摘要
分析了采动空间空隙介质和瓦斯运动的特性.提出采动空间瓦斯运动的双重介质模型.与单一空隙介质模型的微分方程相比.能更好地描述实际瓦斯运动。
A double-mediun model of gas movement in mining influence space (MIS) is advanced byanalysing the feature of gap medium and gas flow in mining influence space. The model can discribereal gas movement law better than single-medium model.
