Abstract

According to the different characteristics of coal spontaneous combustion (CSC), different countermeasures can effectively prevent CSC. In this paper, a new characteristic parameter, the oxygen consumption rate integral (OCRI), was proposed. The characteristics of CSC during the latent period and the effect of low oxygen concentration (0–20.96 %) on the CSC were comprehensively examined. Using a lab-built closed oxidation system, isothermal oxidation experiments were performed on different grades of coals at different temperatures. The OCRI was obtained by integrating the oxygen consumption rate as a function of oxygen concentration. The OCRI expresses the sum of the rates of oxygen consumption at different concentrations of oxygen and can be used as an identification index for the propensity of CSC. The kinetic basis for this approach is the variability of initial oxygen consumption rates and oxygen reaction orders for different coals. Finally, the physicochemical structure of the coal was measured by N2 adsorption and IR analysis. The results were correlated with the OCRI. On this basis, the main microscopic reaction pathways affecting the CSC were revealed. The results can aid in the future direction for research and development of high-efficiency inhibitors.
