摘要
Abstract
In view of the problem of preventing and controlling the coal spontaneous combustion fire in the goaf area of small coal mine, taking Beidaqu Coal Mine as an example, the characteristics of small coal mine fire area were analyzed, the grouting materials were optimized, and the suitable slurry ratio was determined. A new zonal surface drilling grouting process is adopted to quickly control the small coal mine fire area and eliminate the early hidden danger for the safe working face of lower coal seam. The application effect of this technology in small coal mine goaf area is obvious.关键词
