平煤股份七矿戊9-10-16070综采面为大角度旋转多层煤工作面,存在采空区浮煤多、推进速度特慢等多种自然发火因素。通过认真分析工作面的自然发火因素,采用了立体防火技术—架前喷洒阻化剂、架上打钻注MEA防火剂、架后埋管注水、采空区氧化带定点埋管注氮和动点拖管注氮的方法,有效地防止了采空区的自然发火。
Pingdingshan Coal Seamite 9-10-16070 fully mechanized mining face is a large angle rotary multi-layer coal face, there are many goaf floating coal, especially slow to promote a variety of natural fire elements. By careful analysis of the face of the natural elements of the fire, the use of three-dimensional fire-fighting technology - the front of the spray retardant, the frame drilling injection MEA fire agent, after the injection of buried pipe, goaf oxidation zone fixed pipe nitrogen injection and move The method of injecting nitrogen at the point of the trachea effectively prevents the spontaneous combustion of the goaf.
