Advances in the study of hydrogeochemistry of karstic groundwater in coal mines in North China

文章总结了水文地球化学在分析浅层煤田岩溶水化学特征、建立判别矿坑突水水化学模式、研究矿坑水形成机理以及制定矿区水资源管理和环境保护对策等多方面的应用效果。根据煤田深部开采"三高一扰动"的复杂环境的采矿条件,深部水文地球化学环境表现出岩溶水三维水流系统发育、地下水储量大、水头高、补给广、径流长、水源温度高的特点,建议应用水文地球化学理论、方法研究深循环岩溶水的运动规律、深部岩层与富水性关系、煤田深部地下水水化学特征及其形成机制。

Hydrogeochemical data were applied in analyzing the characteristics of karstic groundwater in coal mines in North China, distinguishing water outburst sources, examing the formation mechanism of groundwater in mining areas, and planning the protection of environment and water resources management. However, there are three ＂high＂ and one ＂disturbance＂, i.e., high ground stress, high earth temperature, high karst water pressure, and mining disturbance in deep mining. Therefore hydrogeochemical environments change under the conditions of high pressures of rock and groundwater, high temperatures of rock and groundwater and long runoff of groundwater. Due to complicated conditions in deep mining, it is pointed out that chemical characteristics and recycle of deep groundwater and relationships between deep rocks and water yield property must be considered with theory and method of hydrochemistry.
