山东省郗山稀土矿矿区西部水文地质条件分析

Analysis on Hydrogeological Conditions of Western Xishan Rare Earth Mining Areas in Shandong Province

摘要:

通过地球物理勘探、水文地质调查、钻孔和抽水试验，结合区域水文、气象和地质等资料，对矿区西部的水文地质条件有了初步认识。区内将含水岩层划分为松散岩类孔隙含水岩层和岩浆岩类裂隙含水岩层；选用“大井法”与“比拟法”相对比，以“大井法”为主对矿坑涌水量进行了预测；通过水质分析结果，认为自然条件下微山湖地表水体对矿坑充水无补给作用。

Abstract:

Through regional hydrological, meteorological and geological data, geophysical exploration, hydrogeological surveys, drilling and pumping tests, hydrogeological conditions of the west of the mining area have been introduced preliminarily. Aquifer rock formations in this area can be divided into porous aquifer of unconsolidated rock strata and magmatic rocks fractured rocks rock formations. Comparing "big weel method " with "analogy method" , and selecting "big well method " as the main method, pit inflow has been forecasted. Through water quality analysis, it is regarded that under natural conditions, Weishanhu surface water has nonrecharging to waterfilled pit.
