煤矿瓦斯爆炸事故共性不安全动作分析

Research on the common unsafe action management of coal mine gas explosion accident

基于研究煤矿瓦斯爆炸事故中共性不安全动作的原因,本文选取了2000年后至今所有公开的201起重特大瓦斯爆炸事故为样本,以事故致因"2-4"模型为理论依据分析了事故原因,并重点对导致事故的一线工人的共性不安全动作进行了研究。结果表明:瓦斯爆炸事故共性不安全动作包括存在无风微风作业、进入禁入区作业等8大类14项。其中,无风微风作业、随意操作局部通风机以及随意开启风门发生频数较多,发生地点集中于掘进工作面和采煤工作面,对应的事故数量占到共性事故总量的63%,发出的共性不安全动作频数占到总频数的64%。

Study of coal mine gas explosion accident common unsafe action, selected after 2000 has all open 201 cases of serious gas explosion accidents as a sample, based on the accident caused theory and ＂2-4＂model to analysis the cause of the accident, and the research was fo- cused on the cause of the accident of frontline staff of common unsafe act. Results show that the gas explosion accidents common unsafe action including wind breeze operations, entre into the forbidden area of operations etc. , including 8 categories and 14 items. Among them, no wind breeze job, random operation local ventilator and optionally opened throttle occurrence frequency are more, place focus on roadway heading face/head-on, coal mining working face, corresponding to the accident number accounted for 63% of the total number of common accidents, a common unsafe move frequency accounted for 64% of the total frequency.
