What are the factors that determining the decision to use trucks or belt conveyors to transport the ore in a new mining. What advantages and disadvantages have each of these options. Thanks in advance for your help, if you can not answer at least I hope someone can recommend some books to read about it.

Continuous (or semi-continuous) mining systems promise to eliminate many of these delays, improve labour productivity and reduce the energy requirements and emissions. Continuous mining systems are not new: originating in Germany, bucket wheel excavators have a long history of operation in lignite mines around the world.

Face Conveyors. Face conveyors are the backbone of any longwall. They act as the guide for the plow or shearer and as an anchor for the advancing roof supports. High-performance ® face conveyors are the most powerful transport systems in underground mining. In service worldwide, face conveyors have achieved haulage rates of 5 000 ...

A surface mining system removes material from a surface mining block that has a substantially vertical and laterally extending mining face. The surface mining system generally includes a miner moveable in a lateral direction along the mining face, a face conveyor extending along the mining face, and conveyor translation devices associated with the face conveyor and operable to move the face ...

Another aspect for the conceptual layout of an underground to surface conveyor system is the aim of limiting underground transfer points. This leads to single flight conveyors with maximum feasible lengths and lifts, and thanks to the recent developments in increased belt …

Traditional mining equipment such as shovel/trucks, draglines, front-end loaders and scrapers are the mainstay of surface mining; however, a new breed of equipment is being increasingly applied. These include hydraulic shovels, bucket wheel excavators, hydraulic bucket wheels, belt conveyors, high angle conveyors and cross-pit conveyors. The various components can be combined to provide a ...
