英文摘要: In order to accurately and rapidly distinguish the water inrush source in Xieqiao Coal Mine, the hydrogeological characteristics of the aquifer affecting the production of the coal mine are de-scribed. The hydrochemical characteristics of the coal-bearing sandstone aquifer (roof sandstone aquifer, floor sandstone aquifer) and Taiyuan limestone aquifer in the aquifer are sampled and analyzed; based on the difference of the hydrochemical characteristics of HCO3-, Cl−, SO42-, Ca2+, Na+, K+, Mg2+, total hardness and water quality type, etc., methods are presented to distinguish the source of mine water inrush by combining ionic milligram equivalent percentage, tree graph of systematic cluster analysis and total hardness. Research and analysis show that the three methods can be used to...
中文摘要: 为了准确与快速地判别出谢桥煤矿突水水源,对影响该煤矿生产的含水层水文地质特征进行阐述,采样分析含水层中的煤系砂岩含水层(顶板砂岩含水层、底板砂岩含水层)和太原组灰岩含水层的水化学特征,基于HCO3-、Cl−、SO42-、Ca2+、Na+、K+、Mg2+等主要离子含量、全硬度与水质类型等水化学特征的差异,提出离子毫克当量百分数、系统聚类分析树状图与全硬度等结合对矿井突水水源进行判别的方法。研究分析表明,采用这2种方法对谢桥煤矿突水水源能够进行准确与快速地判别。可为煤矿安全生产与进一步采取有效的防治水措施提供相关的指导。
