摘　　要：针对复杂充填体下大型贫矿体的开采,用传统的采矿方法存在着矿柱不能安全高效回收、资源损失大、采场顶板控制困难、采空区处理技术难度大、成本高、易诱发大规模地压、矿山安全没有保障等一系列问题,对此中南大学采用了高分段中深孔崩矿顶板诱导崩落连续采矿法。通过在铜坑矿92号矿体的工业试验,该技术较传统采用的采矿方法有许多的优点,并取得了较好的技术经济指标,对类似矿体的开采有一定的指导作用。To mine large-scale poor orebody under complicated fillingbody, the traditional mining methods have a series of problems such as ： lower safety and efficiency at mining the jamb, large sources loss, difficult to control stope＇s roof, hard difficulties with abandoned stope＇s disposal, high cost, easy to cause large-scale ground press, no safety guarantee to the mine, and ect, To solve these problems, Central-South University adopts mining by middling depth explosive bores with high subsections and derivation- al roof caving-successive mining method. Through the industrial trial on No. 92 orebody of Tongkeng Mine, the technology is proved to have many strongpoints than the traditional mining methods and it can get better technic and economic targets. It has instructional value to similar orebodies＇ mining.
