备注

为了更科学合理地布置矿井紧急避险系统,以瓦斯煤尘爆炸为例,引用炸药爆炸规律将瓦斯煤尘爆炸的伤害划分为非常严重区、严重区和轻微区; 运用爆炸超压值衰减理论、热辐射伤害准则和毒物-浓度伤害准则,建立了矿井瓦斯煤尘爆炸三区伤害范围划分准则; 结合瓦斯煤尘爆炸的特点及不同紧急避险设施的优缺点,对井下避险设施的合理位置和类型进行了探讨。结果 表明:非常严重区和严重区以冲击波伤害为主,轻微区以有毒有害气体伤害为主; 在非常严重区设置避难设施对瓦斯煤尘爆炸事故无效; 在严重区中部应设置抗爆性较高的可移动救生舱; 在轻微区内宜设置密闭性较强的避难硐室。

In order to arrange coal mine emergency refuge system more scientifically and more reasonably,taking mine gas and coal dust explosion accidents as an example,the law of explosive detonation is referenced to divide injury regions into very serious region,serious region and gentle region.Used the attenuation theory of explosion overpressure,the injury criterion of thermal dosage and poison-concentration,the criterion of range classification of three regions is given.Combined with the characteristics of gas and coal dust explosion and the advantages and disadvantages of different refuge facilities,we study the reasonable position and types of the emergency refuge installations.The results show that the very serious region and the serious region are subject to blast wave,and the gentle region is subject to poisonous gases.And refuge facilities don't work in very serious region.And movable rescue chamber with strong explosion-proof should be set in the middle serious region.And refuge chamber with good airtightness should be set in the gentle region.
