Pit Optimization – How I View It

Pit Optimization – How I View It. One of the first steps in open pit mine design is the pit optimization analysis. Pit optimization is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters include the metal prices, process recoveries, and operating costs.

Estimation of the potential production rate ...

In 1978, H.M. Wells published the paper "Optimization of mining engineering design in mineral valuation", which proposed maximizing the present value ratio (PVR) in order to find the optimal production rate. PVR is the ratio of PVOUT (the present value of positive cash flows) to PVIN (the present value of negative cash flows).

Analysis and Optimization of Entry Stability in ...

As the width of the entry wall decreased, the integrated vertical stress, induced by two adjacent mining panels, coupled with each other and experienced an increase on the entry wall, which inevitably weakened the stability of the entry. Therefore, mining with coal pillars always involves a tradeoff between economy and safety.
