The primary access shaft for the West Reef is the Central Shaft located in the town of Prestea and the secondary shaft
is the Bondaye Shaft, 5 kilometers to the south.
The secondary shaft
does not have a conical group any more, which eliminated a large portion of clearances.
Both liner and disc form an integrated part of the primary and secondary shaft
sealing, and are moulded and machined for low torque, less stress and deformation during operation, and elimination of tearing and bunching.
In this purpose, will consider the elements geometriey of the hydrodynamic torque converter as a constant and as variable the rotational speed at the primary shaft and the load to the secondary shaft
The situation is created by insufficient lubrication of the transmission's secondary shaft
second gear that can occur under certain driving conditions.
for microtunnelling inspection: 8 nA
The main silver vein is traceable on surface for 1100 metres (3600 ft) with both ends of the vein each having an 80 metre (252ft) deep shaft with secondary shafts
existing in between.
