    Abstract
  • Gas explosion often occurs in the course of closing fired coal mine. The explosion limit and maximum explosion pressure under temperatures ranging from 25 ℃ to 200 ℃ and CO volume fractions of 1%−10% are studied by using a special 20 L explosive device. The results show that upper and lower explosion limits all decrease with increasing CO volume fraction, the range of explosion limit is widened in the presence of only CO. The upper gas explosive limit increases while its lower limit decreases as temperature increases. At ambient pressure, the upper gas explosive limit increases quadratically with initial temperature while the lower limit increases logarithmically with initial temperature. Increasing CO volume fraction results in increase in both the upper pressure limit and the lower pressure limit. Coupling CO gas with high temperature, the gas explosive upper limit increases and the lower limit decreases thus higher risk is expected in such condition. Explosive limits, especially the upper limit are more sensitive to coupling factors than to single factor.
