| Siemens supplies equipment for Lumwana Copper Mine in Zambia The Siemens Industrial Solutions and Services Group has received orders from Equinox Minerals Limited, Canada, for the supply of electrical equipment and systems for Open-Cast mine haulage trucks, Grinding Mills and "In-Pit" electrical reticulation, required for the development of its new Lumwana Copper Mine in Zambia. The order volume amounts to around 40 million euros and the new mine is scheduled to start operating in the middle of 2008. The Lumwana mine, which is located in the North Western Province of the Republic, will be the single largest copper mine on the African continent. Equinox plans to extract in excess of 400 million metric tons of ore during the first 20 years of operation producing an average of 169,000 tons of copper metal per year contained in concentrates for the first 6 years of its 37 year mine life. Siemens will supply the equipment required for the electrification for 27 haul trucks along with the associated in-pit trolley assist system. All trucks will be equipped with the latest AC drive technology. In contrast to conventional DC systems, the AC wheel motors remove the requirement for both commutators and brushes. The main component of the communications system is a fail safe fiber optic backbone known as an OTN (Open Transport Network). The fiber optic network will be utilized for the conveyance of all data and communication mediums associated with the mines operations, additionally, the transmission and provision of high-quality video signals (CVBS or S Video) will enable real-time viewing of all mine operations and critical plant equipment. The entire mining operation can thus be monitored and controlled remotely via monitors in the communications center. write your comments about the article :: © 2007 Construction News :: home page |
