总结了国内外瓦斯/煤尘爆炸事故特点,研究了当前形势下瓦斯/煤尘爆炸作用下的灾害作用特性,揭示了瓦斯煤尘单一相、两相共混爆炸的结构动力响应机理及爆炸冲击波与结构间的耦合作用,对比分析了当前国内外爆炸结构相应问题的研究现状,探讨了瓦斯煤尘爆炸防控设备及装置动态安全性的研究方法,提出了瓦斯煤尘爆炸作用下结构动力问题的研究展望。研究工作对于煤矿瓦斯/煤尘爆炸致灾防控具有一定指导意义。
The characteristics of gas / coal dust explosion accident at home and abroad are summarized. The disastrous characteristics under the current situation of gas / coal dust explosion are researched. The dynamic response mechanism of single-phase and two-phase mixed explosion of gas and coal dust and explosion shock wave And the structure of the coupling between the comparative analysis of the current domestic and foreign explosive structure of the corresponding research status quo, gas and dust explosion prevention and control equipment and device dynamic safety research methods, proposed gas and coal dust explosion under the action of structural dynamics Research prospects. Research work for coal mine gas / coal dust explosion hazard prevention and control has some guidance.
