Is Bigger Still Better? Considerations for Increasing Size of Haulage Equipment
By M. Dotto, T.G. Joseph and M. Curley
Equipment selection is one of the most important decisions made in mine planning. This study analyzes hauler scale impacts on aspects not currently incorporated into conventional mine planning, including expansion of roads to accommodate larger equipment, road layer thickness variation depending on hauler size, and fuel consumption and emissions.
 
The Critical Link Between Loader Productivity, Operator Performance and Mining Costs
By Andrew Jessett, CEO, MineWare
This presentation explores the critical link between loader productivity, operator performance and the overall cost of mining as far as:
  • Performance of material loading assets heavily influence the success of the downstream mining processes;
  • Why inefficiencies on the front end have dramatic repercussions to the overall value stream; and
  • Why the variation in performance between operators on loading equipment will continue to significantly affect the success factor for the whole load-and-haul process.
 
Improving Ingress/Egress Systems on Mobile Equipment
By William L. Porter and Jonisha P. Pollard; National Institute for Occupational Safety and Health, Pittsburgh Mining Research Division
Slips and falls from heavy mobile equipment commonly occuring during the ingress/egress process with root causes being largely unknown. The NIOSH Mining program conducted research to determine injury mechanism and equipment characteristics associated with front end loader ingress/egress injuries. This work included reviewing injuries reported to MSHA and identifying the elements of the system that equipment operators feel create difficulty while getting on or off of their equipment.

Bringing New Life to DC Haul Trucks With an AC Retrofit Package
By Ben Balbach, heavy ındustry and power systems manager, Flanders
With custom designed AC wheel motors built into the DC motor frames and a high performance liquid cooled IGBT drive package that drops into the existing DC drive footprint, old DC haul trucks can now meet or exceed the capability of modern AC haul trucks. An all new, open, flexible, industry-standard control package makes troubleshooting and diagnostic simple. Advanced traction control with a virtual limited slip rear differential greatly improves truck tracking in slippery conditions.
 
Mine Haulage Simulation: 
A Tool Toward Managing Uncertainty 
By Hooman Askari-Nasab, Mohammad Tabesh and Shiv Upadhyay
A mine and extraction simulation operational planning tool with Excel input/output interface and automated reporting has been developed, validated and used as part of the short-range planning of a large-scale oil sands open pit operation in Canada. The simulation tool takes the production schedule as an input and imitates the truck-shovel haulage-systems and its interaction with the extraction plant including crushers and downstream assets. The simulation tool accurately reported the major system’s KPIs at 95% level of statistical confidence within 3% accuracy of the historical dispatch data for the project. This tool gives the planner capability to assess the impact of changing operational scenarios such as stockpiling, different sizes of mixed-fleet trucks, and introduction of new haul-roads into to the mine plan. Normalized results of the project will be presented. 
 
Can “Big Data” Answer the Big Question: 
How Do My Haul Roads Perform?
By Roger Thompson, professor of Mining Engineering, Curtin University, Western Australia School of Mines
Much has been made about the potential of big data to transform mining and how to capture, evaluate and share this information with those decision makers that value the data. While the amount of data available from operations and equipment is increasing, only a fraction of its full value is currently being extracted.
 
Coordinated Operator Training
By Graham Upton, director of business development, Doron Precision Systems
Simulator training reduces accidents and provides efficiency for mine operations. Typically, simulators train one operator at a time for particular operations, whether it be haul truck, shovel operator, or other equipment operator training. A new approach allows operators of two or more vehicles to be fully integrated, immersed, and coordinated within a training scenario. Using multiple simulators, one instructor can train several operators at a time.
 
Session III: Fleet Management
Tuesday, May 9, 2017
 
Innovative Information Mining: Fleet Optimization
By Lia Walker, quality leader, Freeport McMoRan
dvancements in technology have presented an opportunity to gain insights into business and drive efficiencies. Big Data solutions, characterized by large volumes of data that have a wide variety of data types and must be processed at a high velocity, cannot be processed by traditional means. Building on advanced BI and IoT capabilities, the Freeport McMoRan strategy includes developing and implementing a technical solution combined with integration with the business operations to achieve results.
 
