2 The challenge: Lowering operation costs and increasing availability The challenge in open-cast mining Competitive pressures continue to grow in open-cast mining. To be successful, mining companies must continually optimize extraction costs and simultaneously ensure that the required quantities of materials in the required quality are extracted. There are various ways to achieve this: with rugged technology that at the same time responds sensitively, and that can withstand the harsh requirements of normal open-cast mining operations. We offer transparency throughout the entire process. At places where every excavator conveys up to 240,000 m 3 every day, it s easy to estimate the consequences of a potential system failure. That s why maximum availability, based on gentle operation of bucket chain and bucket wheel excavators, is mandatory in open-cast mining. Although the environment is harsh and system dimensions are huge, the technology must be sensitive so that it can be adjusted to the geological conditions. The challenge for materials transport If you want to transport materials profitably, you must keep in mind two key requirements: K Ensure safety and reliability in daily operations K Minimize storage times to reduce capital lock-up A balanced solution for stockyard equipment must therefore address several points. It must ensure optimum material flow based on precise information regarding material composition, quantities and storage locations. It must provide high-performance diagnostics and be easy to handle. And it must be flexibly tailored to suit the requirements of your plant, up to and including fully automatic operation. Two tasks one answer Whether for continuous handling equipment or materials transport, with SIMINE CIS EXC we offer a complete solution for continual extraction in open-cast mining. The solution focuses on safety and reliability of operations while maximizing output to reduce the costs per extracted ton. SIMINE CIS EXC includes all the necessary modules for this purpose, from proven automation technology to simplified and streamlined maintenance. In addition, with SIMINE CIS EXC you can boost efficiency in materials transport in coal-fired power stations, steel works and processing plants. The benefits result from innovative solutions to the processes of dropping off, reclaiming and conveying as well as time- and volumeoptimized logistical concepts. Our services safeguard high levels of performance right from the start and across the entire life cycle.

5 Our solution for open-cast mining: Higher performance, lower maintenance costs SIMINE CIS EXC is the complete electrical engineering, drive, automation and service package for bucket wheel and bucket chain excavators, from compact equipment up to large excavators that transport up to 240,000 m 3 daily. Higher performance more reliability greater safety With SIMINE CIS EXC excavators can be loaded to their performance limits, while avoiding load peaks that would sharply increase the wear and tear and maintenance requirements. A high degree of reliability is guaranteed right from the start, as specially developed low- and high-voltage switching stations provide an uninterrupted power supply. SIMATIC S7, our innovative and proven automation system, also guarantees reliability, especially when coupled with our variable-speed drive solutions. Higher performance owing to new automatic conveying system The uniform utilization of the conveyor allows you to exactly specify the desired conveying throughput and thus to better control the volume. Peak loads are avoided, availability is increased, and mechanical stress is reduced. Lower maintenance costs through gentle mechanic control High mechanical stress causes components to wear out faster and leads to unnecessarily high maintenance costs. Less work for everyone from equipment operators to service personnel Automation and special tools for equipment operators support your personnel so that they can fully concentrate on their essential tasks. Through the use of the master-value transmitter specially developed for opencast mining, selected setpoint values for automatic slewing angle limiting, cutting and cutting depth and cutting height are approached at the optimal time. Specified physical limits such as maximum speed, acceleration, deceleration and jolt are reliably adhered to. Consistency checks minimize potential operating errors, and convenient visualization systems help the "man in the driver's cab" to control the device confidently in all situations. At the same time, intelligent systems allow service personnel to detect and eliminate errors quickly and easily. Homogeneous system landscape, high service-friendliness Whether drive engineering or automation, whether control and monitoring in the higher-level control center all systems are connected to one another end to end. This results in simple and secure exchange of data and simple project planning, while the number of required interfaces seems to automatically decrease on its own. This can be avoided with a package of control engineering measures that stabilizes oscillating systems, cushions load surges and also controls gearless devices. As a result, the life of mechanical equipment is provably lengthened while maintenance costs are reduced. 4 5

6 For decades we have been leaders in the automation, visualization and optimization of material handling processes. The expertise we gained has been integrated into SIMINE CIS EXC, allowing us to offer flexible solutions for continuous handling equipment as used for example in transshipment depots, coal-fire power stations, steel works and processing plants. We also offer the facility for integration with higher-level material management solutions. Our solution for materials transport: Efficient storage area operation through precise quality management Total concepts for total optimization Integrated SIMINE CIS EXC concepts make sure your material logistics are in top form. Every concept is based on the precise, IT-supported acquisition of volume and material data. K In transshipment depots we ensure that optimum use is made of the storage areas irrespective of the bulk material being handled and we also minimize vessel turnaround times. We keep your materials on the move to make sure your processes are profitable. K In coal-fired power stations we make more effective use of storage area and safeguard the correct mix of materials with varying calorific values to maximize efficiency. K In mixed storage yards at steel works and processing plants, with SIMINE CIS MAQ we make it possible to mix a variety of materials with accuracy and precision in order to guarantee the qualities required thus avoiding expensive quality give-aways. Plus, volumecontrolled reclaiming satisfies another practiceoriented requirement. Individual systems diagnosis included Our systems designed for loading, reclaiming and conveying provide a basis for efficient storage depot operations pushing the limits of what is technically feasible and economically practical. Integrated reporting and diagnostic systems simplify plant handling and maintenance: error elimination times are significantly reduced and availability is increased. For years now we have been implementing fully automatic solutions for stackers, reclaimers and combined systems. SIMINE CIS MAQ is the IT-assisted 3D dump data acquisition, which allows safe approach, drop-off and reclaim operations without risking material losses. SIMINE CIS MOM enables automation in manless operation. Several pieces of dump equipment can be operated from a central control station. Laser scanners determine the surface profile of the dump. Together with the exact position of the dump equipment, this 3D surface profile provides the basis for automated control of the dump equipment. We optimize conveyor operations with the aid of regulated drives that permit variable speeds dependent on load. Integral to such solutions are reliable automated material monitoring and integrated safety circuits designed to protect operating personnel, as well as the technology itself. Our services ensure your success It s crucial to ensure top performance throughout the entire life cycle of your plant. We make sure you achieve that goal with our professional services ranging from financing and planning to design, integration and commissioning, as well as remote diagnosis and ongoing maintenance and repairs to ensure high availability.
