This study presents the solution of the extraction and coal seam. Through the combination of numerical simulation study and field investigation, the fracturing radius is 12 meters after 30 days of hydraulic fracturing in the 6th coal seam, and the implementation measures of fracturing hole spacing of 20 meters and 5 meters were formulated. The results showed that the hydraulic fracturing technology significantly increased the gas concentration of drilling extraction to 93%, and the attenuation rate of gas concentration in 120 days was 14%. This technology has significantly increased the extraction flow, and effectively controlled the occurrence of coal seam fire. The methods and results of this study are instructive for coalbed methane utilization in other mines.
