山东省金阳煤矿矿井水文地质特征分析及涌水量预测

摘要

In this paper,hydrogeological characteristics and water filling factors of Jinyang coal mine have been analyzed.It is thought that direct water filling source of No.2 and No.3 coal layers are sandstone pore fissure aquifer in the roof of No.3 coal layer in Shanxi group.Through analysis and research on hydrologi-cal observation data and hydrological geology drilling hierarchical datas in many years,by using the"anal-ogy method",water inflow amount has been predicated,normal water inflow amount and the maxmium water inflow amount have been determined.It will provide scientific basis and examples for similar re-search in mines.%该文分析了金阳煤矿矿井水文地质特征及充水因素,认为该矿井开采2,3煤层的直接充水水源为山西组3煤层顶板砂岩孔隙裂隙含水层。通过分析研究井下多年水文观测数据和水文地质钻孔分层抽水试验获取的基础数据,采用“比拟法”对矿井涌水量进行了预算,确定出矿井的正常涌水量和最大涌水量,为矿井今后生产提供了科学依据,也为同类研究提供了实例。
