Nevada Gold Mining Operational Efficiencies in the Wake of COVID-19
By Terry Morris, P.Eng., mine manager, Nevada Gold Mines
While the global pandemic has presented the mining industry with a different type of headwind than the norm of cyclical commodity prices, the same fundamental operating strategies have continued to prove effective. Albeit, with some socially distant twists. However, COVID-19 has also done something the industry has been less able to do on its own, it has elevated the importance of workplace health and the management of the “fit for duty” concept to a level nearly equivalent of that of safety. This presentation will highlight several key components for optimizing open-pit mining productivity at a sustainable cost. It will show some parallels between the basic public health measures (mask-wearing, hand washing, social distancing) used to combat the pandemic and the basic mine planning concepts (labor estimation, equipment fleet sizing, truck allocation) that are critical for success. It will also discuss the risk of overreliance on emerging technologies to solve today’s problems. More specifically, how current fashionable trends of autonomy and digital transformation cannot substitute for thoughtful mine planning, proficiency-focused equipment training, and transparent workforce communication. It is the author’s opinion that the best mining enterprises will be those that build (or repair) and then supplement strong foundations of disciplined execution with incremental improvement initiatives over time. Recognizing, of course, that every initiative must be supported by a firm understanding of what exactly the problem is to be solved.
Using Technology to Assess a Potential Fleet Improvement Strategy
By Brian M. Wright, Fort Knox MEM Senior
Developing an enhancement strategy to meet the continuously increasing requirements of a hauling fleet, while at the same time, reducing maintenance costs, is crucial to the success of any mine. Kinross Gold Corp.’s Fort Knox Gold Mine site, the highest producing gold mine in Alaska and located 25 miles northeast of Fairbanks, integrates reliability, availability and maintainability (RAM) to identify and quantify significant causes of operational downtime. By creating a RAM model used as a digital twin of the fleet, the team evaluated the likelihood that the improvement strategy would successfully achieve operational expectations. This work will describe the specific steps for assessing the original condition of the fleet, as well as planning and executing the improvement strategy.
Optimum Economic Assignment of Trucks
By Benton T. Kelly, mining consultant and former mining engineer for Drummond Co.
Most large-scale truck/shovel mines today use a computer-aided dispatch system in the assignment and dispatch of the trucks running at any point in time. This dispatch algorithm dynamically adjusts the shovel and dump assignments in an attempt to optimize the production from the truck fleet. In most of these large-scale mines, there is not a sufficient number of trucks available to ensure the shovels have delay times waiting on trucks. The conventional opinion would be that all loading equipment should be operated in order to maximize production. But when the mine is concerned about the cost of mining a new piece of input data must be considered, that is the cost per BCM of material hauled. This paper discusses the development of a cost matrix from historical operational data from a large truck shovel operation with more than 7,000 loads per day.

Considerations for a Transition to Autonomous Mining
By Drew Larsen, director of business development, ASI Mining
Mining automation is still in its infancy. Many mines are successfully automating their haulage fleets. Some mines are beginning to automate their drilling and blasting operations as well. More mid- and small-tier mines are starting to automate, and mines are expanding automation to different operations. Few mines have a vision for what automation could look like in their mine in five or 10 years. By taking a more comprehensive approach, mines will be better positioned to tap into the power of automation and avoid having to perform hard reboots of their infrastructure to accommodate the next phase.
A Golden Opportunity: Gamification in Open-pit Management
By Phillip Hotzen, Technical Account Manager, MineWare
This presentation describes how one U.S. gold mine used bucket position accuracy and gamification to achieve new loading and haulage efficiencies. While gamification is not new to mining, MineWare technical account manager, Phillip Hotzen believes it has paved the way for greater operator efficiency in open-pit management. Combined with the latest industry advances in machine guidance technology, gamification and bucket level precision of a machine and material model interactions have opened the door to new levels of productivity and mining process efficiencies. In this practical, case study presentation, Hotzen will share real world outcomes that demonstrate the critical link between the optimization of loading and hauling processes, and the efficiency of downstream operations.
Full-scale Numerical Simulations to Optimize Rope Shovel Loading Performance
By Andreas Svanberg, Industrial Ph.D. Candidate, Boliden
In this work, a full-scale simulation model for the loading process of a mining rope shovel is developed and tested. The work has been carried out in Boliden’s open-pit copper mine Aitik, located in northern Sweden, with the objective to increase productivity and reduce costs related to wear and damage. A simulation model is calibrated and validated with real in-situ experiments. The correlation between reality and simulations shows excellent agreement. Results from this work are of high interest in creating a better understanding of the bucket filling process and is critical in optimization-related questions.

