Abstract：The backfilling and reinforcement of the mine shaft boring liner should have the filling grout and the conventional filling method would be cement fillings.But the cement grout filling would have high cement consumption and a high cost.A mine shaft coring sinking method was applied to the mine central ventilation shaft of Xinhu Mine.The second section of the mine shaft was backfilled with the cement grout and the cement and sand grout.The cement and sand grout was applied to replace the partical cement grout and the expected effect was reached.The paper briefly introduced the horizontal pumping test of the cement and sand grout at the surface ground,the comparison tests of the cement grout performances and the backfilling condition of the cement and sand grout.
