3.4 Long-Range Mine Planning - Mining Sequence - 1. Technical Overview

Subsequent to the determination of an ultimate pit and ore reserves for metallic and nonmetallic deposits, it is necessary to develop the most profitable long-range mining sequence for the deposit. Long-range planning is a dynamic process because product prices and costs change, additional assay and metallurgical data become available, mining technology and operating prices and requirements change. The three case studies included in this subsection present different techniques for dealing with the objectives of long-range planning. To be able to forecast production, profitability, and capital requirements, it is essential to have a long-range mining plan.
