摘　　要：堆浸过程中,存在着滑坡和泥石流两种地质灾害。分析了灾害产生的原因及其可能造成的危害,探讨了堆浸场地质灾害发生机制的宏观表象与微观反应之间的内在联系;重点分析了微观机理中溶浸液在堆场中的赋存状态以及矿石颗粒内部的反应过程。以铜浸出为例,分析了铜浸出过程中的化学反应机理。Geological hazards such as landslide and debris flow possibly occur in heap leaching. The reasons and possible harms of the geological hazards are analyzed, The inherence relations between macroscopical phenomenon and microcosmic reactions on the mechanism of the geological hazards in heap leaching are discussed. The existent status of leaching solution in ore dump and the reaction process in ore particles are mostly researched, Take copper leaching as example, the mechanism of mechanical reaction in leaching is analyzed.