How Big is Too Big?
By Craig Griffiths, manager of customer solutions, Volvo Construction Equipment
Mines and quarries around the world are limited by capital available and the deposit’s potential. Quarterly reporting often loses sight of the objective: to sustainably extract the resources available. Operations chasing NPV, IRR while missing the fundamentals of economics can kill a company. Deferring capital expenditure (cash flow) is a fundamentally sound management program for operations. To lose potential cash flow while maintaining a sound bankbook, can be the most economical sound solution for an operation.
 
Analysis of New Truck Fleet and Improvements in the Load Times Supported by Simulation
By Maikol G. Vega, Mining Services, Modular Mining Systems
The use of real time data obtained from a fleet management system allows engineers to include representative input parameters in the simulation process. This paper presents the simulation of a large open pit coal mine, using a haulage simulation software. The study includes the impact analysis of improvement in loading times and the use of double-side loading, the decrease in the variability of the number and time for each pass.
 
Turning Erdenet’s Data Into Dollars
By Job Del Rosario, business solutions manager, Micromine Americas
This presentation is based on a case study involving the Erdenet Mining Corp. (EMC). Finding ways to reduce mining costs and improve efficiency while working complex ore bodies has been a challenge for EMC, a large Asian copper miner. They decided to face challenges by introduction of technology and strengthening employees’ technology skills.
 
Fleet Maintenance Solutions: Air Pre-cleaner Kits Reduce Costs and Increase Performance
By Jill Frederick, Centri product manager, DRM Diversafab
In a climate of volatile commodity prices, mining companies must proactively cut costs without slashing workforce and production. Centri Pre-cleaners recently introduced an air pre-cleaner kit for haul trucks to replace inefficient and exhausted OEM air cleaners. Use of the kits result in decreased air filter usage, reduced fuel consumption, increased production, decreased downtime and reduced recordable incidents.
 
Session IV: Loading Techniques
Wednesday, May 10, 2017
 
Hydraulic Excavator vs. Rope Shovel Performance
By Rodion Andreev, Tim Joseph, John Sammut and Mark Curley
An analysis of dig performance for a hydraulic excavator versus an electric rope shovel of similar size class was performed in terms of the energy required to excavate a unit quantity of the same material from a mining face.  The outcome of the analysis was that the energy per unit excavation quantity of rope shovels and hydraulic excavators are in fact identical. But this does not represent the total picture driving the selection of one excavating tool over another.  The total ‘cost’ of ownership including capital, sustaining capital, operating and maintenance costs, time, availability and utilization must also include the qualitative decisions regarding mining method and the mode of application.
 
Improving Truck-and-Shovel Utilization With a Surge Feeder
By David Pitchford, president, MMD Mineral Sizing (America)
Typical truck and shovel operations have “start/stop” operations; shovel loads a truck and then waits for the next truck to back into a loading position. Mine production is totally dependent, in terms of volume, on the efficiency of that loading method. MMD offers a system that allows the shovel to load continuously; size the rock; feed the surge bunker; load the trucks to max capacity; eliminate trucks having to reverse into the loading position and achieves 20%-35% increase in terms of tons per hour over traditional truck-shovel methods.
 
Shovel-based Fragmentation Analysis of ROM to Improve Blast Planning
By Tom BoBo, director of technical sales and marketing, Split Engineering
This presentation will discuss the importance of providing real time fragmentation analysis as an important metric for determining energy factors for each hole and blast. This study presumes the energy factor is primarily determined by rock type, desired fragmentation distribution, and in-situ fracturing. Data collected over time at Asarco Mission Mine in Arizona, USA supports the evaluation of a shovel based PSD analysis system wherein mine blasting engineers use blast patterns in their short-range planning, therefore; the energy input is changed based on the fragmentation analysis.
 
FREEDOM for Shovel Advancements
By Shawn Rea, excavators manager, Flanders
In 2012, FLANDERS instzled the Freedom adaptive control system called “Optimized Bank Performance,” and the high performance M21 crowd motor—termed Freedom Level 3. A case study was presented at Haulage & Loading 2015 to demonstrate the pre- and post-upgrade performance. FLANDERS has now taken it a step further by installing two high performance M24 hoist motors—this upgraded configuration is termed Freedom Level 7. An updated case study will be presented to outline the performance results of the Freedom Level 7 upgrade.
