Shotcrete Support of a Ventilation Shaft in Hard Rock

Abstract:

Ventilation shaft is important for the operation of 18 km long Qinling highway tunnel. The main geological problems encountered in the shaft excavation are high geostress and rockburst. Shotcrete can provide effective support in the rockburst conditions during the excavation of shaft in hard rock. According to the classification of rock mass Q system and engineering experience, the parameters of shotcrete support with bolt and mesh are determined, and the numerical simulation is carried out for stability analysis. Finally the dry mix shotcrete technology is applied for the support.
