kavern uses Commercial Mathematics to improve mining efficiency maximising throughput in underground and open-pit mines with optimised equipment scheduling Plan Execute Plan shifts ahead of time and respond to changes while executing.
Mass mining methods are credited with low operating costs due to such advantages as high production capacity and efficiency. Open pit mining is widely used in large orebodies at shallow depth or that outcrop on surface. 1 The depth of open pit mines is restricted by the stripping ratio. When the open pit mine reaches its designed ultimate depth .
