This course explains important steps in the process of open pit mine design. It reviews and discusses the principles of mine planning and design with examples and practices.

Seminar Description

As an introduction, the course begins by explaining different stages of mining projects followed by defining strategic mine planning step. It demonstrates how, by using strategic mine planning techniques, it’s possible to uncover the opportunities and risks in the different stages of mining projects. Open pit mine design techniques are introduced and Lerchs-Grossmann (LG) pit optimization algorithm is explained. Design input parameters and constraints are explained and discussed. The consequence of using different input parameters on the economics of project are explored and discussed. Additional concepts introduced are mill production rate determination, mine production scheduling, and NPV optimization. Most of the topics include case studies and examples of real-life projects. To further develop understanding of mine design concepts, a set of practice examples will be worked through in class, so please bring your laptop to class.

Learning Objectives

This course will help you and your team achieve the following objectives:

  • Introduce the principles of pit optimization and mine planning for those who are involved in the process of making decisions about mining projects;
  • Become familiar with the procedures, terms, conditions, limits, and critical inputs of mine design;
  • Help readers of technical reports and investors better understand and interpret mine design reports;
  • Discuss key mine design terms and concepts (e.g., best case, worst case, base case, cut-off and cut-over grade, strip ratio, metal equivalent, and dilution); and
  • Review and discuss certain mine design techniques (e.g., LG algorithm and production scheduling).

Who should attend?

  • Engineers and geologists involved in mining projects.
  • Managers and directors of exploration and mining companies.
  • Bankers, financial professionals, and investors.
  • Project managers who are not familiar with mine design.
