Analysis on the Laws of Spontaneous Combustion Index Gases and Their Influencing Factors in Wenzhuang Coal Mine

Building the coal spontaneous combustion index gases programmed temperature experiment table,the paper studied the impact of coal gas produced laws in the temperature-programmed experiments when the experimental conditions changed,such as the experimental initial temperature,temperature-programmed rate,dry air flow,coal sample size and the weight of coal sample etc.The initial temperature was regard as the critical factor,the temperature-programmed rate and the weight of coal sample took the second place.
