西曲煤矿水文地质类型划分探讨

矿井水文地质类型划分,对煤矿的安全生产划分有着重要的意义。探讨西曲煤矿矿井水文地质类型的划分,对井田内水文地质条件及矿井充水因素进行分析,得出该矿开采受水害影响程度以及防治水工作开展的难易程度均为中等。具体为,2+3#煤层矿井水文地质类型为中等,4#煤层矿井水文地质类型为复杂,8#、9#煤层矿井水文地质类型为复杂。分析认为,该矿应加强对陷落柱的物探和钻探、本矿采空积水探放水、矿界防隔水煤柱的留设等工作,研究结果可为煤矿防治水工作提供依据,在一定程度上可确保矿井安全生产。

Discussion on the classification of hydrogeological type in Xiqu Coal Mine

The classification of mine hydrogeological type is of great significance to the safety production in coal mines.In order to explore the mine hydrogeological type in Xiqu Coal Mine,by analyzing the hydrogeological conditions and water filling factors in the minefield,the degree of mining affected by water disaster and the difficulty of water prevention and control were discussed.The results show that the hydrogeological type of No.2+3 coal seam is medium,No.4,No.8 and No.9 coal seam are complex.Based on the analysis,the paper puts forward some measures of strengthening the geophysical exploration and drilling of collapse columns,the water exploration and drainage of goaf water,and the retention of the waterproof coal pillars,which can provide the basis for the prevention and control of water in the coal mine and ensure the safety production of the coal mine to a certain extent.
