Lignite opencast mining
A large energy company extracts lignite on its mining fields in opencast mining operation using a special excavation and conveying technology. Compared to other methods in which the soil layers covering the lignite are transported around the surface mine using belt conveyor systems, this technology requires much shorter transport routes. These short transport routes are elementary for a productive excavation of the lignite and are highly frequented. The energy company uses a mobile Börger rotary lobe pump for pumping out the water accumulations. The pump is resistant to solids and is installed on a three-point hitch frame.
