近年来,随着矿井开采向地层深处不断延伸,地层地质及水文地质条件愈加复杂,突水淹井事故呈现出上升趋势,严重影响矿井安全生产。依据矿井充水水源及水源进入矿井的途径和方式,矿井水害可划分为五种,即地表水水害、老窑水水害、孔隙水水害、裂隙水水害及岩溶水水害。加强矿井水的探测和疏放工作,提高技术和管理水平,采取相应的矿井防治水措施,是降低煤矿水害事故的必要条件。
In recent years, with the extension of mine exploitation to the depths of strata, the geological and hydrogeological conditions of strata have become more and more complicated. The accidents of flooding in flooding show an upward trend, which seriously affects mine safety production. According to the ways and ways of mine water supply and water source into the mine, mine water damage can be divided into five kinds, namely surface water damage, old water pollution, pore water damage, fissure water damage and karst water damage. Strengthening mine water exploration and dredging efforts to improve the technical and management level, to take appropriate measures to prevent and control mine water is to reduce coal mine water damage necessary conditions.
