| 摘 要： | 三山岛金矿床属于典型的破碎带蚀变岩型金矿,随着开采深度的加深,涌水量不断增大。该文采用水文地质调查、地下水动态观测、水文地质试验、水样分析与测试等手段,查明了矿床水文地质条件,分析了充水因素,认为随着开采水平的加深,深部构造裂隙水逐渐成为深部矿坑充水的直接补给来源,且开采水平越深,深部构造裂隙水的贡献率越高。结合矿区实际涌水量,采用地下水流数值模型对不同开采水平进行了涌水量预测,预测-780 m开采水平矿坑涌水量为54 155 m3/d,-870m开采水平矿坑涌水量为66 611 m3/d,-960 m开采水平矿坑涌水量为82 387m3/d,该结果可作为矿山制定防水、治水方案的依据。

| Abstract: | Sanshandao gold deposit belongs to typical fracture zone altered rock type gold deposit. Accompanying with the deepening of mining depth, the water inflow is increasing. Hydrogeological survey, groundwater dynamic observation, hydrogeological test, water sample analysis and test are used to find out hydrogeological characteristics and water filling factors. It is indicated that with the deepening of the mining level, deep structural fissure water gradually becomes the direct supply source of deep pit filling water, and the deeper the mining level, the higher the contribution rate of deep tectonic fissure water. Based on the actual inflow in the mining area, the groundwater flow numerical model is used to predict the water inflow of different mining horizontal sections. It is turned out that water inflow is 54155 m3/d at the depth of 780m, 66611m3/d at the depth of 870m, and 82387 m3/d at the depth of 960m. It can be regarded as the basis for the prevention and control of water treatment. |
