Abstract

Based on the data by Xin-Wen Mining Group CO. LTD of Sun-Cun Coal Mine, the relationship between the geothermal gradient and the depth of mine in Suncun Coal Mine has been developed. According to this and the laboratory experiments, the relationship between the quantity of CO2 and the depth of coal mine has been obtained in this article. The results show that the curve on the period of time on spontaneous combustion of coal and the quantity of CO2 fit cubic polynomial expression in line. Especially when the quantity of CO2 produced exceeds 0.13 mol / (Kg • min), the period of time on spontaneous combustion of coal is unchanged. This law should be paid more attention to.
