摘要
矿产资源为不可再生资源,如何最大限度地回采矿产资源,确保回采效率和安全,为国民经济建设服务,是每一个采矿工作者都要面对的问题。郝家河铜矿通过对浅孔房柱法的改进,采场之间不留壁柱,采用“V字形后退式”回采顺序,有效地增加了矿石的回采率、确保回采安全。
Mineral resources are non renewable resources.How to maximize the mining of mineral resources,ensure the mining efficiency and safety,and serve the national economic construction is a problem that every mining worker has to face.Through the improvement of shallow hole room pillar method in Haojiahe copper mine,there is no wall pillar between stopes,and the"V-shaped backward"mining sequence is adopted,which effectively increases the ore recovery rate and ensures the mining safety.
