The determination of coal seam gas content is of great significance to the study of coal seam gas occurrence law and gas prevention technology. There are direct and indirect methods for the determination of gas content in coal seam. Both direct and indirect methods have their advantages and disadvantages, but the results of direct measurement have more disadvantage than indirect measurement. In this paper, the gas content in No. 1 coal seam of Weijiadi Coal Mine is determined by indirect measurement method. The gas content in No. 1 coal seam is calculated to be 8.1m3/t, which is important for gas geological division and precise gas extraction.
