摘要
为真实掌握煤矿的涌水量和充水条件,在对煤矿水文地质分析的基础上,首先对充水条件和充水因素进行评价,得出煤矿的充水通道主要为导水裂隙带,基于层次分析得出通道条件的权重因子为 0.266 7 最大,为该煤矿的充水的首要条件;在对煤矿历年涌水量观测结果分析的基础上,采用大井法对涌水量进行预测,综合分析最终得出该煤矿正常涌水量为 462 m3/h,最大涌水量为 693 m3/h.
Abstract
In order to truly grasp the water inflow and filling conditions of coal mines,based on the hydrogeological analysis of coal mines,the water filling conditions and factors were first evaluated.It was found that the main water filling channel of the coal mine is the water conducting fracture zone.Based on the Analytic Hierarchy Process,the weight factor of the channel condition is 0.266 7,which is the highest,and is the primary condition for water filling in the coal mine.Based on the analysis of the observation results of the annual water inflow of the coal mine,the large well method was used to predict the water inflow.After comprehensive analysis,the normal water inflow of the coal mine was 462 m3/h,and the maximum water inflow was 693 m3/h.
