武所屯煤矿12煤老空积水区水文地质参数研究

Study on Hydrogeological Parameters in Working-out Section of No.12 Coal Setion in Wusuotun Coal Mine

摘要:

通过该矿12煤老空积水的疏放试验，选取相应的数学模型，计算了太原组12煤老空积水区的水文地质参数——渗透系数、充水系数；为滕北矿区类似条件下的老空积水疏放提供了理论依据。根据试验提出了利用集水廊道原理，扩大钻孔涌水量，节约工程费用，提高疏放效率的工程设计方法。

Abstract:

Through draining water practice of No.12 coal section in Wusuotun coal mine, choosing relative mathematical model, hydrogeological parameters including hydraulic conductivity and water filling coefficient of working-out section of No.12 coal seam were calculated in this paper. The research results can provide theoretical foundation for draining water from the working-out section to the coal mine with the same condition in Tengbei mining area. By using the theory of drainage galleries ,an engineering design method was put forward in this paper. It can improve the flow rate of well, the efficiency of water drainage and save engineering cost.
