基岩裂隙充水矿床因埋藏于非可溶岩类坚硬或半坚硬岩层中,充水裂隙埋藏条件、水动力性质等较不均匀;山东招远夏甸金矿作为典型的基岩裂隙充水矿床,经多年开采,矿床深部水文地质条件发生很大改变,矿床充水因素判定受工作条件限制存在一定困难。本文利用以地下水化学特征分析为主要内容的水文地球化学方法,结合水文地质条件和充水特征,判断其矿井深部裂隙涌水的形成背景和原因,得出矿床深部以脉状构造裂隙水为主要充水来源的结论,为基岩裂隙矿床充水来源等因素的判定提供了一定理论和实践依据。
The bedrock fissure-waterflooding bedrock is buried in the hard or semi-hard rock layers of nonsoluble rocks, and the waterflooding fractures are buried under the conditions of hydrodynamics. The Zhaoyiaxiadian gold deposit is a typical bedrock fissure waterflooding deposit After many years of exploitation, the hydrogeological conditions in the deep of the deposit have undergone great changes. It is difficult to determine the factors that affect the water-filling of the deposit subject to the working conditions. In this paper, we use the hydrogeochemical method, which takes the analysis of groundwater chemical characteristics as the main content, combined with the hydrogeological conditions and water filling characteristics to determine the formation background and reasons of the deep fissure water inflow in the mine. It is concluded that the fissure- The conclusion of water source provides some theoretical and practical evidences for determining the source of water fills in bedrock fractured ore deposits.
