高地温综放工作面撤架期间的防灭火技术研究

Study on the technology of fire prevention and extinguishment in high temperature fully mechanized caving face

以唐口煤矿6305综放工作面为工程背景,分析了工作面撤架期间的自然发火原因,采取了调整通风系统、灌注二氧化碳、封堵进回风隅角、设置气体及温度传感器等综合防灭火措施,取得了良好效果,并为6306、3309综放工作面自然发火防治提供了技术支持。该成果对综放工作面撤架期间防灭火工作具有较好的指导作用。

Taking Tangkou Coal Mine 6305 fully mechanized caving face as the engineering background, analyzed the cause of spontaneous combustion during working face support withdrawal, took the comprehensive fire prevention measures ,such adjusting the ventilation system, pouring carbon dioxide, plugging intake and return air corner, setting up for gas and temperature sensors, and achieved good results, which provides technical support for prevention and control of spontaneous combustion of the 6306, 3309 the working face, The results of this paper can be used as a guide for the fire prevention and control work in the fully mechanized caving face.
