Underground Mine Environment 2: Environmental Contaminants is the second course in the Underground Mine Environment series of courses based on material developed by Mining Education Australia, a national joint venture initiative between the University of New South Wales, the University of Queensland, and Curtin University of Technology. The course gets into the details of mine gases, detection systems and data interpretation, as well as hazards that have a direct impact on mine ventilation, such as dust, mine fires, and radioactivity.
Part 1 provides an overview of mine gases encountered in mines (i.e. their properties, sources, and physiological effects), dealing with flammable and explosive gases, and gas laws.
Part 2 covers gas detection systems used in underground coal and metalliferous mines, methods of interpreting data and reporting, and issues affecting the installation and operation of gas monitoring systems.
Part 3 deals with airborne and explosible dust—properties and behaviour of dust in the atmosphere, physiological effects, measuring concentrations, sources, control, and dusts that may form explosive mixtures.
Part 4 deals with underground mine fires—the causes of fires and explosions, types of fires and their detection, effects on the ventilation system, firefighting and control, and evacuation and refuge.
Part 5 provides a brief summary of radioactive theory required to understand the behaviour and control of radon in mine ventilation circuits, and then describes how to design ventilation circuits that control exposure of the workforce to radon progeny in underground mines.
Underground Mine Environment 2: Environmental Contaminants is structured in five parts and a total of 32 viewing sessions of approximately 30–60 minutes each, plus course reviews, appendices and extensive references. Current course duration is equivalent to approximately 25 hours of viewing content.
