摘　　要：介绍了我国铜矿排土场资源状况。分析了德兴铜矿堆浸场生产现状 ,指出了铜矿排土场堆浸中存在的问题。阐述了管注浸出法的原理及主要工艺技术 ,认为必须加强浸堆中的渗流场。The resource of large dump pits of copper mines in China is described. The present state of heap leaching of Dexing Copper Ore is analysed, and some existing problems of heap leaching of copper mine's dump pits is pointed out. The principle and key techniques of the tube pouring leaching method are discussed. It is concluded that more attention should be paid to the study of the distribution and changing characters of seepage field, temperature and stress field in heap.
