Apr 01, 2017· At the top of each of the three raises the ore passes through a crusher before it enters the raise proper and thence falls to a pan-feeder, which feeds the belt. The belt system, fed from the three raises, is 4,991 feet long and in nine sections, each driven by a 75-horsepower, 440- volt, A. C. motor. The belt is 7-ply and 30 inches wide.
In-pit crushing and conveying is an alternative transport system which requires a higher initial investment but gives substantial savings in operating costs. An evaluation of the all truck system versus the in-pit crushing and conveying system has been performed by means of a simulation of both transport systems in the same mine model.
In a global environment where energy and labor are becoming increasingly expensive, continuous mining systems such as In-Pit Crushing and Conveying (IPCC) systems have been advanced as offering a real alternative to conventional truck haulage systems.

Apr 27, 2007· Mining operations and haulage systems have progressed in phases exploiting the most current technology. Phase I (1960-1980) haulage system was by trucks only. Phase II (1980 to present) began to exploit the favorable economics of waste haulage by conveyor from a fixed, pit perimeter crusher to the waste dump, with dumping by mobile spreader.
The system allows the continuous transport of ore and waste from the pit to their respective destinations by moving the crushing process near or into the pit with the use of semi-mobile crushers and replacing the majority of the hauling cycle with conveyors. Mine planning for such a system involves different levels of decision-making depending ...
