Abstract：According to the water quality analysis and hydraulic pressure analysis for Linnancang Mine, the source of water inrush in the -650 level was 5# coal seam roof aquifer ( V ) . GIS and AHP technology was applied to draw the thematic map of water flowing fracture zone height in 12# coal seam roof and the caving safety zoning map. Water richness of water-filled aquifer in coal seam roof was evaluated and zoned, and the water inrush conditions were comprehensively evaluated. The results showed that, the danger zone of water inrush is mainly concentrated in the northeast and the northwest, and the risk gradually decreased from the south to the north.
