Product used: Ultrafine Cement K1340

Application scenarios: Treatment of mine fracture zones, reinforcement of surrounding rock in deep wells, and optimization of soft ground treatment.

Project Challenges: The mining area features fractured strata, frequent sudden water inflows, poor permeability of mine backfill and floor rock, slow consolidation, and insufficient stability of mined-out areas and roadways.

Solution: Use ultrafine cement and ultrafine slag powder to treat fractured zones in mine shafts, optimize the structure of soft ground, and enhance the safety and stability of mine shafts; thereby reducing engineering risks and ensuring the smooth progress of the project.

Engineering benefits: Significant improvements in efficiency have led to a reduction in fault leakage, a decrease in the incidence of underground water bursts, and a shorter project duration.
