摘　　要：针对宜昌秭归皮老荒矿区深部矿井煤层瓦斯地质特征,分析了煤巷掘进工作面煤体垮塌的摩擦滑动失稳力学机制,并由此诱导瓦斯大量涌出或煤与瓦斯动力灾害的发生。通过分析此类事故的发生机理及矿区目前的开采现状,针对性地提出了预防措施及改进方法,避免同类事故的再次发生。According to the characteristics of geological and gas in mining area of Pilaohuang,analyzed the friction instability mechanism of coal body collapse in coal roadway drivage face,lead to the occurrence of gas emission or coal and gas outburst. Through the analysis of occurrence mechanism for this kind of accident and present situation of mining area,put forward the prevention measure and improvement method,to avoid similar accident happen again.
