Using upward drift-fill stoping in the west of -80m sublevel of south ore zone in Wushan Copper Mine, roof fall and caving happened oftenly because of bad mine rock stability, and the production couldn′t continue.
武山铜矿南矿带 - 80m中段西部矿体 ,采用上向进路式水砂充填法开采 ,由于矿岩稳固性较差 ,经常冒落垮塌 ,无法继续生产 ,对此 ,改用下向分层水砂充填法进行开采 ,取得显著效果。
Instead of the foremethod, the undercut-and-fill stoping was used, and remarkable success was achieved.
