WWW.HAULAGEANDLOADING.COM REGISTER ONLINE TODAY Conference Program: Using Technology to Manage Operations Eff ectively Session III: Fleet Management Innovative Information Mining: Fleet Optimization By Lia Walker, Quality Leader, Freeport McMoRan Advancements in technology have presented an opportunity to gain insights into business and drive effi ciencies. 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 strat- egy includes developing and implementing a technical solution combined with integration with the business operations to achieve results. How Big is Too Big? By Craig Griffi ths, Manager 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 fl ow) is a fundamentally sound management program for operations. To lose potential cash fl ow 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 fl eet management system allows engineers to include representative input parameters in the simu- lation 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 load- ing, 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 effi ciency 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 pro- actively cut costs without slashing workforce and production. Centri Pre-cleaners recently introduced an air pre-cleaner kit for haul trucks to replace ineffi cient and exhausted OEM air cleaners. Use of the kits result in decreased air fi lter usage, reduced fuel consumption, increased production, decreased downtime and reduced recordable incidents. Session IV: Loading Techniques 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 selec- tion 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 effi ciency 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 & 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 analy- sis 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 Shovels Advancements By Shawn Rea, Excavators Manager, Flanders In 2012, FLANDERS installed 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 confi guration is termed Freedom Level 7. An updated case study will be presented to outline the performance results of the Freedom Level 7 upgrade. Conference Schedule Subject to Change
