So far, bone fragments of the Pleistocene forest elephant (Palaeoloxodon antiquus) have been found only in a few sites in Poland. Almost complete skeletons were found in three of them, including one discovered in 1984 in the JóŸwin opencast, central Poland. It rested between Pleistocene glacial tills in organic sediments (peat, gyttja) of the Eemian Interglacial age. The forest elephant from JóŸwin is the most valuable palaeontological specimen ever found in the Konin Lignite Mine. It was named 'Gosław' by the local population, because its skeleton and a life-size model can be admired in the district museum in Konin-Gosławice.

The Konin region is widely considered to be the cradle of lignite mining in Poland, having probably exploited as early as the 12th century on the outskirts of the present-day town of Konin. However, not until the first half of the 20th century were lignite-rich deposits discovered. In turn, industrial lignite mining in this region was initiated by the Germans during the Second World War and has been continued by Polish crews since 1945. Thus, 80 years of Polish history of Konin Lignite Mine (KLM) will be celebrated in 2025. Over eight decades, KLM has launched several opencasts, only one of which remains at the start of 2025. During this time, hundreds of millions of tonnes of lignite (646.1 million tonnes) have been mined. In order to extract such large quantities of lignite, billions of cubic metres of water (6.14 billion m3) and overburden (3.59 billion m3) had to be pumped out and removed, respectively. In this way, the natural environment in the vicinity of Konin was strongly transformed geologically, hydrogeologically and geomorphologically. The results of these changes include numerous anthropogenic hills (external dumps) and water reservoirs (mining lakes). They, along with other post-mining areas, have been subject to reclamation since at least the 1970s. KLM is carrying out reclamation works in the following directions: water, forest, agricultural, recreational, etc. It is currently expected that lignite mining in the Konin region will most likely end in 2026–2027.

Abstract. February 2025 marks the 80th anniversary of the operation of the Konin Lignite Mine (KWB Konin/ in central Poland. During the period, lignite was extracted in 12 opencasts, of which currently (late 2024) only the Tomisławice opencast remains. Throughout the history of the KWB Konin, a total of approx. 650 mill. Mg of lignite was exploited. Lignite mining was inextricably linked to the removal of over 3.5 billion m3 of overburden and the pumping out of more than 6 billilon m3 of water. These activities led to enormous changes in the hydrogeological and geological environment, as well as transformations of the morphology of the area around the town of Konin. In the latter case, this is manifested in the occurrence of numerous external dumps and anthropogenic lakes, which are up to several dozen metres high and deep, respectively. All post-mining areas are subject to multi-directional reclamation, such as: water, forest, agricultural, recreational, etc. Finally, it is worth mentioning the open-air museums located in the vicinity of the former Konin Lignite Mine opencasts, where mining machines and equipment will be available for future generations.
