mode reaches over 9.5 percent 3MineralsFocus 2/2 | Mining RWE Power is the largest German pro ducer of electricity with around 1,0 employees and yearly output of 1 TWh. Lignite makes up good third of the installed capacity and is therefore an important pillar in the energy portfolio. With its yearly excavation of around 1 million tons, RWE Power is the worlds largest producer of lignite. Around 9 percent of the lignite excavated at the companys openpit mines in Garzweiler, Hambach and Inden is transformed into electricity. In the last years, dozen railbound stackers and reclaimers at RWE Powers Hambach and Garzweiler openpit mines have been equipped with Simine MOM for unmanned operation. Siemens entered the picture in 2 with the implementation of unmanned operation at the stockyard of the Niederauem power plant. The trigger for this project was the addi tion of new 1 GW power station to the existing lignite power plant. The cuttingedge technology implemented for the first time in this project greatly increases efficiency and therefore leads to tremendous reduction of CO 2 emissions. But in order for the technology to work, the lignite has to be of consistent quality. This target could only be ensured by introducing an integrated stockpile management system that covers quality management for the stockpile together with unmanned operation of the stockyard machines. Simine MAQ, the material and quality management system for bulk material from Siemens, is an integral part of Simine MOM. With the first implementation of Simine MOM in combination with Simine MAQ at an RWE Power stockyard, the goal to secure the delivery of the requested amount of lignite in the specified qual ity could be achieved. The availability of the equipment in driverless mode reached over 9.5 percent, which meant that for the long term the stock pile machinery could be operated without personnel.
