Siemens receives 40 million euros electrical equipment orders in Zambia 

西門子在贊比亞獲得4千萬歐元電氣設備訂單

Erlangen, Mar 26, 2007 -- The Siemens Industrial Solutions and Services Group (I&S) 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.

Erlangen3月26日消息——西門子工業解決方案與服務集團(I&S)從加拿大Equinox礦石有限公司手上獲得一份訂單，為后者位于贊比亞的Lumwana新銅礦廠提供開發所需要的電力設備以及用于露天挖掘礦山運輸車、磨碎機和“礦井內”電力網的系統。訂單量總計大約為4千萬歐元，新礦廠預計在2008年中開始投入運營。 

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. The mine also has resources containing significant quantities of Gold, Cobalt and Uranium which may also be extracted in the near future.

位于贊比亞共和國西北省的Lumwana銅礦廠將成為非洲大陸上單個最大的銅礦廠。Equinox計劃在投入運營的前20年內提取超過4億公噸的礦石，在37年礦山開采年限的前6年，平均每年生產礦石中含有的銅金屬16萬9千噸。該礦廠還含有豐富的金、鈷和鈾資源，在不久的將來也有可能提煉出來。

For transportation of the ore from pit to crushing stations, 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. This significantly reduces the maintenance and repair costs, while increasing the availability of the units. Moreover, the drive technology employed will ensure greater safety and less wear on mechanical brakes due to the availability of an electrical retarder braking system. The trolley assist system to be installed along the main ramp haulage routes allows for the trucks to draw the electricity required for the AC wheel motors in much the same way as conventional railway systems. Additional benefits derived from this system are high starting torques, and increased speeds whilst on the gradient exiting the pit, the higher speeds result in increased cycle times whilst operation on trolley realizes huge savings in diesel fuel costs.

為了礦石從坑內到粉碎場的運輸，西門子將提供27輛拖運車電氣化所需要的設備以及相關的礦井內滾輪輔助系統。所有的拖運車都將裝備最新的交流驅動技術。與傳統直流電系統相比，交流車輪馬達無需換向器和電刷，這極大減少了維護和維修成本，同時提高了設備的實用性。此外，所使用的驅動技術應用的一個電減速剎車系統，將保證機械制動器更高的安全和更少的磨損。滾輪輔助系統沿著主要的拖運斜坡路線安裝，使得拖運車可以與傳統軌道系統相同的方式獲得交流車輪馬達所需要的電力。本系統帶來的其他好處還包括高起動轉矩，同時得到更快的速度從斜坡運出礦井，而更高的速度帶來更短的循環周期，同時滾輪的運轉節省了可觀的柴油燃料成本。

For continuous monitoring of all mining operations, a comprehensive communication system will be supplied. 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 such as crushers, over-land conveyors, pumps, mine fleet etc. The entire mining operation can thus be monitored and controlled remotely via monitors in the communications center.

為了連續監視所有的采礦作業，西門子將提供一個綜合通信系統。該通信系統的主要構成是一個自動防故障的光纖高速鏈路，稱為開放式運輸網絡（OTN）。該光纖網絡將用于傳輸與采礦作業相關的所有數據和通信媒介，而且，高質量視頻信號(CVBS 或者 S Video)的傳輸和提供將使得可以實時觀察所有采礦作業和礦廠關鍵設備，比如壓碎機、陸上傳送帶、泵、采礦吊索等等。因而通過通信中心的顯示器可以遠程監視和控制整個采礦作業。

With the help of the "eWD" electronic documentation system, a comprehensive suite of documentation and information pertinent to the specific mill installation is generated during the commissioning phase. This ensures that all the relevant information is available online to facilitate maintenance and optimization of the mills.

通過"eWD"電子文件系統的幫助，一套與磨碎機安裝細節相關的綜合文件和信息在調試階段產生，這就保證了所有的相關信息都可以聯機以幫助維護和優化磨碎機。

Siemens is to equip the new mine with the entire “In-Pit “electrical infrastructure. All the equipment will be developed, built, installed and commissioned by Siemens. First-Line maintenance of the equipment is also included in the project scope. The mine is scheduled to begin production during the second half of 2008. 

西門子裝備該新礦廠整個“礦井內”電力設備。所有的設備將由西門子開發、制造、安裝和調試。首要的設備維護也包含在項目范圍里。該礦廠預計在2008年下半年開始生產。
