摘要
采空区积水是引发煤矿水害事故的主要原因。采空区积水酸度大,对井下轨道、金属支架、钢丝绳等金属设备有腐蚀作用。除此之外,采空区积水水压较大,一旦被掘透,涌水量特别大,且来势凶猛,极易造成严重后果。因此,必须高度重视采空区积水问题。探放水工作能够有效防范水害事故发生,本文主要分析了华宁焦煤有限责任公司井下充水性因素,提出了采空区积水探查方案及安全技术措施,可为今后煤矿安全生产、充水性分析及采空区探放水工作提供依据和指导。
Goaf water is the main reason for the accident of coal mine water. The acidity of goaf water is high,it can corrode metal equipment such as the underground roadway,metal supporting,wire rope and others. In addition,goaf water pressure is large,once the roadway is tunnelling through,water inflow is particularly large and ferociously,it is easy to cause serious consequences. Therefore,the problem of goaf water must be pay high attention.Water exploration and discharge can effectively prevent damage accident of coal mine water. This article mainly analyzes the coal mine water filling property and puts forward the exploring scheme and technical security measures of goaf water. It provides basis and guidance for coal mine safety production,water filling analysis and goaf exploring water.
