| 摘 要： | 运用水文地质分析、岩相古地理分析等方法研究了神东矿区不同类型水文地质结构特征、分布规律、水文循环特征和岩相古地理成因,基于突水案例分析了神东矿区各类水害水文地质特征.研究表明:神东矿区包含两类典型水文地质结构,一类为下侏罗统煤层顶板薄基岩上覆中至强富水第四系厚层松散孔隙水系统,矿井水害以浅埋深、薄基岩条件下的厚松散砂层突水和溃砂为典型;另一类为下侏罗统煤层顶板厚基岩上覆中至强富水下白垩统裂隙孔隙裂隙水系统,矿井水害类型以厚基岩条件下白垩系突水为典型.矿区西部较完整保存的直罗组为实现神东矿区白垩系保水采煤提供了天然屏障.本研究为神东和鄂尔多斯盆地其它矿区矿井水害防治及保水采煤奠定了可靠研究基础.

| Abstract: | Using the methodologies of hydrogeology and lithofacies paleogeography we categorize the hydrogeologic types of Shendong mining area,and develop the conceptual models of mining water hazards of each type.The study shows that,in Shendong mining area,there exist two types of hydrogeologic conditions:one is characterized by shallowly-buried Early-Jurassic coal seams,barely-reserved bedrocks and heavily-overlaid Quaternary porous sand aquifers, Quaternary aquifers of which poses great threat of water bursting a... |
