  • In order to establish a quantitative calculation model of CO gas content at the upper of the coal mining face, based on the CO gas produced mechanism from the coal oxidization process as the theory basis, the CO gas sources and influence factors of the coal mining face were analyzed.In combination with the internal a nd external cause conditions of the coal spontaneous combustion, based on the distribution parameters of the coal spontaneous combustion in the goaf and the coal sp ontaneous combustion oxidization feature parameters as the calculation basis, a calculation model of the CO gas content value at the upper corner of the coal mining fa ce was established .And the model was applied to the calculation of the CO gas content at the upper corner of the coal mining face with different coal mining methods in Lingwu Mine.The error between the calculation parameters and site measured value was within 12%.