Safety & Training, Tuesday morning (March 16, 2020)
Potential New MSHA Regulations for Surface Mobile Equipment and Powered Haulage Equipment
By Mark E. Heath, Spilman, Thomas & Battle PLLC, Charleston WV (co-chair firm MSHA and OSHA Practice Groups)
For the last few years, MSHA has been considering new regulations on safety programs and cameras for powered haulage. MSHA now appears likely to enact a regulatory change later this year on safety programs and equipment. This topic would look at the development of the issues in the last 10 years, serious incidents over the years and potential new regulatory requirements.
GMG & ISO Coming Soon Surface Mining Operational Safety Focused Standards

Personnel Safety Around Fixed Equipment
By Mike Walling, general manager of safety electronics, Strata Worldwide
Working around mobile mining machinery is a well-known risk to personnel safety. Proximity detection systems have been developed to address these risks and increase worker safety. Strata Worldwide now recognizes a significant safety concern involving personnel working alongside conveyors and conveyor bridges. Strata’s HazardAvert has been adapted to target these safety issues and has been placed around the high-risk components of this equipment to help mitigate these hazards.
Innovation in Mine Training Achieves Supervisor Proficiency at Faster Rates
By Richard Beesley, professional services manager, Immersive Technologies
Traditional training methods are inefficient requiring long durations of time and often leave new field supervisors with gaps in their knowledge. Infield supervisor training has blind spots as the trainee is kept at a safe distance and can only see what is happening from that one point of view. New technologies are advancing the way supervisors learn. They can be immersed in a virtual environment where they actively participate in their learning and can experience in a matter of hours what could take months with traditional training. Application of these technologies have proven results with greater efficiency and training retention.
Optimization Strategies, Tuesday afternoon (March 16, 2021)
An Integrated Approach to ROM Fragmentation, FMS and Impact of Primary Crusher Feed
By Tom BoBo, director of business development, Split Engineering (Hexagon)
Run of Mine (ROM) fragmentation feeding the comminution circuit is a fundamental mining process. However, oversized rocks feeding the plant have a great impact on production. A typical mine can see anywhere from 1 to 5 hours a day of lost crusher production, due to oversize from the ROM. Using a real-time ShovelCam or TruckCam system integrated into the FMS (Fleet Management System) to reroute trucks that have oversize, can have a multimillion-dollar impact on the bottom line and help avert the potential loss in revenue.
Benefits of using On-Board Scales on Underground and Above Ground Mining Vehicles
By Bill Zimmerman, R&D Design Engineer, VPG Onboard Weighing (Vulcan On-board Scales)
Weight information helps to maximize payload efficiency while avoiding overweight conditions. Management can use the weight information to determine loading efficiency of the vehicle, carry back weight and monitor unused truck capacity. Overload information can be used to track truck frame fatigue and to create vehicle service strategies. This presentation includes case studies from nickel mines in New Caledonia and lead mines in Missouri.
Emerging Technology in Non-traditional Surface Mining Loaders

Optimizing Payload Management
By Modular Mining
Automating payload management is a highly effective practice to help mines accomplish their profitability goals. Instantaneous, real-time visibility into the amount of material being loaded and moved helps increase fleet efficiency, productivity and utilization. But miners can extract even more value from their payload technology if they can integrate that technology with other systems. This presentation will demonstrate how miners can optimize their payload management practices by integrating three different technologies from the OEM and OTM: a robust FMS, real-time shovel payload feedback, and on-truck payload overload protection. The presenter will show how this integration can tighten payload distribution in trucks, allowing miners to target a more aggressive truck payload and optimize shovel productivity.
