The mine main shaft of Xinhu Mine was 1 009.5 m in depth and 6 m in net diameter and was constructed with a shaft drilling and grouting parallel operation. AS borehole surface ground pre-grouting would not occupy the mine shaft construction period. The S borehole surface ground layout could avoid the surface facilities of the mine shaft construction. When the base rock section of the mine shaft was at the designed grouting scope ,the base rock section grouting was conducted. Agrout liquid of 27 007.5 m3 was grouted in the mine shaft ,a residual water inflow was 3.5 m3 /h and a dry mine shaft sinking was realized.
