我国近五年瓦斯爆炸事故发生规律与预防措施的探讨

为了研究煤矿事故发生规律及提高其治理效率,本文对2010~2014年度的瓦斯爆炸事故的数据进行了统计,分析了瓦斯爆炸事故地域性及时间性的特点,对引发瓦斯积聚、引爆火源的原因及由瓦斯积聚和引爆火源引起的事故次数做了统计,并且给出多方面的治理措施。统计结果显示:1瓦斯爆炸事故南北存在差异,湖南省、四川省、云南省事故多发;23月份和8月份是事故的高发期,在每月的29日事故发生率较大;3巷道无风或微风是瓦斯积聚的主要原因,电火花、放炮火焰、煤层自燃是火源产生的主要原因。为全面治理煤矿瓦斯提供了支持。

Study on the occurrence regulartiy and preventive measures of gas explosion ac cidents in the past five years in China

In recent years, the coal mine industry has developed rapidly , but the coal mine accidents occur frequently.Gas explosion is the most serious hazard in all the accidents .In order to improve the safety level of coal mine.In this paper , the data of gas explosion accident in 2010~2014 are analyzed.The data from these accidents are analyzed about region and time .The characteristics of regional and time characteristics of gas ex-plosion accident are analyzed .The reasons for the accumulation of gas , the source of the fire and the number of accidents caused by gas accumulation and ignition are analyzed .And according to the analysis of the results gave many aspects of governance measures .Statistical results show:①Gas explosion accident in the north and South differences , Hunan Province , Sichuan Province , Yunnan Province , the accident prone; ②March and August is the high incidence of accidents , the 29th day of per month the accident rate is relatively large ;③Roadway no wind or breeze is the main reason that the gas accumulation , electric spark ,shooting flames , spontaneous combustion of coal seam is main reason for the origin of the fire .Provide support for the compre-hensive management of coal mine gas .
