瓦斯爆炸实验研究进展及展望

摘要

瓦斯爆炸事故是煤矿的主要灾害之一,为了预防和控制煤矿井下瓦斯爆炸事故的发生,国内外研究者采用理论、实验室实验和数值模拟实验等手段对瓦斯爆炸机理、瓦斯爆炸传播规律等进行了深入研究,本文从瓦斯爆炸实验室实验和瓦斯爆炸数值模拟实验两方面入手,对瓦斯爆炸的研究进展情况进行了分析总结.对于瓦斯爆炸实验室研究,分析总结了现有瓦斯爆炸实验手段以及瓦斯爆炸传播特性研究情况；对于数值实验研究,分析总结了瓦斯爆炸数值模拟模型、现有瓦斯爆炸数值模拟商业软件以及软件应用情况.最后对瓦斯爆炸未来需要深入研究的问题提出了展望.%Gas explosion is a main disaster of coal mine. In order to prevent and control gas explosion of coal mine, mechanism and propagation law are studied using the method of theoretical research, experiment and numerical simulation. In the paper, research status and development direction of gas explosion at home and abroad in recent years are introduced from experiment and numerical simulation. On experiment, experiment method and propagation characteristics of gas explosion at home and abroad in recent years are introduced in the paper. On numerical simulation, numerical simulation model, commercial software and application of the software are summed up and analyzed. In the end, the existing problem and developing direction of gas explosion are pointed out in the paper.
