The purpose of this course is to provide mine staff the tools required to effectively gather geotechnical data for rock mass classification and rock mechanics design calculations. The majority of rock falls in mine operations are structurally controlled. Design is largely controlled by existing structure. It is critical that site characterization be performed so as to identify the structural factors that would affect rock slope angles, drill and blast design, support requirements, resultant dilution and span design, etc. A good understanding of rock mass structure forms the basis of rock mass classification which is used in the majority of rock mechanics design methods. Upon completion of the course students are able to gather geotechnical data, either from rock cuts, drifts or core, and process the information for subsequent analysis. The focus of the course is towards gathering information for purposes of analysis and design. The goal is to use effective mapping techniques to obtain data that can be used as input for any of the established rock classification systems. All of the commonly used classification values such as Barton's Q and Q' systems, Bieniawski's RMR, Laubscher's MRMR and Hoek's GSI systems are covered.

The scale and nature of mining projects may result in impacts to the receiving environment, including groundwater resources. 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; and off-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 course 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 course 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.
