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. A wide range of cover types have been designed and constructed on mine facilities worldwide, from water covers, through soil covers, geosynthetic covers, and waste rock covers. The specifics of the cover are dictated by the:
- type of waste covered;
- materials available to construct the cover;
- environment of the mine; and
- governing regulations.
This course is the first in a series of two courses on covers for mine geowaste facilities. Covers for Mine Geowaste Facilities - 1: Principles, Practice, and Selection deals with the general principles and practice of covers—what their purpose is, what objectives govern their selection and detailing, and what to consider when choosing a cover for your specific facility. In this course, we examine the:
- objectives of mine closure—the activity that most frequently gives rise to the need for a cover;
- purpose of the cover, and hence the criteria which govern the design, construction, and ultimately the performance of the cover; and
- layers or components of a cover—some to limit infiltration, some to resist erosion, and some to support vegetation.
The course includes numerous case studies from the author's extensive experience. It also includes descriptions of many types of covers that have been used and that could be used at mines.
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.
