用联合支护后3211回风巷变形趋于稳定,联合支护方案可行。

Based on surrounding rock big loose circle geology condition of Bofang Mine, 3211 return air roadway support of the mine was designed, anchor bolt and anchor rope combined support plan was set up, the support effect was measured on the site. The result showed that the deformation of the return air roadway became stable, the plan was feasible.
