摘要
以钻孔瓦斯径向不稳定流动理论为基础,从煤层钻孔周围煤体次生应力变化和煤体结构变形出发,阐明了煤体次生应力、瓦斯压力对钻孔周围煤层透气系数的影响。
Based on the theory of gas radial unstable flow in boring, it is investigated that permeability is affected by coal body, secondary stress and pressure in eoalseam on the basis of the secondary stress and deformation of coal body around boreholes in coal seam.
