以白杨沟煤矿瓦斯爆炸事故为研究背景,采用数值模拟的方法分别建立不同巷道拐角、不同瓦斯填充长度时的数值计算模型,分析火焰传播速度与巷道拐角、巷道内瓦斯填充长度之间的关系,得到瓦斯爆炸火焰在通过巷道拐角时的传播规律。对有效、全面预防矿井瓦斯爆炸事故、降低瓦斯爆炸事故造成的损失及瓦斯爆炸事故调查取证具有非常重要的指导意义。
Taking the gas explosion accident in Baiyanggou coal mine as a research background, numerical simulation models were established to simulate the different corners and different lengths of gas filling, and the relationship between the flame propagation velocity and the corner of the roadway and the gas filling length in the roadway was analyzed. Get the gas explosion flame propagation angle at the corner of the road. It has very important guiding significance for the effective and comprehensive prevention of gas explosion accidents in mines, the reduction of losses caused by gas explosion accidents and the investigation and evidence collection of gas explosion accidents.
