Abstract: Aiming at the problems of large deformation, high maintenance cost and strong mine pressure appearance of stope roadway under the influence of strong dynamic pressure, a new high-performance inorganic grouting material was developed. Combined with field practice, the pre-grouting reinforcement technology of stope roadway was proposed. The field test showed that the peak value of 23212 roadway roof and floor displacement was 225 mm. Compared with the unreinforced section of 23212 roadway, the deformation was reduced by more than half. The new inorganic grouting material achieved good reinforcement effect, effectively reduced the deformation of the roadway reinforcement area, and was helpful to the safe and efficient production of the mine.
