深部采矿面临地压活动强烈、矿岩破碎、稳定性差等诸多难题。针对安庆铜矿22#采场矿体赋存较深,且破碎的特点,分析采用上向水平分层充填采矿法进行开采的技术解决方案,提出将采场划分为3部分并按先后顺序呈阶梯状推进的合理回采及充填措施。矿山实践结果表明,阶梯推进和采后及时充填能有效维护采场稳定,充分回收矿产资源,确保矿山安全高效生产。
Deep mining is facing many problems such as strong ground pressure, broken ore rock and poor stability. According to the characteristics of deep ore body of No.22 stope in Anqing Copper Mine and its fragmentation, the paper analyzes the technical solution of mining with upward stratified filling mining method, and puts forward that the stope is divided into three parts and the order is as follows Step-wise propulsion and filling measures. Mine practice results show that the step-by-step propulsion and post-harvest timely filling can effectively maintain the stability of the stope, fully recover the mineral resources and ensure the safe and efficient production of the mine.
