摘要
瓦斯抽采效果的优劣直接关系到工作面瓦斯抽采时间的长短,进而影响到整个矿井工作面的接替。文章采用数值模拟的方法分析钻孔直径对瓦斯抽采效果的影响,为瓦斯抽采效果的提升提供科学的依据,对缓解矿井工作面接替紧张局面具有重要价值。
The merits of gas extraction effect is directly related to the duration of gas drainage, thereby affecting the entire mine face to succeed. In this paper,the numerical simulation is used to analysis the effect of gas drainage under different hole diameter,to provide a scientific basis for enhance the effect of gas drainage, there is great value in relieving tensions of mine face to succeed.
