摘　　要：为了寻求煤矿瓦斯灾害事故的发生规律,从事故等级、事故类型、事故发生时间和事故发生地域等多角度对2005-2014年发生的煤矿瓦斯事故进行交叉耦合统计分析,统计分析结果表明:较大事故中瓦斯事故次数最多;瓦斯爆炸是瓦斯灾害的主要类型,危害性最大,死亡率高,且容易造成次生灾害;每年的4、5、8、10月和每天的9:00-11:59时段、17:00-18:59时段为瓦斯事故的高发期;贵州、湖南、四川、山西、云南是瓦斯事故预防和监察的重点地区。In order to obtain the occurrence law of coal mine gas accidents, a cross-coupling statistical analysis was conducted for the gas accidents happened during 2005 to 2014 from the angles of accident levels, accident types, time of accidents and location of accidents. The statistical analysis results showed that the most times were larger gas accidents; coal mine gas explosion is the main type of disaster with the greatest danger, high mortality, and likely to cause secondary disasters; the peak of the accidents is in April，May，August and October every year and at daily 9：00 to 11：59, 17：00 to 18：59 period; Guizhou, Hunan，Sichuan，Shanxi，Yunnan are the key provinces to prevent and control gas accidents.
