Abstract

Coal spontaneous combustion (CSC) is the combustion of the outcrop or shallow part of a coal seam due to long-term oxidation or artificial factors. Because of the continuous development of surface cracks, oxygen is constantly transported to the high-temperature zone, promoting diffusion to the deep coal seam. This study independently established a semi-closed experimental system. Coal samples from Lu'an, Shanxi Province, China were selected as the research objects, and 15 points were established in the coal seam to probe the law of temperature change to determine the high-temperature zone. It further revealed the distribution law of oxygen and gaseous products in the high temperature region during CSC. Finally, various index systems were determined. The results show that CO, CO2, CH4, and C2H4 gas concentrations increased during the heating stage and decreased during the cooling stage. Furthermore, there are “mutation” processes and “delay” in the points between the same layers of various gases. The determination indices in the heating stage were φ(CO)/φ (CO2), Graham number, and Grignard fire coefficients R2 and R3. In contrast, the cooling stages were φ(C2H4)/φ (CH4), Graham number, and Grignard fire coefficients R1 and R2.
