三交河煤矿水文地质条件及矿井充水因素分析

三交河煤矿是霍州煤电集团主干矿井,随着矿井开采水平的延伸和开采强度的增加,矿井受水害威胁程度越来越大。分析了矿井水文地质条件及含水层和隔水层分布规律和特征;利用导水裂隙带发育高度计算结果,对各开采煤层顶板充水进行了分析评价;由于矿井煤层埋藏较浅,矿井受古窑、小窑水害威胁程度较为严重,对各煤层受小窑水和采空区水充水进行了分析评价。对矿井做好防治水工作,安全经济开采煤炭资源提供了参考。

Analysis on Hydrogeology Condition and Water Filling Factors in Sanjiaohe Coal Mine

Sanjiaohe Coal Mine is the main coal mine in Huozhou Coal Electricity Group.With extension and the greater intensity of mining,the threat from water damage is increasing.The hydrogeology condition of the mine and the distribution and characteristics of aquifer and aquifuge are analyzed.Based on the caculation results of the height of water conductivity fracture zone,the water filling property of the roof in each coal seam is analysed and evaluated.Due to its shallow buried depth,ancient and small coal kilns are subjected to water damage more seriously.So analysis and evaluation is made for the water filling from ancient and small coal kilns and goaf for each coal seam.The paper provides good reference for mine water prevention and exploitation of coal resources more safely and economically.
