An analysis was conducted on the detection of significant gases and critical values for coal seam spontaneous combustion.Spontaneous combustion is one of the most serious disasters in coal mining,characterized by high energy,fast speed,and long duration.Due to factors such as natural conditions and the occurrence of coal seams,spontaneous combustion often occurs during the mining process.Therefore,conducting research on characteristic gases of coal spontaneous combustion can provide scientific basis for preventing and controlling coal spontaneous combustion disasters in working faces.Based on this,the principles of measuring and selecting significant gases for coal seam spontaneous combustion were introduced,the experimental methods for measuring significant gases were analyzed,and the key points for detecting the critical value of gases were explored to ensure the safety and stability of coal mining work.
