受小煤矿侵蚀易燃煤层综放工作面防灭火技术

Fire-fighting Technology in Inflammable Coal Seam Fully-mechanized Caving Face Corroded by Small Coal Mine

对东庞矿北井9204综放面受小煤矿侵蚀导致煤层自燃的防灭火问题进行了分析,结合现场观测结果,判定采空区自燃危险区域,采取了综合防灭火技术方案,有效的防治了采空区煤炭自燃,收到了很好效果。

The paper analyzes the fire prevention problem of inflammable coal seam corroded by small coal mine in 9204 fully mechanized caving face in Dongpang Coal Mine north well. Combined with field observations,the study determines the hazard zone of goaf,and takes comprehensive fire prevention technology project,which effectively prevents spontaneous combustion of coal in goaf and gets very good result.
