Far too often, natural resource companies start up new plants without a properly trained operations and maintenance team. The results can be disastrous for both safety and revenue. Obviously the ultimate objective is a plant that operates in a safe and profitable manner. In most cases, the pre-start-up safety training is satisfactory, resulting in few if any accidents during start-up and ongoing operations. However, many plants drop the ball when it comes to properly training operations and maintenance personnel. The payback on a properly executed training program far outweighs the cost. If you are going to budget for high-quality engineering, efficient procurement, and experienced and proven construction management (including commissioning), why leave training open to chance? Performance Associates International (PAI) developed an extensive operations and maintenance training program for Torex Gold’s El Limón-Guajes project in the state of Guerrero, Mexico. In 2015, PAI industry training specialists traveled to the project site to carry out the training for Torex Gold employees in anticipation of plant start-up and gold production. The venture was a “massive success,” according to Nelson Bodnarchuk, Director, Operational Systems. This video tells the story of that success, including generous feedback from the executive officers at Torex recognizing our role in the partnership.
Performance Associates International (PAI) y Torex Gold colaboran para una puesta en marcha exitosa

Con demasiada frecuencia, las compañías de recursos naturales ponen en marcha plantas nuevas sin contar con un equipo de operaciones y mantenimiento debidamente capacitado. El resultado puede ser desastroso tanto en términos de seguridad como de ingresos. Obviamente el objetivo fundamental es una planta que funciona de forma segura y rentable. En la mayoría de los casos, la capacitación sobre seguridad que se da antes del arranque de la planta es satisfactoria, resultando en pocos accidentes (o ninguno) durante la puesta en marcha y operaciones subsecuentes. Sin embargo, muchas plantas son negligentes cuando se trata de la buena capacitación de su personal de operaciones y mantenimiento. Un programa de capacitación bien ejecutado compensa con creces los costos de ejecución del mismo. Si se va a presupuestar una ingeniería de alta calidad, un proceso de adquisición eficiente y una gestión de construcción experimentada y comprobada (incluyendo el comisionamiento), ¿por qué dejar a la suerte la capacitación? Performance Associates International (PAI) desarrolló un programa de capacitación por computadora comprensivo, el cual abarca operaciones y mantenimiento, para su planta de oro El Limón-Guajes en el estado de Guerrero, México. En el 2015, los especialistas de capacitación industrial de PAI viajaron al lugar del proyecto para entrenar a los empleados de Torex Gold en anticipación de la puesta de marcha de la planta y la producción de oro. El emprendimiento fue un “éxito masivo,” según Nelson Bodnarchuk, Director, Sistemas Operacionales. Este video cuenta la historia de ese éxito, incluyendo comentarios generosos de los oficiales ejecutivos de Torex, quienes reconocen nuestro papel en la colaboración.
Why Simulation?
IMMERSIVE TECHNOLOGIES
Simulation based operator training has been successfully applied to a range of diverse industries where high risk and high costs are everyday issues requiring smart solutions. Whether piloting a plane or launching a space shuttle, simulation training has been proven to dramatically reduce risk, cost, unscheduled maintenance, increase trainer effectiveness and efficiency while maximizing productivity. Within the often hazardous mining industry, simulation training has quickly gained recognition as a significant method of increasing site safety and profitability through improved operator skill and knowledge. Simulators provide operators a safe environment to learn and practice their skills while allowing the operator to practice for a range of possible emergency situations. Many of these situations are too dangerous, too difficult or too expensive to test in an actual mine. Operators can also be shown and assessed for the proper operating technique much more quickly and accurately than the traditional in machine approach. Focus on improving operator technique with Immersive Technologies’ simulators has delivered proven results including longer tire life, reduced spot time, reduced brake abuse, improvements in fuel use, reduction in engine overspeeds and more. Simulator training allows operators to be shown and assessed without the need to borrow machines from production. This allows new operators to practice many skills before being placed into a production circuit. Because operators are consistently shown and assessed on the proper operator techniques they have a better understanding and knowledge of the real machine. Following Immersive Technologies release of the world’s first mining dump truck simulator in 1998, their customer results, support network, machine range, global mining footprint, level of realism and OEM endorsements are without equal in the industry. Highlighting the benefits of simulation training, four leading Original Equipment Manufacturers, Caterpillar, Hitachi, Komatsu and Liebherr have chosen to exclusively sign technical information licensing agreements with Immersive Technologies, providing access to proprietary technical information necessary to accurately replicate the operation of their mining equipment. After significant supplier evaluation each major OEM has chosen to exclusively recommend Immersive Technologies' Advanced Equipment Simulators. This unprecedented support and commitment from the OEM's has helped to firmly entrench Immersive Technologies' Simulator technology as the industry leader. This provides customers the comfort of knowing they are investing wisely in a proven and accepted technology that is here to stay. As the world’s largest supplier of mining equipment simulators, Immersive Technologies’ has a customer base that includes many of the world’s leading mining operations, mining contractors, training schools and original equipment manufacturers. Widely recognized as the global industry standard, Immersive Technologies’ has extensive experience in delivering complete training solutions to the mining industry with measurable safety and business improvement outcomes.

