我国煤矿瓦斯事故的发生规律分析

Analysis on the occurrence law of coal mine gas accidents in China

煤矿瓦斯事故一直制约着我国煤炭工业的健康稳定发展,并且其发生频率和强度随着煤矿开采深度的增加明显增大,成为我国煤炭深部开采的主要威胁之一。本文从事故发生的原因、事故的地域分布特点、年份和月份统计规律对瓦斯事故做了进一步的研究和分析。结果表明,在不同种类的瓦斯事故中,瓦斯爆炸事故和煤与瓦斯突出事故最为严重;我国的瓦斯事故也存在明显的南北地域分布的差异;并且年初和年终是瓦斯事故高发的时间段。

Coal mine gas accident has been restricting the healthy and stable development of coal industry in China,and its frequency and intensity increase obviously with the increase of coal mining depth,which has become one of the major threats to the deep coal mining strategy in China.This paper makes further research and analysis of gas accidents from the causes of accidents,the geographical distribution characteristics of the accidents,and the statistical rules of the year and month.The results show that gas explosion accidents and coal and gas outburst are the most serious accidents in different types of gas accidents,and there are obvious differences in the distribution of the north and South regions in China;the number of gas accidents and the number of deaths in the coal mine have been at a high level,and at the beginning of the year and the end of the year are the high incidence of gas accidents interval.
