Both ore bodies will be accessed through two vertical shafts, blind sunk to a depth of 1 065 m. The service shaft has a finished internal diameter of 7 m and will provide all the services to the underground workings, while the production shaft, also with a finished internal diameter of 7 m, will be fitted with two rock winders, each having two ...
The vertical alignment can be done by Plumb bob Optical collimator Laser A heavy plumb bob (5 to 10 kg) is suspended on either a wire of heavy twine. Oscillations of the bob can be controlled by suspending it in a pot with high viscosity oil. The bob is suspended from a removable bracket attached to the surface side of the shaft.

The principal means of access to an underground ore body is a vertical opening called a shaft. The shaft is excavated, or sunk, from the surface downward to a depth somewhat below the deepest planned mining horizon. At regular intervals along the shaft, horizontal openings called drifts are driven toward the ore body.

bored tunnel. The main collider ring will be connected to the surface by clusters of vertical shafts which provide access for personnel, utilities, ventilation and equipment including the 17m long magnet cryostats. These shafts are located on the Service Areas at intervals of ap-proximately 4.4km around the ring.
In an underground transport system, for instance, the tunnels are driven to connect inclined or vertical shafts (points of surface entry to the transport system) whose relative locations are established by surface surveys. Thus the underground control networks must be connected and orientated into the same coordinate system as the surface networks.
