摘　　要：针对阿舍勒铜矿650m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％。To solve the problem that the fractured surround- ing rock at 650 meters in Ashele Copper mine collapsed with sublevel blasting and bench open-stope mining with subse- quent filling method, a new precontrolling of roof and sub- level open-stope mining with subsequent filling method was proposed. Practical results in 7 stopes showed that this min- ing method was suitable for mining condition here, with many advantages such as excellent stability in stope, operat- ing safety, low loss and dilution rates, high capacity and good economic benefits, ect. The actual loss rate was 4%～5.7%, and the dilution rate was 3.3%～10.9%.
