为建立工作面上隅角CO气体浓度的定量计算模型,以煤氧化过程中CO气体产生机理为理论依据,分析了开采工作面CO气体来源及影响因素,综合煤自燃的内因和外因条件,以采空区煤自燃"三带"分布参数和煤自燃氧化特征参数为计算依据,建立了工作面上隅角CO气体浓度值的计算模型,并应用该模型对灵武矿区不同回采工艺工作面上隅角CO气体浓度进行了计算,计算参数和实测值相比其相对误差在12%以内。

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%.
