摘要
矿井火灾为煤矿"五大"灾害之一,通过描述15101综放首采工作面采空区的瓦斯综合治理现状,制定了综合防灭火方案,加强采空区顶板管理,采取了在上下隅角悬顶时砌筑袋墙,在回风上隅角加设风水射流器,工作面埋设干冰降温等相应的防灭火措施,为类似煤矿采空区的瓦斯综合治理提供了借鉴.
Fire is one of the“Big Disasters”in coal mines.Based on the current comprehensive gas control in the goaf of the first mining face of the No.15101 fully mechanized working face,the paper proposed a comprehensive fire prevention plan,including strengthening roof management in the goaf,building walls when suspending roofs at upper and lower corners,adding water and air jet in the upper corners,and burying dry ice to cool,which could provide a reference for the comprehensive fire control in the goaf in other coal mines.
