摘 要:寿王坟铜矿自1957年投产以来,已有40年的历史,采区内已形成大小不等的采空区100余个,其中南六号采空区体积最大,达140万m3,该空区的下部还有矿石储量约550万t。由于该矿资源已十分有限,这部分资源的回收十分重要,而回采顺序及采矿方法选择的正确与否直接关系到资源的回收率和作业的安全。本文较详细地阐述了回采顺序与采矿方法的选择和参数。Shouwangfen copper mine has been in,mining for 40 years since it began production in 1957. During the 40 years' mining activity, there are over 100 mined -out areas in the mine. The South No. 6 is the biggest among them(1.4 million m^3). There is an ore reserve of about 5.5 million tons beneath it. The mining of the reserve is very important for the mine since mineral resources in the mine are very limited. Since the complicated environment around the orebody, it becomes very important to make the correct choice of mining method and the mining sequence for the high recovery and the mining safety. The study around this is described in this paper.
