摘要
阐述了1W301工作面CO异常情况,分析了工作面CO异常产生的原因。在地面利用测氡法探测采空区高温区域,在井下采用钻探法通过测温和气样标志气体分析判断高温区域。设计采用堵漏风、注浆(胶)、注氮、注液态CO_2等综合防灭火措施对不同位置的高温区域进行火区治理,为制定封闭火区治理方案提供了一种新思路。
CO abnormal situation of 1W301 work face was stated, the cause of CO generation at work face was analyzed. Specifically using radon surveying technique on ground and using drilling detection underground to measure temperature and gas sample. Air leakage blocking, grouting, nitrogen injection, liquid CO2 and other comprehensive fire prevention measurements were designed to control fire area at different positions and provided a path to sealed fire area treatment scheme.
