| 摘 要： | 为解决大规模地下贫矿体连续开采存在的顶板安全管理问题，通过相似模拟材料试验，对复杂充填体下大型贫矿体的地下连续开采进行了研究，包括矿体安全顶板的自然崩落性和顶板人工诱导崩落的时序系统研究。结果表明，安全顶板自然崩落性差，采用顶板人工诱导崩落技术，实施合理的采、放顺序。可以保证矿体的安全回采，为地下矿体连续回采和顶板安全管理提供了科学依据。

| Abstract: | in order to solve roof safety problem of continuous mining in large-scale underground poor orebody,by similar simulated experiment,continuous mining of the large lean ore under complex filling is studied,involving the study of natural dilapidation and the scheduling system of artificial inducement dilapidation of the roof.The results show that natural dilapidation of the safe roof is not good,but using the artificial inducement dilapidation technology and carrying out the reasonable order of extracting and caving can guarantee the mining safety and provide the necessary scientific proof to continuous mining of the ore body underground and safety management of roof. |

| Keywords: | roof dilapidation resemble simulate scheduling system continuous mining underground |
