摘　　要：在七四五矿对常规方法开采无经济价值的一独立矿体进行了万吨级就地破碎浸出试验。试验中，采用了深孔爆破落矿筑堆，为了控制筑堆形状和矿石粒度，对深孔落矿方式和参数作了分析研究；根据试验矿体的具体开采技术条件，选择了适宜的采场底部结构，实现了多点集液，达到了防止浸出液漏失的目的。An experimental study on the in situ explosive fragmentation and leaching of a separate orebody,which was uneconomical value to the conventional mining,was made on a 10000t scale in NO.745 Mine.In the test,the heaps were constructed by the longhole blasting.In order to control the heap shape and the ore grain size,the method and parameters of longhole caving were analyzed.According to the practical conditions of mining technology for the test orebody,the suitable stope bottom structure was selected to hit the targets of both multi point solution containment and preventing the leaching solution leakage.
