开平煤田宋家营勘查区煤层开采充水因素分析
Kaiping Coal Seam Exploitation SongGuYing Exploration District Water Filling Factor Analysis
摘要
通过对宋家营勘查区的水文地质条件、含隔水层特征、地下水动态及各含水层之间的水力联系等因素的分析.为矿井开采水害防治提供参考资料和决策依据。影响煤层开采主要直接充水含水层为各主要可采煤层顶、底板及煤层间砂岩含水层,上第三系底部半胶结砂、砾岩仅在局部为直接充水含水层。奥灰含水层上距12煤层144.38~150.81m,其间有厚层粉砂岩、泥岩隔水层,正常情况下,奥灰水不会对煤层开采构成威胁,结合邻区钱家营矿井水文地质资料对比,勘查区矿床水文地质类型除断层导水外为水文地质条件中等的裂隙(局部孔隙)充水矿床,即:二
