Study on Landmark Gas for Unsealed Layered Fire Area in Two-hard Coal Seam

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 , C2 H2 and O2 in the coal sample of same place are the same variation.O2 can be used as landmark gas in the incubation period of coal spontaneous combustion, CO, CO2, C2 H4 and O2 can used as landmark gas in the heat period, and CO, CO2, C2H4, C2H2 and O2 can used as landmark gas in the coal combustion stage.
