摘　　要：针对以《稀土金属地质勘查规范》(DZ/T 0204—2002)为代表的地质勘查规范对矿床开采技术条件的勘查要求基本不适用于原地浸矿工艺开采的问题,系统分析了原地浸矿工艺的开采特点,针对拟采用原地浸矿工艺生产的矿山,对其矿床开采技术条件的合理勘查程度及勘查重点进行了探讨。研究表明:(1)勘查阶段宜划分预—普查、详查2个阶段,开采技术条件勘查类型宜确定为以环境地质条件为主的中等类型矿床(Ⅱ-3)或复杂类型矿床(Ⅲ-3);(2)矿床渗透性、浸矿山体稳定性、地下收液工程稳定性以及浸取产生的环境污染问题是开采技术条件勘查的重点,并进一步分析了具体的勘查内容及要求,对于相关地质勘查规范制(修)订以及合理部署矿床开采技术条件勘查工作有一定的参考价值。To solve the problem that the exploration requirements on mining conditions of the current solid mineral geological exploration norm such as the ＂ rare earth metal geological exploration norm＂（ DZ/T 0204—2002） are not suitable for in-situ leaching mining,the mining characteristics of in-situ leaching is analyzed systematically,and the reasonable exploration extent and key contents of the mining technical conditions of the deposits that the in-situ leaching technique will be used. The study results show that：（1）the deposit prospecting stage can be divided befittingly into pre-general survey stage and detailed investigation stage,the exploration types can be determined befittingly as medium（ Ⅲ-3） or complex types of deposit which is focused on environmental geological conditions;（2）the prospecting key contents of mining technical conditions are mainly for permeability of deposit,stability of in-situ leaching hill,stability of underground recovery engineering and environmental pollution problems caused by leaching,besides that,the concrete exploration contents and requirements are analyzed,so as to provide some reliable reference for making ore revising the geological exploration norms and the reasonable arrangement of exploration work of mining technical conditions of the deposit that the in-situ leaching technique is adopted.
