煤尘爆炸的研究现状及发展趋势

煤尘爆炸是矿井热动力主要灾害形式之一。为明确煤尘爆炸的研究情况，防止煤尘爆炸事故的发生，总结了国内外对煤尘爆炸机理、爆炸特性、爆炸传播规律，以及煤尘爆炸抑制技术在理论、实验和数值模拟方面的研究现状，并对现阶段的煤尘爆炸研究提出了展望。分析表明：针对煤尘爆炸机理的研究处于热力学阶段，针对爆炸特性、传播规律的研究停留在宏观特征参数方面，抑爆措施有待改进，需加强对煤尘爆炸自主知识产权数值模拟软件的研发。

Research status and development trend of coal dust explosion

Coal dust explosion is one of the main forms of thermal power disaster in mine.In order to clarify the research situation of coal dust explosion and prevent the occurrence of coal dust explosion accident,this paper summarized the domestic and overseas research status of coal dust explosion mechanism,explosion characteristics,explosion propagation laws and coal dust explosion suppression technology in theory,experiment and numerical simulation.At the same time,the prospect of coal dust explosion was put forward.The results show that the study of the mechanism of coal dust explosion is in the thermodynamic stage,the study of coal dust explosion characteristics and propagation law remains in the macroscopic characteristic parameters,the anti-explosion measures need to be improved and the development of numerical simulation software for independent intellectual property rights for coal dust explosion should be strengthened.
