Sécurité des machines d’extraction commandées par des systèmes programmables électroniques - Fiche technique et Annexe
Avec l'évolution rapide des nouvelles technologies et la recherche de rentabilité des investissements, les systèmes électroniques programmables (PES) ont été implantés progressivement dans toutes les industries. Le secteur minier n'échappe pas à cette tendance et au fil du temps presque toutes les mines du Québec ont équipé leurs machines d'extraction de tels systèmes. Toutefois, l'introduction de ces nouvelles technologies, requises pour l'amélioration de la productivité...
Fault tree analysis and risk mitigation strategies for mine hoists
Mine hoist are an essential part of an underground mine. In addition to extracting the ore from the mine, this machine transports the miners from the surface to the various underground levels of the mine. The two main hazards to which minors in the cage are exposed to are rope severance and loss of control of the hoisting machine. In both cases, the risk is the crashing of the cage at one end of the shaft. Hoisting accident and fatalities are rare but still happen despite the use of safety catches to retain the cage in the event of rope severance. The objective of this article is to improve mine...
ISO 17757:2017 - Earth-moving machinery and mining
Autonomous and semi-autonomous machine system safety This document provides safety requirements for autonomous machines and semi-autonomous machines used in earth-moving and mining operations, and their autonomous or semi-autonomous machine systems (ASAMS). It specifies safety criteria both for the machines and their associated systems and infrastructure, including hardware and software, and provides guidance on safe use in their defined functional environments during the machine and system life cycle. It also defines terms and definitions related to ASAMS. Source: https://www.iso.org/obp/ui/fr...
Secteur minier - Approche intégrée de mesure de contraintes in situ par méthode inverse
La conception sécuritaire des excavations souterraines requises pour l'exploitation minière nécessite une bonne connaissance de l'état des contraintes naturelles du massif rocheux. À ce jour, la seule façon de connaître ces contraintes avec une justesse acceptable consiste à réaliser des mesures in situ. Or, les techniques de mesure de contraintes couramment utilisées dans les mines du Québec se heurtent à des limites importantes sur le plan de la fiabilité et de la précision, ce qui laisse...
Shotcrete Design and Installation Compliance Testing
Early Strength, Load Capacity,Toughness, Adhesion Strength, and Applied Quality The National Institute for Occupational Safety and Health (NIOSH) conducted a research study to document and develop safe practices for the use of shotcrete as ground support in underground mines, particularly in underground metal mines operating in weak host rock. Shotcrete is the generic name for a mixture of cement, sand, fine aggregate, and water that is applied pneumatically and compacted dynamically under high velocity. The objective of this research is to reduce mine worker fatalities and injuries resulting from...
Equipment to improve underground construction safety
An innovative manipulator has been developed to improve safety and productivity in underground construction. Suitable for the mining and building industries, the equipment provides a solution to the significant safety issue of personnel working with suspended loads, especially in confined underground work areas. Local mining contractor Redpath Australia has developed a machine capable of erecting steel beams in underground mines at a much safer and faster rate than the current process using cranes.

A visual warning system to reduce struck-by or pinning accidents involving mobile mining equipment
This paper describes an experiment to examine whether a visual warning system can improve detection of moving machine hazards that could result in struck-by or pinning accidents. Thirty-six participants, twelve each in one of three age groups, participated in the study. A visual warning system capable of providing four different modes of warning was installed on a continuous mining machine that is used to mine coal. The speed of detecting various machine movements was recorded with and without the visual warning system. The average speed of detection for forward and reverse machine movements was...
The internet of things (IOT) and cloud computing (CC) based tailings dam monitoring and pre-alarm system in mines
Tailings disposal is a significant consideration for the mining industry, with the majority of the ore processed in most mining operations ending up as tailings. Several tailings dam failure accidents have occurred during the past few years and mine tailings dam failures, which are disastrous with the serious damage and the loss of lives, are occurring at relatively high rates. To improve the tailings dam safety, a tailings dam monitoring and pre-alarm system (TDMPAS) based on the internet of things (IOT) and cloud computing (CC) is accomplished with the abilities of real-time monitoring of the...
Machines de forage : manuel de sécurité
Longtemps restée dans le domaine de l'empirisme, l'utilisation des engins fait aujourd'hui l'objet de règles nombreuses touchant à la fois au choix, aux vérifications et à la maintenance du matériel, à la formation du personnel, ainsi qu'à la conduite proprement dite. C'est pourquoi ce manuel comprend deux parties : l'une consacrée aux aspects purement réglementaires, l'autre plus spécifiquement dédiée aux règles de bonnes pratiques en matière de conduite d'engins...
MSHA Publishes Proposed Rule to Equip Coal Mine Machines with Protective Technology
On Aug. 31, MSHA published a proposed rule in the Federal Register to require underground coal mines to equip continuous mining machines with proximity detection systems in order to protect miners from becoming crushed, pinned or struck by machinery. http://ehstoday.com/standards/MSHA/msha-proposed-rule-equip-coal-mine-0902/
Report RR831 – Evaluation of tensioned and non-tensioned long tendon reinforcement in UK deep mining conditions
A research programme has been carried out by RMT in support of the revision of Part 2 of the British Standard for strata reinforcement components in coal mines, covering flexible systems for roof reinforcement. This continued work commenced under a previous HSE Project, 'Testing and standards for reinforcement consumables'. http://www.hse.gov.uk/research/rrhtm/rr831.htm
Développement d’une méthode intégrée d’analyse de stabilité des chantiers miniers remblayés
Lorsque la méthode de minage employée nécessite l'utilisation du remblai cimenté en pâte (RCP), il est nécessaire de concevoir un système de remblayage adéquat qui fournira la stabilité structurale requise et la garantie d'un espace sécuritaire à la fois pour les travailleurs et les équipements miniers. http://www.irsst.qc.ca/files/documents/PubIRSST/R-622.pdf
