摘要
运用流体力学和传质理论.提出了描述矿并大气中瓦斯迁移运动的数学模型;分析了几种出现积聚层情况下的瓦斯迁移机理和主要参数选取.并给出了求解微分方程组的数值方法。
general mathematical model describing migration motion of gas in mine air is advanced with fluid mechanics and diffusion theory. The mechanism of gas migration under the condition of gas accumulation is analyzed and the main Parameters are determined. Then the numerical solution of the equation group is gained.
