瓦斯煤尘爆炸特性及传播规律研究进展

Research Progress in Explosion Characteristics and Spread Law of Gas and Coal Dust

概要介绍国内外的瓦斯爆炸和瓦斯煤尘混合物爆炸特性及传播规律研究进展,瓦斯爆炸研究主要集中在瓦斯爆炸压力、火焰、温度等特征参数、不同障碍物对瓦斯爆炸压力、火焰传播的影响以及分岔、拐弯等不同形状管道内的传播规律,而瓦斯煤尘混合物爆炸研究主要集中在瓦斯对煤尘爆炸的最小点火能、爆炸下限、最大爆炸压力等爆炸特性及传播规律的影响。对不同研究人员采用的主要研究指标、手段、方法和研究结论进行综合评述,同时也对爆炸事故人员伤害模型在国内外的研究状况进行讨论,最后指出目前存在的主要问题和下一步的研究方向。

The paper classified gas and coal dust explosion into gas explosion and gas and coal dust mixture explosion, and discussed their research progress in explosion characteristics and spread law respectively. Gas explosion research mainly focused on gas explosion characteristics （such as pressure, flame, temperature and so on）, barrier＇s influence on gas explosion pressure and flame spread and spread law of gas explosion in fork and bend pipeline. Gas and coal dust mixture explosion research mainly focused on the influence of gas on the coal dust explosion＇s characteristics （ such as minimum ignition energy, lower explosion limit, maximum explosion pressure and so on） and spread law. Finally, the paper made a review of the main research indexes, ways, methods and research results in this field, discussed the research progress in personnel injury model in explosion accidents at home and abroad, and pointed out the current problems and further research directions in this field.
