| 摘 要： | 运用RFPA2D—Flow固气耦合系统模拟了松动爆破抽放低透气性煤层内瓦斯的过程，解释了爆破松动是增加低透气性煤层透气性的有效途径，本文对松动爆破前后抽放过程中煤层内瓦斯压力和瓦斯渗流场的变化规律进行了数值模拟对比，为进一步理解瓦斯抽放、松动爆破增透机理等提供理论基础和科学依据。

| Abstract: | Using RFPA^2D-Flow stereo-gasses coupled system to simulate the process of gas draiange in lower air permeability coal seam by loose blasting,it interprets that loose blasting is a effective ways to increase air permeability in low air permeability coal seam. Both before and after loose blasting, the numerical simulation simulates the change law of pressure and gasses seepage field in coal seam very well,it provides fundamental basis and science evidence to gasses drawing , comprehend gasses drawing and antireflection mechanism by loose blasting and others. |
