The hydrogeology of deposit is one of the most important conditions which decide the feasibility of in-situ leach mining.
矿床水文地质条件是决定一个矿床是否适宜地浸开采的最重要条件之一。

Based on the study of regional hydrogeology, the hydrogeological test was carried out at a uranium depositin DongBei, then the hydrogeological conditions for in-situ leach mining are evaluated.
During the test and production of in-situ leaching of sandstone deposit, it is very difficult and complicated to exploit boreholes when confined water head of ore-bearing acquifer is quite low.
