摘要
采用综放工作面多角度旋转推进回采技术提高回采率,减少采空区遗煤;采用双抗网联合强化支护防火技术胶结松散破碎围岩、强化围岩强度、提高支护结构承载能力、控制巷道变形,减少漏风;采用立体化压注复合阻化泡沫防灭火技术对支架后和采空区裂隙高处的隐蔽性较强的煤炭自燃隐患进行快速有效治理。
The following technology, including using the technology of muhi -angle revolving mining at the fully -mechanized caving face to raise recovery ratio and reduce the coal loss in goaf; using double anti - network joint strengthening support fire protection technology to cement soft rock, strengthen rock strength and improve the bearing capacity of the supporting structure, control roadway deformation and reduce air leakage;using three -dimensional pressure injection composite retarding foam to put out the coal sponlaneous combustion hidden fire behind the support or at the height of goaf fissure, are used to prevent fire disaster in high gassy exlreinely soft and easy spontaneous combustion coal seam under complex geological conditions and ensure safe and efficient coal production.
