Abstract:
Haulage systems for future underground mass mining projects are likely to be based on current hoisting and belt conveying technologies with multiple streams and multiple flights in each stream. Hoisting is a batch process. Hoisting systems can incorporate more than one flight in each stream with provisions for buffering and batching in the transfer from one flight to another. These systems are limited in the lift of each flight by the strength and weight properties of the ropes and are limited in production by practical limits on the maximum hoisting speed. Belt conveying, however, is a continuous process. Belt conveyor systems can incorporate more than one flight in each stream with no interruption to the flow in the transfer from one flight to another. These systems are limited in the lift of each flight by the strength and weight properties of the belt and are limited in production by practical limits on the belt speed. This paper presents details of current hoisting and belt conveyor systems in underground mass mining operations, and explores the limits of application of these technologies for the increasing demands of future underground mass mining projects.
