ABSTRACT

Grouting technology serves as a prevalent method for preventing and controlling mine water damage, with directional grouting emerging as a notable approach in recent years. This study introduces an optimized whole-area fine grouting method aimed at enhancing the layout of directional drilling, reducing grouting blind zones, and cutting costs. Theoretical foundations and simulation analyses validate this method. A simplified mathematical model demonstrates that positioning branch holes at a 60° angle to the main holes optimizes cost-effectiveness while eliminating grouting blind zones. Furthermore, numerical simulations of slurry diffusion in 45°, 60°, and 75° configurations using COMSOL software reveal that the 60° arrangement significantly reduces grouting time for a given reformed area.
