煤矿瓦斯爆炸灾害事故的MORT分析

MORT analysis of coal mine gas explosion casualty

煤矿经常发生事故,且瓦斯爆炸事故后果严重.造成瓦斯爆炸的原因很多,运用管理疏忽与危险树(MORT)分析方法,对瓦斯爆炸造成煤矿灾害事故的管理与技术进行分析,并建立MORT模型,为煤矿企业预防安全事故、提高安全管理水平提供了更经济有效的方法和新的思路.结果表明:煤矿瓦斯爆炸发生的可能性与领导重视程度有很大程度的相关;制定各种规章制度;提高全员对危险因素的认识;改善巷道的设计、瓦斯浓度的监测、通风系统的设计与布置;控制火源等方法都能有效的防止瓦斯爆炸事故的发生.

It is well known that coal mine accidents occur frequently, and the gas explosion consequence is serious. There are a lot of reasons to cause the gas explosion. Using Management Oversight and Risk Tree to analyze the causes of coal mine gas explosion caused by the management of disasters and accidents, this paper establishes the MORT mode, in order to prevent accidents in coal mining disasters and provide a more economical and effective methods and new ideas for improving the safety management level. Results show that there is much correlation between the gas explosion and the emphasis of the leadership. Following methods, i.e. formulating rules and regulations, improving the whole members＇ awareness of risk factors, improving the design of roadway, the gas concentration monitoring, and the design and the arrangement of ventilation system, and controlling combustion source, can effectively prevent the gas explosion accidents.
