Wind Power Plants and Selected Technical and Economic Aspects of Their Construction on Mine Heaps

As a result of energy transformation and decarbonization, the production of hard coal and lignite mining plants is gradually being phased out. Mine heaps, i.e., mine waste heaps, created as a result of the operation of these plants, are not attractive as land for housing, for the construction of production plants, or for agriculture. One of the most advantageous ways of recultivating these areas is using them as a place for the installation of renewable energy sources. In the case of post-mining heaps, it seems natural to use photovoltaics and wind turbines due to the artificial elevation of the terrain. This issue was analysed within the RFCS project SUMAD (Sustainable Use of Mining Waste Heaps). Experts from various countries and scientific disciplines analysed possible scenarios for the mine heaps' management, with a special attention to geotechnical, environmental and socio-economic challenges. This article discusses one of the variants, namely the possibility of constructing the wind turbines on mining heaps.
