Based on the coal seam samples test results and coal mine exploration data,the gas geological characteristics of Wangjiazhai Coal Mine in Zhongshan District,Liupanshui City,Guizhou Province were analyzed.The research results indicate that all minable coal seams in the area are high-gas coal seams.The gas content in these coal seams is relatively abundant,showing a gradually increasing trend from the northwest to the southeast.There is a risk of gas outburst in coal seams,necessitating preventive measures during production.The coalbed methane geological reserves in the research area are small,with moderate geological reserves abundance.
