Study on mine water inflow characteristics and water disaster prediction in Anshan Mine
As one of the main producing areas of coal in China,it was an urgent problem to realize the rational mining of coal and the prediction of mine water inflow in northern Shaanxi mining area.In order to study the problem of mine water inflow in Anshan Mine,the mine water inflow and the height of water conduction fracture zone were studied by means of field measurement and theoretical prediction.The research showed that there was a peak point in the mine water inflow of No.5-2 coal mining in Anshan Mine,and the maximum value was 58.5 m3/h.The overall trend was in a slow growth trend,and the water inflow was mainly affected by the mining parameters of the working face.The maximum water inflow of the mine was 94.59 m3/h,which was obtained by the theoretical prediction method.Combined with the formula of water conduction fracture height,it was predicted that most of the coal seam mining areas were not connected with the upper coal seam,and only some areas were connected.Through drilling exploration in field,it was found that the theoretical prediction was similar to the field measurement results.According to the geological conditions of the mine,a targeted geological guarantee measure for mine water inflow was proposed.