MacLean Innovation Report 2018 - Changing the face of the mining industry
MacLean Engineering
Sometimes a turning point can only be seen clearly in hindsight. Such is the case for the mine of the future as we begin 2018, coming out of a 2017 where major mining companies continued to demonstrate capital spending austerity and focus on debt reduction. All the while, there were growing signals that digitalization, electrification and automation were all gaining momentum, even though actual examples of minesite implementations could as of yet, still be counted on one hand. MacLean took the opportunity that industry downturn presented over the past several years to focus intensely on three key product development ventures – first and foremost, the battery electrification of our entire fleet, which will be complete by the end of 2018; second, the successful introduction of face bolting as a feature on our 975 Omnia bolter; and, third, the launch of the latest addition to our utility vehicle product line – the LR3 Boom Lift for heavy load and high reach applications. The past year was one where for the first time we had a fleet of battery electric vehicles working underground, allowing us the ability to validate our performance and total cost of ownership (TCO) models with real-world data, while at the same time continuing to build out our EV offer across the product lines. Looking forward, as we work hard to fully electrify our fleet of ground support, ore flow/secondary reduction, and utility vehicles, we’re keenly aware that electrification is but one step in the ongoing mechanization of underground mining, a transition to the mine of the future that will be increasingly efficient through digitalization and automation that will increase production and reduce costs.
SIL2 / SIL3 certification for its Centurion Guided Radar
Hawk Measurement Systems
Hawk Measurement acquires SIL2 / SIL3 certification for its Centurion Guided Radar to improve reliability in safety instrumented systems in hazardous operations. Hawk Measurement Systems (HAWK), a global leader in measurement solutions, has announced that it has earned Safety Integrity Level rating SIL2 / SIL3 to aid in reducing safety risks in hazardous applications from the International Electrotechnical Commission. This Commission's (IEC) standard IEC 61508 defines SIL using requirements grouped into two broad categories: hardware safety integrity and systematic safety integrity. A device or system must meet the requirements for both categories to achieve a given SIL. Achieving this SIL certification means HAWK’s Centurion Guided Radar measurement systems will provide operators with the added insurance that it will consistently and reliably identify all processes considered hazardous and, if failure was to occur, determine that level of risk. The rating will help evaluate whether this specific technology for the measurement of multiple mediums such as liquids, sludge, powders and granules to a range of 18.5m (60ft) for level meets the selected risk tolerance level. These standards have been widely accepted globally to help define Safety Instrumented Systems and their reliability as a means of assessing and improving their safety. According to Jack Evans, President (Hawk Measurement America), “Risk reduction can be an expensive procedure and operators are looking to reduce that risk to a level as low as reasonably practicable. We take great pride that our Centurion Guided Radar measurement systems have sufficient operating history and that they have a proven track record. HAWK has long been committed to safety and risk reduction and earning SIL2 / SIL3 compliancy will establish a rigorous development process so that our customers can benefit from the advancing technologies that we have to offer.

Training Pays: Actual vs. Projected Start-Up Results
PERFORMANCE ASSOCIATES INTERNATIONAL
Developing a profitable mining venture is no small matter. It requires enormous initial investments in research, construction, and equipment. But a mineral processing plant does not run itself. Even with the best equipment and good ore quality, optimal results are dependent upon keeping the process running smoothly, avoiding process upsets, maintaining process variables in the desired range, and minimizing breakdowns and downtime. A highly trained workforce is an essential element in a successful, and profitable, start-up. The knowledge and abilities of plant operators and maintenance personnel can make or break an operation. Trained operators know what to look for during preoperational and routine inspections, allowing maintenance tasks to be planned and unexpected costly breakdowns avoided. Trained operators know what variables exist at different stages in the process and how to make appropriate adjustments in real time. Trained maintenance personnel are well acquainted with the plant equipment, and maintenance planners can schedule work and maintain a spare parts inventory to minimize downtime. Additionally, new operations that train their workforce just prior to plant commissioning can utilize their operators in the commissioning process. Having been trained and gained field experience through plant commissioning, operators are ready to hit the ground running once feed is introduced. A faster ramp-up means more earnings, more quickly. The cost of developing a proper training program is a small percentage of the overall engineering, procurement, and construction budget but it constitutes a large percentage of the gains realized from a successful start-up and ramp-up to full production. Performance Associates International (PAI) has designed and presented custom training programs for operators and maintenance personnel in metallurgical plants around the world for over 35 years. We are proud to have been part of the successful start-ups at Lundin Mining’s Eagle Mine, Vale’s Voisey’s Bay project, and Torex Gold’s El Limon-Guajes project.

PROCESS CONTROL TRAINING— SIMULATORS ARE ONLY HALF THE STORY
PERFORMANCE ASSOCIATES INTERNATIONAL
With reference to greenfield plant projects, using process simulators similar to the designed plant Human-Machine Interface (HMI) or Distributed Control System (DCS) has become common practice. These simulators represent a “virtual plant” based on process modeling of the circuit chemistry and thermodynamics, and on the physical nature of the plant, including equipment, valves, piping, etc. The virtual plant allows trainees to troubleshoot problems, optimize process variables, react to alarms, etc., all based on the process simulation model. Performance Associates’ experience is that this complex simulator training is valuable, but only after more in-depth training on the process and control logic. To truly optimize a process plant, prior to simulator training, the control room operators must have detailed knowledge of the following:  Process objective of each process system, comprising a group of unit operations.  Process objective of each unit operation.  Process chemistry and the variables affecting it.  Important characteristics of each unit operation, the variables affecting it, and the impact on downstream unit operations.  Plant control loops, interlocks, and alarms.  Safety issues related to the process and control schemes.  Operating procedures for start-up and shutdown under various scenarios, as well as important operator tasks. Additionally, trainees must be intimately familiar with the applicable fundamental scientific concepts, such as pressure, temperature, heat exchangers, electricity, PID control logic, combustion, etc. With this fundamental and plant-specific foundation, the process simulator can be fully exploited for training.
