Abstract:The slanting lane for cleaning up the main shaft of Huozhou coal electricity group Limited company was planed to pass through the water-bearing stratum of K2 calcareous rock, where the hydrogeological conditions is complicated and its water-bearing stratum belt pressure reaches 5 MPa. To avoid water bursting, this paper introduces the technology of grouting in high-pressure water-bearing stratum, which provides feasible experience for tunneling security. |
