In this course, we discuss the water and chemical mass balance of a mine site and the many components or facilities that go to make up a mine. There are as many water and chemical mass balances as there are mines. And there are as many mass balances as there are facilities on a mine. In this course we focus on the fundamental theories and methods and illustrate these with examples that are intended to assist and guide in compiling water and chemical mass balances for a mine and its various facilities. This course is one of a series of related courses, others in the series include: Groundwater in Mining Surface Water Management at Mines Objectives Reasons for undertaking a facility or site water balance study may include: evaluating strategies for optimum use of limited water supplies; establishing procedures for limiting site discharge and complying with discharge requirements; estimating the demands on water treatment plants, holding ponds, evaporation ponds, or wetlands.

Mining involves the design, construction, operation, and closure of many geotechnical structures, including: access roads, structural building pads and foundations, ponds, tailings facilities, heap leach pads, and waste rock dumps. Geosynthetics are polymeric materials used extensively in mine geotechnical structures to enhance the performance of such structures. Geosynthetics are used in conjunction with soils and rocks to increase the overall strength of these materials, to control seepage from mine wastes and through soils and rocks, and to separate soils of different gradation and hence to limit piping and potential failure of soil structures. This course introduces you to the types of geosynthetics used in mine structures, to the ways in which geosynthetics may be used to build safe mine structures, and to the many details that will make it possible for you to use geosynthetics at your mine to reduce costs and protect the environment. This course describes many case histories of the successful use of geosynthetics in mining, thereby introducing concepts, ideas, details, and practical applications that you may copy or adapt to the specifics of your mine's needs and facilities.

These impacts need to be quantified before undertaking the project and throughout the mining lifecycle to ensure regulatory compliance, project sustainability, and environmental protection. Common groundwater impacts associated with mining projects may include: aquifer drawdown and/or reduction in groundwater flow due to pumping from groundwater production wells and/or dewatering of open pit/underground workings;loss of groundwater discharge to surface water such as springs, lakes or streams (of particular significance during winter baseflow conditions) due to aquifer drawdown/dewatering related to mining activities;seepage and associated contaminant transport from mine waste units such as waste rock piles, heap leach piles, tailings storage facilities, backfilled and/or flooded pits/underground workings; andoff-site migration of contaminant plumes in groundwater aquifers (originating from mine waste units) and potential discharge of contaminants into the receiving surface water (springs, lakes or streams). The use of numerical groundwater models enables decision makers to study and evaluate potential impacts of large and complex mining projects. Sophisticated models and modelling platforms are, however, no guarantee of good modelling practice. The complexities of groundwater models used for impact assessment may even lead to misuse and/or misinterpretation. This series of two courses on groundwater modelling describes the broader concepts of groundwater modelling related to impact assessment for mining projects. Yet, these guidelines reflect generally accepted best practices in groundwater modelling and as such should be applicable to a wide range of groundwater modelling applications. This groundwater modeling series is based on the British Columbia Groundwater Modelling Guidelines which were commissioned by the British Columbia Ministry of Environment (BC MoE). This course has been modified and condensed to suit the format and (international) audience of an Edumine course. The course comprises ten learning sessions of 30 to 60 minutes each, several case studies, and interactive reviews that confirm achievement of the learning objectives. The total duration of the course is approximately seven hours. Read More

This course discusses the principles and practice of surface water management at mines. It describes best management practices for surface water management at a mine in order to achieve the following objectives. Control surface water in order to prevent pollution of on-site and off-site water resources. Divert excess runoff that may otherwise flood or interfere with mine workings. Limit infiltration to mine waste disposal facilities to control potential pollution of surface water and underground waters resulting from excessive infiltration. Control erosion of the site to limit sediment runoff that may negatively affect receiving waters. Control erosion that may otherwise cause excessive damage to mine closure works. Objectives All mines disturb the surface. All mines change the features of the mine site that affect precipitation runoff, evaporation, streamflow, and erosion. All mines involve grading of the site, diversion of runoff, and placement of wastes that increase or decrease infiltration of surface water to the groundwater. Inevitably at a mine it is necessary to capture and control sediments and other pollutants in surface water, and build and operate the works needed to comply with regulations regarding off-site impact by surface waters running from the mine. Accordingly, this course is intended for all those people at a mine or associated with a mine who may be involved with or responsible for the hydrologic, hydraulic, environmental, civil, and mining engineering works required to manage surface water at a mine.

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.
