大兴安岭北部砂宝斯金矿水文地质特征及供水方向评价

砂宝斯金矿位于额尔古纳隆起的北东端，上黑龙江断陷盆地的边缘，共固定5条工业矿体，平均金品位1．19×10^-6，主要含水层为中侏罗统二十二站组砂岩、下寒武统额尔古纳组大理岩。通过分析矿区供水条件，指出矿区地下水贫乏、水质差，不能满足未来矿区生产、生活需要，需进行以地表水为主的供水，认为小东沟河可作为未来矿区首选供水源，开采时应注意钻孔封孔质量。

Evaluation on Hydrogeology Features and Watersupply Direction of Shabaosi Gold Mine in North Daxing'anling

The Shabaosi gold ore is located in northeast of Ergun up lift and the edge of upper Heilongjiang fault basin. There are five industrial ore bodies, the average gold grade is 1.19×10-6, the main water-bearing stratum is middle jurassic 22 station group sandstone, lower cambrian Ergun marble. Through analysis of the water supply condition analysis, we pointed out that the ground water volume of the mining area is deficient, the water quality is poor, that will not be able to satisfy the needs of future mining area production life,we will have to carry on water supply by the surface water primarily, Xiaodonggou river could be the first choice for future miningwater, and we should pay attention to seal the hole of the drill hole quality while mining.
