Course Summary

Introduction

In this course, we focus on groundwater theory and practice applicable to mines and the specifics of open pits, shafts, underground mine workings, heap leach pads, waste rock dumps, and tailings impoundments. We discuss, for each of these facilities, the principles of groundwater and facility design & operation that apply and must be implemented to control and protect groundwater and surface water.

Objectives

This is the aim, objective, and central message of this course: understand the physical world that is your mine; understand the theoretical principles that govern processes at your mine; do every calculation you can to elucidate and illuminate the interaction of your mine and its environment; and finally act as a professional ... act responsibly on the basis of informed judgment.

Accordingly, in this course, we examine the basic principles of groundwater flow in soils and rocks; we discuss the principles of groundwater flow to typical mine facilities, including open pits, underground mine workings, and the waste disposal facilities such as the tailings impoundment, the waste rock dump, and the heap leach pad; we evaluate how groundwater flow may influence the cost and safety of such mine workings; and we consider practical engineering methods to control groundwater flow to make mining safer, more cost-effective, and more environmentally friendly.

Content

The course comprises 18 viewing sessions, each of 30 - 60 minutes duration, plus supporting figures, tables, worked examples and references, and interactive reviews that confirm your achievement of the learning objectives. The total duration of the course is approximately 14 hours.

Learning Outcomes

  • Identify the basic principles of groundwater flow in soils and rocks and apply these to typical mine facilities.
  • Apply the principles of groundwater flow to open pits, underground mine workings, tailings impoundments, waste rock dumps, and heap leach pads.
  • Evaluate practical engineering methods to control groundwater flow to make mining safer, more cost-effective, and more environmentally friendly.

Recommended Background

  • A basic knowledge and understanding of mathematics, physics, and chemistry.
  • A basic understanding of the fundamentals of mining and the nature, purpose, and function of mine facilities.
  • Perspective and understanding of environmental, engineering, and technical procedures and practice.
  • A desire to know more and a willingness to apply interest and curiosity.

Jack Caldwell, P.Eng, has a B.Sc. in Civil Engineering, an M.Sc. (Eng.) in Geotechnical Engineering and a post-graduate law degree. He has over 35 years engineering experience on mining, civil, geotechnical and site remediation projects. He has worked on numerous projects throughout southern Africa, Europe, Latin America, Canada, and the United States. His project experience includes:

- mines and waste disposal facilities - design, construction supervision and reclamation of tailings impoundments, mine rock dumps, heap leach pads, landfills and radioactive waste disposal units;

- hazardous and radioactive waste site remediation - senior management and technical consultant

- landfills - design, construction, operation and closure with special focus on liners, covers, and soil reinforcement.

In addition, Mr. Caldwell has been the lead specialist for various geotechnical and civil engineering projects in Southern California. Mr. Caldwell has written many engineering reports, proposals, and technical papers. He is the lead author of the book, Principles and Practice of Waste Encapsulation, on the design of waste disposal facilities for radioactive and hazardous wastes.
