阳泉二矿矿井水致灾类型及影响程度分析

Analysis on the Types and Influence Degree of Mine water Disaster in Yangquan No.2 Coal Mine

矿井水灾害是影响矿井安全生产的重要因素之一,文章基于水文地质、构造地质、物探及采矿等资料,采用地质及水文地质理论对阳泉二矿水灾害类型及影响程度进行了分析。结果表明:地表水、采空区积水、含水层水、构造水及封闭不良钻孔水是构成该矿矿井水灾害的主要类型,不同矿井水灾害类型形成、致灾机理、致灾特点及影响程度各不相同。针对矿井水类型差异,采用合理的防治水措施是提高矿井水灾害防治水平的关键。

Mine water disaster is one of the important factors affecting mine safety. Based on hydrogeology, tectonic geology, geophysical exploration and mining data, the author used geological and hydrogeological theory to analyze the types and effects of water disasters in Yangquan No.2 Coal Mine.The results show that: surface water, water in the goaf, aquifer water,structural water and poorly sealed borehole water are the main types of mine water that constitute the mine water disaster in the study area.The formation of different mine water disasters,the mechanism of disasters, The characteristics of the disaster and the degree of impact vary.In view of the difference in mine water types, the use of reasonable water control measures is the key to improving the level of mine water disaster prevention.
