Potential Applications of Portable Underground Hardrock Crushers

• Description:
  In many underground mining operations the highest cost is the loading and haulage of run-of-mine ore. Ore hauling costs can be reduced significantly with the use of belt conveyors, a common practice in coal and other soft mineral mines, if oversize ore can be eliminated prior to conveying, hence the demand for crushers close to production areas. Portable feeder-breakers are used extensively in conveyorized coal mines, but no such equipment is available to extend the benefits of belt conveyor haulage into hard rock mines of low-to-medium headroom. A hardrock crusher that could be easily moved would permit the use of lower cost haulage means, and would improve the safety and productivity of all elements in the underground ore hauling system. This report describes a study to determine the optimum design parameters, and provide a concept, for the design of a low profile, hardrock, portable underground crusher to ensure that future development will lead to maximum utilization by the industry.
