在对煤矿瓦斯爆炸有关的设备设施进行了有效分类的基础上,对涉及瓦斯积聚和点火源产生的设备设施进行了耦合规律分析,得到了最易引起瓦斯爆炸的设备设施组合。基于统计分析方法找到与设备设施有关事故的直接原因,对设备设施的具体作用类型组合进行了深入分析,并根据事故比例对其进行了降序排列,提出设备设施的安全管控方法建议。
Coupling law is analyzed based on reasonable classification of equipment and facilities related to gas explosion in coal mining,the combination of equipment and facilities is obtained, which is more likely to trigger a gas explosion accident. In order to find out the direct causes, another thorough analysis is done for specific effect classification.Furthermore,descending sort is formed according to the accident proportion. Finally,a security control method is put forward for equipment and facilities.
