Study on water-rich roof of coal seam based on fracture prediction and fluid prediction technology——taking the two coal seams of Gequan Mine as an example
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 Wu-liuqi 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.
