The employment of dip retreat and wedge pipe bolt for roof support showed that the permissible exposed area of mine goaf increased from 50m2 to 258-500m2, thus greatly reduced the ore loss and dilution.
本文以理论研究为基础,密切结合生产实际,采用沿倾斜后退式回采顺序和楔管式锚杆护顶技术,使采空区允许暴露面积只有50m~2左右,扩大到258～500m~2,大幅度地降低了矿石损失与贫化,获得显著的经济效益。
