摘要
通过对自燃厚煤层综放工作面防灭火技术的研究,优化矿井采掘布署、通风系统,研究和应用采空区埋管注浆、三相泡沫、复合浆体喷涂隔风等一系列新技术、新材料和新工艺,在葛泉矿防灭火工作方面取得了明显效果,对于同类条件下的矿井防火,具有一定的指导作用。
Through the study of the spontaneous combustion of thick coal seam fire prevention and extinguishing technology, mining planning and ventilation system were optimized. Goaf pipe grouting, three-phase foam, composite slurry spraying wind insulation and a number of new technologies, new materials and new technology were applied, which made an obvious effect on fire preventing and extinguishing fire in Gequan mine and exerted a certain guiding significance for mine fire under similar conditions.
