摘　　要：矿井火区处理是风险极高的一项工作,火区瓦斯爆炸是近年来导致煤矿重特大事故及矿山救援人员伤亡的主要因素之一。在分析火区瓦斯爆炸特点的基础上,对各类火区瓦斯爆炸的成因进行了深入分析,并应用事故原点理论,重点分析了火区封闭型爆炸原点的形成及转化条件。在此基础上,针对火区瓦斯爆炸风险,就如何安全、快速地处理火区,从通风系统控制、封闭位置选择、封闭顺序确定、施工组织等方面提出了对策措施。The mine fire area processing is a high risk work. Gas explosion happened in fire area is one of the main factors lead to colliery accidents and mining rescue casualties in recent years. In this paper, on the basis of analyzing the characteristics of gas explosion in fire area, a deep analysis on the genesis of gas explosion for all kinds of fire area were made. Especially, gas explosion origin＇ s formation and transformation conditions in closed fire area was analyzed with application of the theory of accident origin. On this basis, discussion was made on how to deal with fire area safely and quickly. Finally, some countermeasures to avoid gas explosion risk were put forward, from the perspective of the ventilation system control, a closed position selection, enclosed order, construction organization.
