摘　　要：本文从原地破碎浸出法采矿要求出发 ,对 3 2 2铀矿田碎裂蚀变花岗岩型铀矿床 (点 )的地质构造、岩 /矿石物质成分、矿石结构、铀的赋存形式、岩 /矿石物理力学参数、矿体形态、产状、规模及矿床水文地质条件进行了研究 ;通过原地爆破筑堆试验及一系列铀矿的柱浸工艺试验 ,获得了大量原地破碎浸出参数 ;运用原地破碎浸出法适用性评价模型对其进行了评价 ,认为该矿田碎裂蚀变花岗岩型铀矿床适宜采用原地破碎浸出法开采。According to the technological demands of the in place crushing leaching method, this paper discusses the natural geological conditions of uranium ore field No.322, such as: geological structure, components of rocks and ores, ore texture, existing state of uranium, physical and mechanical parameters of rocks and ores, the shape, attitude and size of orebodies, as well as hydrogeological conditions of deposits. Meanwhile, a great number of technological parameters have been obtained by both the in place blasting stacking test and a series of column uranium extracting tests. At last, the conclusion that the in place crusing leaching method is suitable for the cataclastic altered granite type uranium deposits in the ore field is proposed by a evaluation model for the in place crushing leaching method.
