block caving and primary crushing

Geotechnical factors

A schematic of block caving is shown in Figure 3. This method is distinct from all others discussed thus far as the primary fragmentation is achieved by natural mechanical processes. Block caving is a mass mining method, capable of high, sustained production rates at relatively low cost per tonne.

Magma from the ashes.

Oct 01, 1992 · Block caving at San Manuel produces highly fractured ore which requires no crushing underground. Four 1,100 t/h gyratory crushers on surface, adjacent to the production shafts, prepare the ore for the 11 km rail haul to the concentrator. There it is further reduced in one of 11 cone crushers.

Numerical modeling of influence parameters ...

Introduction. Block caving is a method that is completely based on the principles of caving. This method is based on the assumption that ore fractures and breaks by itself, due to the presence of internal stresses and forces caused by the weight of the ore body and also the downward movement of the broken rocks. 1 The deposit is divided into large blocks, usually square in .
