VDMA 21 2019 • VDMA MINING SUPPLEMENT yard Management System," said Peter Muehlbach, ABB's vice-pres- ident of process industries, Germany. Informed by ABB's proven heritage of providing electrification and automation for open-pit mining and bulk material handling ap- plications, the ABB Ability Stockyard Management System (SYMS) can now address the challenge — particularly at integrated lignite mine and power systems in Europe — of different mines feeding a nearby thermal generation plant without additional coal processing. Influenced by non-ideal coal seam sources, the quality of the mined lignite in terms of calorific value, ash and sulphur content is highly variable. In order to ensure an efficient combustion process, the coal feed has to be homogenized at stockyards using selective mining and blending processes. ABB's Ability SYMS uses belt scales and online analyzers to monitor the quantity and quality of excavated coal directly on con- veyer lines. The system begins by comparing the parameter from the production planning system — based on the geological model of the coal deposit — with the real measured values. It then creates a feedback loop to the production system, calcu- lates new excavating and blending process parameters, and trans- mits them directly to the mine's control system and the stockyard. "Fueling a power plant relies on a blended mix of different coal qualities, which is normally done on a stockyard," Muehlbach said. "Tracking the quality and volume of the coal, and then carrying out the blending process remotely on the conveyor line on the way from the mine to the power station, is really something new, especially in terms of commercial lignite production." Following implementation at Vale's iron ore distribution hub in Malaysia, the SYMS can now deployed apart from terminals and ports also in continuous coal mining operations. The application integrates all relevant systems with dozens of features in order to facilitate proactive production planning, qual- ity management, production controlling, fully automated yard ma- chines and semi-automated mine operation. ABB's global footprint can also be perceived in Chile, where it partners with TAKRAF Tenova Chile to supply large-scale gearless conveyor drives (GCDs) to state-owned Codelco for use in the exten- sion of the Chuquicamata copper mine. The Chuquicamata Under- ground project is home to the world's largest conveyor system (55 MW installed power) connecting the subterranean operation directly to the concentrator. GCD installations such as these, with up to 6MW single motor power, promise to improve reliability and system efficiencies, as well as profitability and safety resulting from reduced maintenance. While large conveyor installations are stationary, open-pit or IPCC conveyors have to be moveable as they shift with the bank — as a result, they require a different approach to gearless drive design. ABB's solution for the medium power range (1 to 3 MW per mo- tor) incorporates a permanent magnet motor specifically designed for mining applications, making the technology economically feasi- ble for a broader range of conveyor equipment, including on mobile equipment, as Ulf Richter, product manager, conveyor systems at ABB Process Industries, Mining, explained. "ABB's new GCD for medium power with permanent magnet (PM) motor reduces the drive train's failure rate by 50% and im- proves energy efficiency," he said. "Different mounting variants enable application-optimized use in both, new or retrofit conveyors. "A test project established the feasibility of installing GCDs on mobile mining machines and shows the suitability of permanent magnet torque motors to drive conveyors. The results reveal that GCDs are viable alternatives to conventional geared drives." Operatio nal Excellence Training.
