Abstract

Application of teleoperated and automated (or “autonomous”) mobile equipment in underground metal mines represents a promising avenue for overcoming some of the challenges facing the industry. This paper addresses the overall effectiveness of autonomous loading and haulage equipment compared with conventional human-operated machines. Factors affecting availability, utilization, and production rate are explored, and an emphasis is placed on some problems and risks not present in conventional human-operated systems, as well as on the character and criticality of autonomous equipment. The need for a more in-depth analysis of factors affecting overall autonomous equipment effectiveness is stressed; these factors should be taken into consideration at the stage of feasibility studies. The paper concludes with recommendations and directions for future research.


L’utilisation d’équipements mobiles opérés à distance et automatisés (ou « autonomes ») dans les mines de métaux souterraines représente une approche intéressante pour surmonter quelques-uns des défis auxquels l’industrie est confrontée. Le présent article traite de l’efficacité globale des équipements de chargement et de roulement autonomes par rapport aux machines conventionnelles opérées manuellement. Les facteurs touchant la disponibilité, l’utilisation et le taux de production sont examinés et certains problèmes et risques absents des systèmes opérés manuellement, ainsi que de la nature et de la criticité des équipements autonomes, sont mis en évidence. On souligne le besoin d’une analyse plus en profondeur des facteurs touchant l’efficacité globale des équipements autonomes; ces facteurs devraient être pris en compte à l’étape des études de faisabilité. L’article conclut par des recommandations et des orientations pour de futures recherches.

Summary: Testing the effects of bubble size (Db) in a Mo cleaning flotation column at Highland Valley Copper mine indicated that increasing the proportion of small (< 1 mm) bubbles significantly improved column metallurgical response, compared to typical operation. The results were a three- to four-fold Mo recovery increase and a 1 to 2% Mo (absolute) concentrate grade increase. The improved column operation produced a 4% Mo plant recovery increase. This study also showed that modelling the...

Summary: Agnico-Eagle’s LaRonde mine is one of the deepest mines in Canada. Ground conditions in the deeper levels can be very challenging, ranging from hard and brittle to soft and squeezing. As a result, rock mechanics and ground control practices have had to evolve considerably to accommodate progressively deeper mining activities. This paper focuses on the deeper levels of mines and how the difficult ground conditions encountered there have influenced the mining strategy. The first section...

Summary: Rock bolts are the main form of defence against rockfalls in mines. Conditions underground are conducive to corrosion. A perception exists about American coal mines that bolt corrosion is not an issue, especially when bolts are fully grouted. This perception is not necessarily accurate due to the formation of micro-cracks as the resin sets and to subsequent rock movement that breaks the resin column’s continuity. Corrosion should be considered when designing rock bolt support in long-term...

Summary: The scheduling of underground mining activities is a complex task that must simultaneously satisfy a large number of constraints. A schedule optimization tool (SOT) for underground mine planning is described, and its use for investigating strategic decisions is illustrated through a case study. The main components of the SOT include (a) a genetic algorithm that searches for optimal schedules, (b) guidance for the application of heuristic rules, and (c) sliding, which implements just-in-time...

Summary: The influence of using different extraction processes (caustic versus non-caustic) on the thixotropic strength of oil sands fine tailings is examined, as is the influence of adding a coagulant to caustic fine tailings. The thixotropic strength of fine tailings at large void ratios manifests itself as a bonding or gel strength that has been widely noted both in the laboratory and in the field. This gel strength has a significant influence on preventing the initial consolidation or settlement...
