摘　　要：以煤层自然发火标志气体及临界值检测工作为研究对象进行了分析。自然发火是煤炭开采过程中最为严重的灾害之一,其特点是能量大、速度快、持续时间长。由于受自然条件和煤层赋存状态等因素的影响,在开采过程中自然发火现象时有发生。因此,开展煤自燃特征气体研究工作,可为预防和治理工作面煤炭自燃灾害提供科学依据。基于此,介绍了煤层自然发火标志气体测定原理和优选原则,分析了标志气体测定的实验方法,并且探索了气体的临界值检测工作要点,以保证煤炭开采工作的安全和稳定。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.
