针对阿舍勒铜矿650 m中段破碎围岩矿体,采用分段崩矿阶段空场嗣后充填采矿法采场发生垮塌的状况,提出了预控顶分段空场嗣后充填法开采的技术方案。7个采场的回采实践表明:该采矿方法适合阿舍勒铜矿上盘围岩破碎矿体的开采技术条件,并具有采场稳定性好、作业安全、贫化损失率低、生产能力大、综合经济效益高等突出优点,采场实际损失率为4%~5.7%、贫化率为3.3%~10.9%。
Aiming at the fractured surrounding rock mass of 650 m middle Ashele copper mine, the collapse of stope at the subsidence stage after subsided during the period of subsidence at the subsidence stage was proposed. . The practice of 7 stopes shows that the mining method is suitable for the mining technology conditions of the surrounding rock mass crushed ore body in the Ashele copper mine and has the advantages of good stope stability, safe operation, low depletion loss rate and large production capacity , With outstanding advantages of high comprehensive economic efficiency, the actual loss rate of stope is 4% -5.7% and the depletion rate is 3.3% -10.9%.
