Coal Spontaneous Combustion Landmark Gas Analysis and Optimization
CO as a symbol of gas to predict coal spontaneous combustion standard in our country were obtained and widely used but CO testing temperature range very wide, index of the forecast range is too big, not accurate judgement the temperature parameters. Therefore, the need to carbon monoxide index, index and analysis the change of C2H6/ CH4 , C3Hg/ CH4 in coal natural oxidation process.Through analysis, we can know CO can be used as a prediction of the coal spontaneous combustion gas index; C2 H4 gas can be regarded as the oxidation of the coal into oxidize quickly phase of the mark; C3 H6 gas can be regarded as the oxidation of the coal into fierce oxidation phase of the sign.
