防治瓦斯突出的行之有效的方法之一就是预先抽放瓦斯，而影响抽放效果的主要因素是煤层的渗透性。通过对交叉钻孔的塑性强化区进行分析，对交叉钻孔的提高瓦斯抽放合理参数进行了探讨
One of the effective ways to prevent gas outburst is to pre-drain gas. The main factor that affects the drainage effect is the permeability of the coal seam. By analyzing the plastic reinforced zone of cross-borehole drilling, the reasonable parameters for improving gas drainage of cross-borehole drilling are discussed
