OTTAWA — The Organization for Economic Co-operation and Development has raised its expectations for economic growth in Canada this year compared with a June forecast.The Paris-based economic think tank says it now expects the Canadian economy to grow by 3.2 per cent this year, best in the G7.That is up from its forecast in June for growth of 2.8 per cent.The OECD maintained its Canadian outlook for 2018 at 2.3 per cent.Meanwhile, the organization’s outlook for global economic growth was unchanged at 3.5 per cent for this year and up slightly at 3.7 per cent for 2018, compared with 3.6 per cent in its previous forecast.Expectations for the U.S. were unchanged at 2.1 per cent this year and 2.4 per cent next year.
Bucyrus, a leading mining equipment manufacturer, has won a contract to deliver a complete automated plow longwall to Polish mine operator Lubelski Węgiel Bogdanka for its Bogdanka mine in Puchaczów, 29 km from Lublin in eastern Poland. It is the first complete plow longwall system sold into Poland. The longwall will initially start to operate on a 250 m working panel and will finally operate on a 305-m working panel of seam 385, which has a thickness of between 1.4 and 1.8 m. A Gleithobel® GH1600 plow will be installed, which has 2 x 800 kW of installed power and has been specifically developed for high productivity in very hard coal. A total of 173 roof supports – with a support range of 950 – 2,000 mm – will be supplied, each equipped with its own PMC®-R roof support control. Other members of the Bucyrus Programmable Mining Control family will also be used for automation and visualisation: The PMC-D (drive control) and PMC-V (visualisation) for the 2 P45-UEL overload-protected plow drives and the 2 P45-CST (controlled start transmission) face conveyor drives.The longwall will be equipped with a PF4/1032 face conveyor, a PF4/1132 entry conveyor, a SK 1111 crusher and an S147600 belt tail-piece. Power supply and pump station will also be supplied.With installed power totalling 3.3 kV – 2 x 210/630 kW for the plow and 2 x 800 kW for the armoured face conveyor – the longwall system will be delivered to the customer at the end of the 2009. The complete system was ordered as Bucyrus was able to ensure a daily production rate of 10,000 t.Bogdanka is one of Poland’s major mine operators, producing 7.86 Mt of raw coal in 2008. The company has over 3,650 employees.
Mining fleet management specialist Leica Geosystems has launched its GPS Augmentation Network, incorporating exclusive technology developed by Locata Corp. The innovative terrestrial network ensures 24/7 positioning coverage even with adverse GPS situations. Open pits can present challenges for satellite based positioning as the pit becomes deeper, and where the walls are steep. The positioning signals transmitted from satellites can become obstructed by the pit walls, reducing GPS availability and in turn, accuracy. The angle of ‘sky view’ is further reduced where machinery is in close proximity to the pit walls which block GPS signals. Leica’s GPS augmentation network fills these shortcomings in the GPS network and ensures consistent and accurate positioning is always available. Under an exclusive technology partnership with Locata, Leica’s Jigsaw360 is the first fleet management system with the ability to replicate the GPS satellite constellation from the ground. This ground breaking technology enables a level of control and flexibility which is not possible from the standard satellite GPS network.With this development, Leica Geosystems and Locata have made a significant advance in the availability of consistent positioning signals. The efficiency and productivity benefits of total positioning coverage also have the potential to solve other problems where the standard GPS network has fallen short in the past. For example, GPS collision avoidance systems, and for automated mining developments. In these applications, constant and accurate positioning is critical to safe operation. Consistent and accurate GPS coverage across the deepest and steepest pitsComplete positioning availability ensures the highest efficiency and productivity gains from Leica’s Jigsaw360 fleet management and machine control systemsA significant step in the development of reliable collision avoidance and automated mining systems.
