摘要

相山铀矿田西部是相山矿田重要成矿区域,水文地质条件属简单-中等类型。通过矿山开采实践,结合探采对比研究以及多个钻孔抽水试验资料分析,表明相山西部大部分矿床主要矿体位于当地侵蚀基准面以下,河水与地下水水力联系较差,对矿床充水不构成威胁;地质构造较复杂,但无强导水构造,地下水补给条件好,水压高,而影响矿床充水的主要含水带——构造(次级构造)裂隙含水带富水性弱,估算矿坑涌水量小,但矿床开采过程中应加强监测,及时判断可能出现的涌水量变化情况,保证生产安全。
        The west of Xiangshan uranium ore field is an important metallogenic area of Xiangshan ore field, and the hydrogeological conditions belong to simple to medium type. Based on mining practice,combined with the comparative study of exploration and mining and the test data of pumping water from several boreholes, it was shown that most of the ore bodies in the west of Xiangshan are located below the local erosion datum, and the hydraulic connection between river water and groundwater is poor.Water filling does not pose a threat to the deposit. The geological structure is complex, but there is no strong water conductivity structure, the groundwater recharge condition is good. The water pressure is high, but the main water-bearing zone-the structure( secondary structure) fissure water-bearing zone, which affects the water filling of the deposit is week in aquosity, the estimated water inflow of the mine pit is small. However, during the course of mining, the monitoring should be strengthened to judge the change of water discharge in time to ensure the safety of production.
