摘要
矿床水文地质条件是决定砂岩型铀矿床是否适宜地浸开采的重要条件之一。宝龙山铀矿床是近几年发现的规模较大的地浸砂岩型铀矿床,2012年度在矿区施工了一组水文地质孔,通过岩心编录、综合测井及抽水试验等方法,确定了宝龙山铀矿床含矿含水层的埋深、厚度、岩性、岩石成分、孔隙度、渗透系数、单位涌水量及隔水顶底板厚度、稳定性等水文地质特征参数,依据规范要求对宝龙山铀矿床进行地浸水文地质条件初步分析评价,认为该矿床水文地质条件良好,满足地浸开采要求。
The hydrogeology condition of sandstone-type uranium deposit is one of the most important conditions which decide the feasibility of in-situ leachmining.Baolongshan uranium deposit is the larger sandstone-type uranium deposit was found in recent years.a set of hydrogeological hole were implemented in deposit in 2012,through these methods that core geological record,comprehensive logging and pumping test and so on,Making sure the hydrogeological parameters of aquifer's burial depth,thickness,lithology,rock constituents,porosity,coefficient of permeability,specific capacity,the thickness of Waterproof roof and floor and stability of Ore-bearing aquifer in Baolongshan uranium deposit.Analyzing and evaluating hydrogeologic condition for in-situ leach mining according to the uranium deposit in general.It has been concluded,that hydrogeologic condition in the study area is favorable,meeting the requirements for in-situ leachmining of the deposit.
