Evaluation of Coal Mine Water Filling Factors and Prediction of Water Inflow
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.
