Résumé Un danger potentiel qui devrait être évalué durant les études d’exploitation par blocs foudroyés est la possibilité d’afflux de boue. Le phénomène des afflux de boue peut avoir des origines très diverses; les résultats sont cependant les mêmes : des blessures, des pertes de vie, des dommages à la propriété, une dilution excessive, des délais de production ou des fermetures de mines. Bien que les afflux de boue soient plus fréquents dans les mines exploitées par blocs foudroyés, toute activité minière qui permet l’accumulation de particules fines et d’eau est sujette à des coulées de boue. Le présent article décrit le processus développé par les auteurs au cours de la dernière décennie pour évaluer le risque d’afflux de boue, surtout dans les mines exploitées par blocs foudroyés et par sousniveaux foudroyés.
Mots clés : Afflux de boue, coulée de boue, déblais saturés, exploitation minière par blocs foudroyés, poussée exercée par la boue, risque

Sommaire: Roof bolts are subjected to axial stresses, shear stresses, or both. Axial and shear stresses were compared between roof bolts machined with two and three slots. Shear stresses perpendicular to and at an angle to the shear planes were evaluated by analyzing a three-slot instrumented roof bolt, performing laboratory tests on two- and three-slot roof bolts, and conducting in-situ test analyses. Three-slot bolts appear to provide a complete bending strain profile, requiring no prior knowledge of...

Sommaire: This paper reviews the evolving Ontario mining regime for mining industry-Aboriginal engagement and its apparent alignment with court decisions, domestic law, emerging international norms, mining industry rules, and mining firm-Aboriginal agreements, drawing on publicly available commentary from government officials, the private sector, and Indigenous communities. This paper provides a preliminary analysis of the potential implications of the new regime, especially for the mining industry and...

Sommaire: This paper studies the characterization and dissolution of a Nigerian pyrolusite ore, reporting the results of ore physicochemical analyses and detailed ore characterization before and after leaching at optimal conditions. Ore dissolution rate increased proportional to acid concentration and temperature, but decreased with ore particle size. In a 4 M H2SO4 solution at 80°C with a particle size of –90+75 μm and moderate agitation, ore dissolution rate reached 78.7%. Unleached residue produced...

Sommaire: The development curve in the extractive sector has become longer, steeper, and riskier due to increased social, legal, and political risks from various stakeholders. Indigenous peoples are a unique stakeholder because their growing legal rights to lands and resources can often determine a project’s outcome. A project will only be successful if it is able to obtain the legal permits, withstand any judicial reviews, and gain and maintain the social license to operate. Stakeholder identification...

Sommaire: Most underground diesel equipment is equipped with diesel oxidization catalysts (DOCs) to reduce carbon monoxide and hydrocarbon emissions. DOCs do not alter nitrogen oxides concentrations but can promote the oxidization of nitric oxide (NO) to the more toxic nitrogen dioxide (NO2). Vale and CanmetMINING have been researching how to reduce worker exposure to diesel emissions by testing mining equipment DOCs. Results indicate a > 77% decrease in carbon monoxide concentration but a 46–315%...

Sommaire: This paper compares Canadian provincial mining safety regulations regarding the use and testing of cage safety catches, including a brief history and evolution. Regulations are similar across provinces, with only slight variations. Currently, the “Ontario-type” safety dog is the most commonly used safety catch in Canada. Performance estimation of the compensation mechanism for different safety-dog shapes and tooth angles show this shape works well and has consistent braking results, but the...
