Résumé J. S. Redpath Limitée, un entrepreneur minier souterrain d’envergure mondiale, a complété plusieurs projets au Canada où des techniques novatrices ont été mises en oeuvre pour raccourcir le cycle de développement. Cet article présente une comparaison entre les méthodes conventionnelles fréquemment utilisées pour le support de terrain, la technique australienne de boulonnage et d’installation de grillage au moyen de jumbos équipés de flèches télescopiques doubles, du béton projeté appliqué durant le cycle de développement et de l’utilisation de deux jumbos et deux boulonneuses côtes-à-côtes dans des galeries de grandes dimensions. Les recommandations et les leçons apprises sont présentées dans le but de fournir au lecteur des attentes réalistes quant aux taux d’avancement du développement dans un environnement minier.
Mots clés : Aménagement à contrat, béton projeté appliqué durant le cycle de développement, boulonneuse à plateforme, boulonneuse jumbo, développement latéral et de la rampe, développement rapide, percement rapide de galeries, technique australienne de boulonnage et d’installation de grillage

Sommaire: The toxicity of arsenic is well known and documented; however, the presence of arsenic in copper electrorefining anodes and electrolytes is critically necessary to produce high-quality cathode. Arsenic as well as antimony and bismuth concentrations vary relative to their concentration in the anode copper received from the smelter. The behaviour and benefits of arsenic in copper electrorefining and the detrimental effects of antimony and bismuth on cathode quality and tankhouse performance are...

Sommaire: In projects involving resource development and plant optimization, the use of in-mine geophysics can deliver considerable benefit. The value proposition lies in using very high resolution downhole measurements to model process-plant outcomes. The calibration procedure used to convert in-situ physical properties into process engineering parameters is illustrated using two iron ore projects. Data correction was related either to orebody structure or mineral formation. The deliverable from this...

Sommaire: Advances in technology provide educators with valuable tools to enhance their teaching and efficiently deliver content to larger audiences. University educators are often encouraged to become more “research intensive” and to increase student enrollment. Faced with these pressures, there is a tendency to use technology to improve teaching efficiencies rather than to enhance existing teaching approaches. Practical learning in applied engineering courses would suffer greatly if hands-on...

Sommaire: Hydraulic fracture (HF) growth through naturally fractured rocks challenges the development of accurate predictive HF models. The authors present laboratory experiments differentiating behaviours associated with orthogonal and oblique intersections between HFs and natural fractures (NFs). HFs were created in sandstone and crystalline (gabbro) rock specimens, impinging orthogonally or obliquely on an unbonded machined frictional interface. Ultrasound monitoring was used to observe the rate of...

Sommaire: Vanadium has been produced from a variety of sources. This metal is known to make aqueous solutions of complex speciation as a function of vanadium concentration and pH. Considering the method of leaching, the impurities in the pregnant leach solution, and the planned vanadium product, different extractants and flowsheets can be applied for solution purification. This paper reviews the purification of vanadium leaching solution using organophosphorus, solvating, and amine extractants. This...

Sommaire: A heptapeptide library displayed on M13 bacteriophages (phages) was screened to identify peptide sequences able to selectively bind to gold, chalcopyrite, sphalerite, pyrite, and silica ores, and to evaluate phage potential as bioflotation reagents. Many peptide sequences were isolated through biopanning and differed from known sequences. Adsorption isotherms were determined and a receptor/ligand interaction model was identified and used to compare affinity of peptide sequences toward ores....
