Equipment selection

Preliminary Selection Considerations. Equipment selection for a hard-rock mine typically begins with or soon after the planning parameters of the stoping operation is completed; therefore, equipment used for stoping should be suitably sized for the stope dimensions and the characteristics of the orebody. However, it is also impractical to commence mine planning and scheduling without a working.
