摘　　要：针对双合煤矿3_(下)103沿空留巷综采工作面采空区自燃的事实,分析了采空区高温点产生的原因,采取了控制工作面风量、封堵漏风通道、开放式灌注复合发泡剂、封闭式灌注CO_(2)等综合防灭火措施,防灭火效果良好,保证了矿井安全生产。In view of the goaf spontaneous combustion of No.3_(lower)103 fully mechanized working face with gob-side entry retaining in Shuanghe coal mine,the causes of high temperature points in goaf are analyzed,comprehensive fire preventing and extinguishing measures such as controlling the air volume of the working face,plugging the air leakage channel,open injection of compound foaming agent,and closed injection of CO_(2) have been taken with good fire preventing and extinguishing effect.It has been proved that such measures have good fire preventing and extinguishing effects and can guarantee the safety production of the mine.
