The lignite is uncovered by surface mining. Surface mining is a method of mining whereby the overlying materials are removed to expose the mineral for extrac-tion. The equipment used during overbur-den stripping operations are draglines and motorized scrapers. A dragline is an excavating machine that utilizes a bucket
The most common exploitation method in PPC's surface lignite mines is the continuous surface mining method (sometimes referred to as the German method, or in older references, the terrace mining method) using bucket wheel excavators. Lignite and waste material are usually transported by conveyor belts, while spreaders are used for dumping.
