西门子在赞比亚获得4千万欧元电气设备订单
 
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——西门子工业解决方案与服务集团(I&S)从加拿大Equinox矿石有限公司手上获得一份订单，为后者位于赞比亚的Lumwana新铜矿厂提供开发所需要的电力设备以及用于露天挖掘矿山运输车、磨碎机和“矿井内”电力网的系统。订单量总计大约为4千万欧元，新矿厂预计在2008年中开始投入运营。 

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.

位于赞比亚共和国西北省的Lumwana铜矿厂将成为非洲大陆上单个最大的铜矿厂。Equinox计划在投入运营的前20年内提取超过4亿公吨的矿石，在37年矿山开采年限的前6年，平均每年生产矿石中含有的铜金属16万9千吨。该矿厂还含有丰富的金、钴和铀资源，在不久的将来也有可能提炼出来。

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.

为了矿石从坑内到粉碎场的运输，西门子将提供27辆拖运车电气化所需要的设备以及相关的矿井内滚轮辅助系统。所有的拖运车都将装备最新的交流驱动技术。与传统直流电系统相比，交流车轮马达无需换向器和电刷，这极大减少了维护和维修成本，同时提高了设备的实用性。此外，所使用的驱动技术应用的一个电减速刹车系统，将保证机械制动器更高的安全和更少的磨损。滚轮辅助系统沿着主要的拖运斜坡路线安装，使得拖运车可以与传统轨道系统相同的方式获得交流车轮马达所需要的电力。本系统带来的其他好处还包括高起动转矩，同时得到更快的速度从斜坡运出矿井，而更高的速度带来更短的循环周期，同时滚轮的运转节省了可观的柴油燃料成本。

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.

为了连续监视所有的采矿作业，西门子将提供一个综合通信系统。该通信系统的主要构成是一个自动防故障的光纤高速链路，称为开放式运输网络（OTN）。该光纤网络将用于传输与采矿作业相关的所有数据和通信媒介，而且，高质量视频信号(CVBS 或者 S Video)的传输和提供将使得可以实时观察所有采矿作业和矿厂关键设备，比如压碎机、陆上传送带、泵、采矿吊索等等。因而通过通信中心的显示器可以远程监视和控制整个采矿作业。

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.

通过"eWD"电子文件系统的帮助，一套与磨碎机安装细节相关的综合文件和信息在调试阶段产生，这就保证了所有的相关信息都可以联机以帮助维护和优化磨碎机。

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. 

西门子装备该新矿厂整个“矿井内”电力设备。所有的设备将由西门子开发、制造、安装和调试。首要的设备维护也包含在项目范围里。该矿厂预计在2008年下半年开始生产。
