摘　　要：北衙金矿区是以溶蚀裂隙岩溶含水层为主的矿床,大部份矿体位于当地侵蚀基准面1694米(W123泉)以下,水文地质勘探的程度为以溶蚀裂隙含水层充水为主的复杂类型,标高1734米以上为简单类型。以抽水试验取得成果,介绍矿区矿坑涌水量预测采用的主要预测方法。通过矿山后续排水疏干的实际情况,对预测的方法和矿坑涌水量进行论证。The main rock bed in Beiya Au orefield is the solution fissure karst aquifer.And the most ore bodies are below the local erosion basis 1694m(spring w123),which belongs to the complex type of water filling,ie,mainly water filling of solusion fissure aquifer,whereas the simple type is above the altitude 1734m.According to the result derived from the Abstraction testing,the main prognosis method of tunnel well yield of orefield is introduced in this paper.And the verification of prognosis method and tunnel well yield is carried out with the reality of the later drainage and dry up in the mining.
