Sommaire: The Athabasca oil sands mineable resource is located in northeastern Alberta, Canada. In oil sands mining, the ore zone is regulated to have a minimum mining thickness of 3 m and a cutoff grade of 7 wt.%. The current algorithm that is widely used to flag ore zones and waste zones tends to overestimate oil reserves and causes low-grade ore to be processed. This paper presents the development of a more complex algorithm that is more representative of the actual oil found during operations and...

Sommaire: This paper concerns the identification of weak zones in the structure of a rock mass endangered by outbursts of gases and rocks at approximately 1,200 m depth in the Rudna copper ore mine, Poland. Geophysical recognition with the aid of seismic tomography and borehole ground-penetrating radar was applied, along with geological engineering tests. Results showed a very strong correlation between the location of the zone containing gases and water, the anomalous S-wave velocity, the field of the...

Sommaire: Geotechnical monitoring is a key element of the successful management of a block cave mine. The interrelationships between production and various monitoring datasets are often not realized due to a lack of data integration and appropriate 3D visualization. Timely delivery of information to ensure best cave management practices is only possible with an integrated cave management system. At Rio Tinto, a state-of-the-art cave management system (CaveCAD) has been designed and developed in...

Sommaire: Mineral resource development activities impact the health and well-being of many people, including workers, their families, and the surrounding communities. With industry growth predominantly in rural and remote areas, companies often implement long distance commuting (LDC) programs to staff sites with limited local populations in Australia. Results are presented from a survey of Australian resource industry LDC workers regarding variable nonresident accommodation arrangements and individual...

Sommaire: Autonomous robots are useful for 3D underground mine mapping to avoid human exposure to hazardous spaces. To prepare a precise mine map, a self-navigating robot must navigate an arduous path, avoiding obstacles and sensing the environment. A prototype laboratory-scale robot was built and evaluated through a mock-up in a test mine gallery. It was outfitted with a 2D laser scanner, a stereo camera for obstacle avoidance, and a high-precision, laser-based imaging and digitizing system for...

Sommaire: High levels of geological heterogeneity occurring over relatively short distances pose a challenge to the unconventional open-pit techniques used in oil sands mining. There is strong motivation to mine selectively and minimize dilution and loss; however, the large equipment and high mining rate used to meet production targets tend to reduce selectivity. A numerical model is developed to account for geological complexity, mining equipment, regulatory criteria, and other operational parameters....

Sommaire: Real-time wear and corrosion measurement provides crucial information in determining an optimal schedule for corrective maintenance and is a powerful tool to maximize equipment availability and reliability. This paper presents integrated ultrasonic transducers (IUTs) that—when incorporated into structures to accurately measure the remaining thickness—can determine wear or corrosion losses. Transducers have a small footprint, perform comparable to other commercial ultrasonic transducers, and...

Sommaire: The Canada Mining Innovation Council (CMIC) Exploration Innovation Consortium developed a 10-year business case for developing new discovery criteria, exploration techniques, and better data management and analysis to improve exploration success in deep, remote, and covered terrains. Within this context, the CMIC devised a five-year project proposal to create improved multiparameter exploration tools to detect ore systems and more efficient vectoring toward high-grade mineralized cores. The...
