Course Summary

Introduction

Covers are constructed at mines sites over facilities such as tailings impoundments, heap leach pads, waste rock dumps, sludge ponds, and solid waste disposal units. Generally the cover is constructed as part of the closure and/or reclamation works.

This course is the second in a series of two courses on covers for mine geowaste facilities. In this course, we examine the design and performance assessment of covers, which includes:

  • engineering, scientific, and technical design methods to calculate and quantify just how the cover may perform in regards to stability, infiltration, erosion, and deformation; and
  • the construction, surveillance, and monitoring that will need to be undertaken to put and keep the cover in operation.
The course includes numerous case studies from the author's extensive experience. This course is intended for all who seek to know more about covers for mines and their waste management facilities. There is information in this course for those charged with choosing a cover type, designing and constructing the cover, paying for the cover, and for those regulating and permitting a new cover. There is also information in this course for those who may be evaluating and judging a mine's closure plan, which normally includes one or more covers.

Course Content

Covers for Mine Geowaste Facilities - 2: Design and Performance Analysis consists of 12 viewing sessions of 30–60 minutes each with supporting figures, tables and examples, plus interactive course reviews. Course duration is equivalent to approximately 10 hours of viewing content.

Learning Outcomes

  • List cover design principles and practices.
  • Identify factors that affect cover performance.
  • Describe key elements of the cover construction process.
  • Identify cover surveillance and monitoring best practices.

Recommended Background

  • A degree in engineering, geology, environmental science, or equivalent discipline.
  • Experience in design, construction, or operation of large waste structures in mining.

Jack Caldwell P.E., MS.(Eng.), LLB

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.
