Given the dearth of resulting verification ways for the effect of grouting treatment within the water injury space of thick loose layer, a joint uphole-downhole multi-indicator verification methodology is planned to verify the result of grouting treatment on the seam roof by scrutiny parameters like the core observation of grouting layer level, the water level of formation before and once grouting treatment, the output from downhole release borehole, water porosity of stratum, and flowing of slurry injection from downhole borehole. The results show that the grouting treatment has achieved the expected goal and also the operating face has safe recovery conditions. throughout the later workings recovery, no roof dripping development occurred within the well, which is in keeping with the verification conclusion, achieved safe mining at the operating face. The results of the study will give a reference for the verification of the result of suspension treatment within the roof space beneath similar conditions.
