Calibration of a mixing model for sublevel cavingKnow More

Sublevel caving SLC is an underground mass mining method where the orebody is divided into a regular network of tunnels The ore is extracted by level working downwards through the orebody The caved waste from the overlying rock mass fills the void created by ore extraction generating a dynamic mixing situation between the broken ore and the waste dilution from upper levels The dynamic...
