凤凰山铜矿-360m中段采矿方法的改进

Improvement of Mining Methods for -360 m Level Middle Section of Fenghuangshan Copper Mine

凤凰山铜矿 - 3 6 0m中段深部开采设计采用浅孔留矿法、VCR法和水平分层充填法 ,实际开采中进行了两次改进 ,即缩小充填法采场的尺寸 ,采用尾矿充填扫面技术 ,取得了多回收矿产资源 ,提高回采安全性的良好效果。

The deep mining for -360 m level middle section was designed to use short hole shrinkage stoping, VCR method and horizontal sublevel filling method. In the practicle production, two improvements were made, namely reducing the stope area that was to be mined by filling method and adopting the technology of tailings cemented filling and paving of surface, which achieved good effects of recovering more mineral resource and raising the safety of stoping.
