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. Topics in include design analyses, performance assessment, cover construction, and surveillance and maintenance. include design analyses, performance assessment, cover construction, and surveillance and maintenance.

In order to understand the impacts of metals on aquatic ecosystems, it is first important to understand the principles of ecology, what an aquatic ecosystem is, and how metals from all stages in the life of a mine are discharged to these ecosystems. The author then examines the properties of metals and how they enter these ecosystems from mining and other human activities. The author presents the properties and uses of specific metals that are mined, or byproducts of mining, in Canada and other countries, and the toxic effects of these metals on fish, other aquatic organisms, and humans. This is followed by an explanation of various toxicity testing methods, their advantages and disadvantages, and how to prevent and control the generation and discharge of acid rock drainage (ARD). The case studies include mine histories, the toxic metals and/or cyanide that are or were generated and discharged to the aquatic environment, actions taken to prevent and control discharge of these pollutants, and the results of the source control actions.

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. This course is one of a series of related courses, some of which are still in development, including Groundwater in Mining Surface Water Management at Mines Mine Water Balance Analysis Authors Jack Caldwell   Duration 14 Hours Access 90 Days Category Geotechnics Level Specialize Version Date January 22, 2016   ​Need to train a team?

This is a concise course on rock engineering for non-engineers in mining. The course addresses rock engineering issues for personnel of mining companies who are not directly involved in mining: people like managers, metallurgists, field geologists... even accountants, secretaries and lawyers. This course has been given to mining companies and mining operations around the world, primarily so that non-engineering personnel can understand what operations personnel need at the mine site level. The goal is to give non-engineering personnel an appreciation of the volume of rock failures and their implications.   A Rock Engineering Primer for Non-Engineers in Mining consists of 7 viewing sessions of 30 - 60 minutes each with supporting figures, tables and examples, plus interactive course reviews. Course duration is equivalent to approximately 3 hours of viewing content.

Underground Mining Methods and Equipment is intended as both a course and a technical reference for an audience of engineers, operators, contractors, consultants, regulators, practising geoscientists and students in the mining sector. The course provides a comprehensive introduction and reference for those who require a solid grounding in selection, design and development of mining methods and equipment. Mining method selection is based upon physical, geological, economical and environmental conditions and constraints. Equipment selection is based upon mining method and related production, performance and cost requirements. Principal course topics include the following. Introductions to underground mining methods, equipment and basic requirements. Mining methods and their application for room and pillar, sublevel stoping, shrinkage stoping, vertical retreat, cut and fill, longwall mining, sublevel caving, block caving, square set mining and other methods. Layout and design of underground mine development and equipment requirements. Equipment and selection for drilling, drifting, production, raising, shaft sinking, loading and hauling. Development and production estimation and costing (note - all costing and estimation information within the course were upgraded to current industry values as of 2012). This is a premium course which has been peer-reviewed by a committee appointed by the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) and the Society for Mining, Metallurgy and Exploration (SME).

Underground Mine Backfill 1 - Introduction is the first in a set of two Underground Mine Backfill courses. This course is intended as an introduction to mine backfill properties, types, uses, mining methods and system layout. Underground Mine Backfill 2 - Slurry, Paste and Rock Fills reviews each backfill type and its preparation, distribution, stope preparation and placement practices as well as relevant safety and quality control issues. A review quiz can be found at the end of each section to evaluate your understanding of the material presented. The objective of the courses is to provide an overview of common underground mine backfill practices and technologies for mine technical personnel. The goals are to: Provide a standard from which operators can understand the basic principles and practices for using underground mine backfill. Provide an understanding of how critical the role of backfill and backfill personnel are for mining. Provide a common foundation for backfill training. Provide a uniform backfill terminology. Provide an understanding of the various stages of backfill systems. Provide an understanding of potential hazards to personnel and equipment safety in order to prevent backfill-related accidents. As many companies have site- and company-specific standards for their unique situations, training for specific operational duties is beyond the scope of this course and is left to mine site-training procedures. This course is not intended to replace existing mine training practices, but to complement them as a common reference. Authors James Archibald David O.
