FLEET MANAGEMENT Critical to customer success is all assets from a variety of vendors, talking to each other. We promote data engines to take full advantage of interoperability, from planning, to operations, to market. Mines should not let anyone sell them on a complete, expensive system with decades of implementation. Hexagon believes in a fully scalable IoT platform that begins with making a mine’s existing investment smarter, scaling only as fast as its budget allows and driven by proving each phase pays for itself before embarking on the next milestone in an IoT roadmap that the mine defines.” VIST and the true digital mine VIST Group FMS customers include Severstal, Evraz, SUEK, EuroChem, Metinvest, OCP, NLMK, Polymetal, Polyus and ArcelorMittal. But for the past five years a major focus has been investing in the future technologies in mining, such as autonomous dump trucks, autonomous drilling rigs and predictive analytics for different applications in mining. Dmitry Klebanov, VIST Group Business Development Director believes the worlds of dispatch, autonomy and process analytics are rapidly converging. “The main difference of our modern approach of providing solutions to the mining industry is that we provide a true digital mine, not only a module with health monitoring or optimisation of the fleet. Some vendors are well known for offerings that highlight health monitoring and dispatch, others focus on industrial safety and still others predictive analytics and robotics…but there are gaps between all these functions, since vendors do not generally provide change management and are not process consultants. In the near future, consulting companies, such as McKinsey, Accenture and BCG will start implementing technologies, and will be able to compete with the usual vendors of IT technologies in mining, because they have the competence in organisational changes that are necessary for a modern digital mine.” The VIST Intelligent Mine offers unmanned mining operations with autonomous dump trucks and intelligent teleoperation with augmented reality for loaders, shovels dozers, graders and other on-site machines. For haul trucks and excavators it cites increase utilisation of up to 20-25%, and reduced maintenance cost of 10-15%, together with reduced payroll and reduced consumables. For drilling rigs VIST says it can increase utilisation up to 35%, as well as maintenance works by 10- 15% per year. The original VIST VG KARIER FMS has many specific modules that can help mines get the most out of their operations. As an example it has an optimisation module 46 International Mining | MAY 2018 that estimates the required number of dump trucks required based on the actual performance of shovels, actual travelling speed of dump trucks and other factors derived from the statistics of the current and preceding shifts. Therefore, a dispatch control operator is prevented from sending “extra” dump trucks to the work area, whose operation cannot meaningfully increase the output of shovels. This module also enables the dump trucks’ open-cycle operation with automatic control. The driver gets from the system a notification showing to which shovel his dump truck should travel after discharge, or after a significant change of the situation in mining operations (failures, etc) The optimisation module ensures the enhancement of performance by accurately estimating the required number of vehicles and directing those vehicles to the proper positions at the proper times. This functionality enables management and control actions that result in significant performance enhancement as compared to a manual system without intelligent computer-based algor ithmic optimisation. With the creation of optimisation groups, the dispatcher divides the available shovel fleet into groups, each working in an open cycle. A group may consist of a single shovel. In this case, the dump trucks assigned to it are not redistributed by the system in the process of operation. The dispatcher may manually relocate a dump truck between groups and within a group. In this case, the system sends the same notification to a driver as it does in case of automatic distribution. The driver is actually unaware of the fact of who or what is guiding his operation: software, a traffic control operator or a foreman using a workpad with software. However, every instruction is recorded in the data base and can be analysed at any time. The VG KARIER system also provides “end-to- end” fuel logging including logging of fuel in gas Summary of the platforms and functionalities that make up VIST Group’s digital mine stations, loading of fuel trucks, fuel feed form fuel trucks to vehicles, and control of fuel consumption by vehicles. Every stage of this process is subject to double and triple checks. For instance, in loading of fuel trucks the possibility of a discrepancy is checked in three measurements: change of the fuel level of an immobile storage tank, change of fuel level in a fuel truck vessel and fuel volume passed through fuel-handling facilities. This type of check is also applicable for transport vehicle refuelling. The maintenance module lets miners keep a reliable history on technical maintenance in terms of its durability, periodicity, quality, etc as well as a history and control of substituted units and devices of dump trucks, which allows mines to judge the cost of maintenance and also by implication the different results from components from different manufacturers. As with other systems it creates a complete and reliable picture of technical maintenance and repairs: where, at what time and for how long the work was taking place as well as effecting the timely planning of technical maintenance and repairs and make conclusions about the mode of operation of a vehicle. There is the option of adding scheduled technical maintenance and repairs and comparing their standards and worklists and the capability of keeping a history both for repairs and technical maintenance of a truck and all of its units and devices installed on the truck independently as well as keeping archives on installation\dismantling of units and components of a truck for which the spare capacity rate is generated. There is automatic personnel notification of the necessity of technical maintenance and automatic personnel notification about faults during operation. IM
