Relationship Analysis Between Granularity and Volatile of Coal and Residual Gas Content of Coal

Based on the principle of coal gas adsorption, through site sampling in the domestic part mining area, the determination of the residual gas content of coal is carried out in the laboratory, the relationship between coal granularity, volatile and coal residual gas content is analyzed, which provides technique support for the prediction of mine gas emission and the determination of coal seam residual gas quantity.
