摘　　要：为了查清葛泉矿五六七采区和葛泉东井两个区块2煤顶板富水特征,在已知地质构造和高物性地层空间展布的基础上,采用裂缝预测技术对不同尺度裂缝进行研究,同时采用高频衰减梯度进行流体预测,进而对煤层顶板富水性进行了预测。结果表明:葛泉矿五六七采区顶板富水区主要集中在中西部地区,葛泉东井整体富水性差。该研究成果可对葛泉矿2煤层顶板富水性预测提供依据,在开采过程中,对重点区域提高警惕,能有效预防水害事故的发生。In order to find out the characteristics of rich water in 2 coal seam roofs in the Wuliuqi mining area and Gequan East well,based on known geological structure and spatial distribution of high physical strata,the fracture prediction technique is used to study the fracture of different scales.At the same time,a high-frequency attenuation gradient is used to predict the fluid,and then the water-rich roof of the coal seam is predicted.The results have shown that the roof water-rich area of the Wuliuqi mining area of Gequan Mine is mainly concentrated in the central and western regions,and the water-rich area of Gequan East well is poor.The research results can provide a basis for predicting the water abundance of 2 coal seam roofs in Gequan Mine.In the process of mining,the key areas should be vigilant to prevent the occurrence of water accidents effectively.
