煤矿含障碍物的瓦斯爆炸数值模拟研究综述

Summarization of numerical simulation of gas explosion with obstacles in coal mine

煤炭资源在能源结构中一直占有重要的地位,煤矿瓦斯爆炸事故是最严重的事故之一,往往会造成严重的财产损失和人员伤亡,障碍物的存在增加了瓦斯爆炸的危险性,本文试图通过对前人含障碍物瓦斯爆炸实验和数值模拟研究的结果进行分析,总结出瓦斯爆炸现象研究的现状,通过对前人研究的局限性和展望找出开展障碍物对瓦斯爆炸影响研究的思路,寻找爆炸数值模拟的多种路径,为以后开展大量的数值模拟提供支持,也为科研人员开展工作提供数据资料。

Coal resources have always played an important role in the energy structure.Coal mine gas explosion accident is one of the most serious accidents,which often causes serious property losses and casualties.The existence of obstacles increases the risk of gas explosion.This paper attempts to summarize the research status of gas explosion phenomenon by analyzing the results of previous gas explosion experiments and numerical simulation studies with obstacles.Through the limitations and prospects of previous studies,this paper finds out the ideas of carrying out the research on the influence of obstacles on gas explosion,and looks for a variety of paths of explosion numerical simulation.It will provide support for a large number of numerical simulations in the future,and provide data for researchers to carry out their work.
