基于瓦斯涌出分源预测选择瓦斯抽放方法的研究

Study on choice of gas drainage method based on different-source gas emission prediction of working face

煤矿瓦斯抽放是瓦斯治理、降低瓦斯涌出量的有效方法和手段,要充分发挥瓦斯抽放的效用就必须合理选择抽放方法。利用瓦斯分源涌出预测的结果,按照瓦斯分源治理的思想,研究一种选择瓦斯抽放源的分析方法,避免生产中单纯依靠经验选择瓦斯抽放方法的传统模式,以改善抽放效果,提高矿井瓦斯事故防治水平,为安全生产提供保障。

Gas drainage is a kind of effective method to control gas. To choose reasonably gas drainage method is very important to give the effect of gas drainage. Based on the results of different - source gas emission prediction of working face, an analysis method is studied to ascertain the gas drainage source in this paper, to avoid choosing a gas drainage by experience. The effect of gas drainage can be improved.
