寿王坟铜矿自1957年投产以来已开采40年.井下形成了大小不等的百余个采空区,其中南6号矿体采空区为最大,体积约为140万m3,对矿山井下开采安全构成严重的威胁.对多种控制方案进行了研究并进行了空区处理,同时在空区实施岩体声发射监测.对声发射监测方法及其结果作了论述.
Shouwangfen Copper Mine has been mined for 40 years since it was put into operation in 1957. There are over a hundred goafs of different sizes formed in the mine, of which the No.6 ore body in the south is the largest with a volume of about 1.4 million m3, which poses a serious threat to mine safety. A variety of control schemes were studied and empty areas were treated, while acoustic emission monitoring of rock mass was carried out in the open area. The acoustic emission monitoring methods and their results are discussed.
