煤矿瓦斯煤尘燃烧与爆炸研究现状及展望

摘要

Gas and coal dust explosion is one of the coal mine disaster. In order to prevent and control gas and coal dust explosion in coal mine, the domestics and overseas researchers have applied theories, experiments and numerical modeling to study the ignition characters of gas and coal dust, laws of gas and coal dust composite flame propagation and participation in the gas explosion induction of deposited coal dust explosion. In this paper, a comprehensive review is given about the domestic and foreign research results in the research direction. And it prospects the concerns of gas and coal dust explosion in the future research direction.%瓦斯煤尘爆炸事故是煤矿灾害事故之一，为了预防和控制井下此类事故的发生，国内外研究者采用理论分析、实验研究和数值模拟等手段对瓦斯煤尘着火特性、瓦斯煤尘复合火焰传播规律及瓦斯爆炸诱导沉积煤尘参与爆炸等进行了深入的大量的研究，本文对该研究方向上的国内外研究成果进行了综合评述，并展望了瓦斯煤尘爆炸未来科研方向上的关注点。
