| Abstract: | Based on analyzing the roadway sand properties in Xiayukou mine, through the indoor test on silicic acid gel grouting material to analyze the feasibility of fine sand. And the effect of slurry grouting quantity, proportion, age as well as the accelerator of fine sand on reinforcement effect is elaborated. Regularity of the grouting amount, size, proportion of accelerator and age strengthening effect on the fine sand was determined. The results show, through the fine sand tunnel grouting reinforcement scheme is reasonable and feasible. |
