英文摘要: Application of physical and chemical test methods, analysis of the chemical structure of different types of coal, to establish the characteristics of the coal structure model; application of theoretical and experimental methods of systematic study of the mechanism of coal and oxygen adsorption, chemical reaction mechanisms to prevent spontaneous combustion of coal-based inerting mechanism of resistance, spontaneous combustion process due to the interaction mechanism of internal and external, to reveal the nature of law and the evolution of coal spontaneous combustion mechanism, establish a new theory of the mechanism of coal spontaneous combustion. Application of ignition new theory, combined with the TGA experiments, the establishment of the fire to determine the activation energy of coal spontaneous combustion theory and the difficulty to determine the difficulty of the new coal spontaneous combustion methods, techniques and indicators; gas interaction with the hazard of spontaneous combustion mechanism, revealing oxygen and coal , the three hazard occurrence and development of gas evolution, warning gas explosion suppression technology parameters; application of percolation theory and mass transfer, heat transfer theory coal (mining) mechanism of spontaneous combustion of coal disasters play raw, spontaneous
