Research And Application On Testing System And Characteristic Gas Of The Coal Spontaneous Combustion

The spontaneous combustion of coal seam is one of the major calamities in safe production of coal mine. The key factors of occurrence and development of coal self-ignition is quantity of heat that is produced by coal spontaneously. Therefore, studying the coal exothermic property is the precondition of mastering the process of coal self-ignition, searching the law for it and developing coal seam fire prediction. In the paper, the research of characteristic parameters of coal spontaneous combustion is the precondition of coal seam fire prediction and disposal. Characteristic parameters of coal spontaneous combustion-exothermicity were researched to a certain extent by the methods of theoretical analysis, experiment simulation and development of application software. Therefore the research provides theoretics for coal exothermic property in factual condition. Characteristic parameters of coal spontaneous combustion were qualitatively studied and quantitatively determined by coal self-ignition experiment from two aspects: coal oxidation and exothermic which is produced by oxidation.
