ABSTRACT
This paper reviews the use and application of highly mobile track mounted crushing units and continuous belt conveyor systems to handle the waste muck in the hostile and restricted space of tunnelling and cavern developments, as a better and more cost effective alternative to the conventional use of haul trucks. By using this approach, it can be demonstrated that savings in mucking costs of up to 35% are possible. Particular reference is made also to the important additional benefits related to operational safety, health and environmental conditions in tunnels.
