| 摘 要： | 论述三维应力作用下煤体瓦斯渗透规律的实验设备与方法。介绍了阳泉３＃煤层、永红煤矿３＃煤层的试验结论。得出了煤体瓦斯渗透系数随体积应力增加而衰减，随孔隙压呈抛物线型变化。定义抛物线的极值点为临界压力。结论对研究煤矿瓦斯抽放与瓦斯突出有着十分重要的意义

| Abstract: | This paper expounds the experiment equipment and method of the permeating law of coal mass gas under actign of 3 dimension stress.The experimrntal conclusion of 3 # coal of Yangquan and 3 # coal of Yonghong is introduced. The coefficient of permeability of coal massgas attenuates with increase of volume stress and varies as parabola with porous pressure. The crtical pressnre is difinedas the extreme value of parabola. The conclusions are important to the study of drawing out gas and gas burst. |
