摘要:
为研究高海拔矿井瓦斯爆炸火焰传播规律，运用数值模拟方法，建立矿井掘进巷道瓦斯气体爆炸数学及物理模型，并对海拔高度为0，1 000，2 000，3 000，4 000 m时的爆炸火焰传播速度、温度和冲击波压力进行研究。结果表明：瓦斯浓度和聚集体积量一定的掘进巷道发生瓦斯爆炸时，随着海拔高度的升高，火焰传播速度增大，且海拔每升高1 000 m，瓦斯气体聚集区和非聚集区的平均火焰传播速度分别增大4.7%和1.9%，掘进巷道内同一位置受到的瓦斯爆炸火焰最高冲击波压力随着海拔高度增加而显著降低，且呈二次函数关系，达到最大冲击波压力和最高火焰温度的时间缩短，最高爆炸火焰温度受海拔高度的影响较小。
Abstract:
In order to study the flame propagation laws of gas explosion in the high altitude mines,a numerical simulation method was used to establish the mathematical and physical models of gas explosion in the excavation roadway of mine,and the explosion flame propagation speed,temperature and shock wave pressure at the altitude of 0,1 000,2 000,3 000 m and 4 000 m were simulated and studied.The results showed that when the gas explosion occurred in the excavation roadway with a certain gas concentration and accumulated volume,the flame propagation speed increased with the increase of altitude,and every time the altitude increased by 1 000 m,the average flame propagation speed in the gas accumulation area and nonaccumulation area increases by 4.7% and 1.9%,respectively.The maximum shock wave pressure of the gas explosion flame at the same location in the excavation roadway decreased significantly with the increase of altitude,which presented a quadratic function relationship.The time to reach the maximum shock wave pressure and maximum flame temperature were shortened comparatively,and the maximum explosion flame temperature was less affected by the altitude.
