摘要
The temperature - programmed experiments are used to study the landmark gas for unsealed fire area, and fuzzy mathematics is used to prefer the unsealed landmark gas, the results show that: the gas concentrations and temperature of CO, CO2, C2H4, C2H2 and O-2 in the coal sample of same place are the same variation. O-2 can be used as landmark gas in the incubation period of coal spontaneous combustion, CO, CO2, C2H4 and O-2 can used as landmark gas in the heat period, and CO, CO2, C2H4, C2H2 and O-2 can used as landmark gas in the coal combustion stage.
