煤炭自燃是煤矿的主要灾害之一。不仅烧毁宝贵资源，还严重危害井下工作人员的安全与健康。CO2气体灭火可以应用于矿井的防灭火工作。煤矿井下的气体是多种气体的混合物，煤对很多种气体具有吸附特性。运用量子化学理论高斯03软件包对二氧化碳气体在煤表面吸附时，甲烷气体对其吸附能力的影响进行研究。结果表明，当煤表面分别吸附1个和2个CO2分子时，有1个CH4分子存在会促进煤表面吸附CO2分子。但当CO2分子的个数大于2个时，有1个CH4分子存在就会抑制煤表面吸附CO2分子。因此，CH4分子对煤表面吸附CO2分子是有影响的。甲烷气体的含量能够影响煤对二氧化碳气体的吸附。

Coal spontaneous combustion is one of the main disasters in coal mine. Not only burned precious resources, but also it serious harm work personnel's safety and health. CO2 gas fire extinguishing can be applied to the mine fire prevention work. Mine gas is a mixture of gases. For a variety of gas coal is absorbing coal to a variety of gas has adsorption characteristics. Using quantum chemistry theory Gaussian 03 package, research of CH4 gas influenced adsorption ability in coal surface of CO2 gas. The results showed that, when the coal surface adsorption respectively 1 and 2 CO2 molecule, a CH4 molecular existence will promote coal surface adsorption CO2 molecule. But when CO2 molecular number greater than 2, 1 CH4 molecular existence will inhibit coal surface adsorption CO2 molecule. Therefore, CH4 molecule on coal surface adsorption CO2 molecule is an influence. Methane gas content can affect coal of carbon dioxide gas adsorption.
