摘要： 为了研究矽卡岩型矿山井下淤泥回收的可行性，以某矽卡岩型铁矿为研究背景，针对该类型地下矿山产生的淤泥较多、清理时间长、处理困难、费用高的问题，进行了一系列的淤泥回收研究与实践。通过对各生产中段排水沟、沉淀池、水仓中的淤泥取样，进行品位化验，得出淤泥铁含量平均品位为22.41%，大于边界品位，具有回收价值。通过通过分析井下淤泥产生的原因、制定淤泥回收方案、开展淤泥回收实践，不仅提取淤泥中的铁矿资源，而且提高了井下排水泵的使用寿命，实现了金属回收率的提高和矿石损失率的降低，进一步证明了矽卡岩型矿山淤泥具有很好的利用价值，为类似矿山在井下淤泥回收方面提供了一个可行性的借鉴实例。

Abstract: In order to study the feasibility of underground sludge recovery in skarn mines，taking a skarn iron mine as the research background，a series of sludge recovery research and practice are carried out in view of the problems of more sludge，long cleaning time，difficult treatment and high cost in this type of underground mines.Through the sampling of sludge in the drainage ditch，sedimentation tank and sump of each production section，the grade test is carried out. It is concluded that the average grade of sludge iron content is 22.41 % ，which is greater than the boundary grade and had recovery value. By analyzing the causes of underground sludge，formulating sludge recovery plan and carrying out sludge recovery practice， not only the iron ore resources in the sludge are extracted，but also the service life of the underground drain‐ age pump is improved，and the metal recovery rate is improved and the ore loss rate is reduced. It is further proved that the sludge of the skarn type mine has good utilization value，and provides a feasible reference ex‐ ample for similar mines in underground sludge recovery.
