This paper presents a methodology to select the most exciting business models based on renewable energy and circular economy technologies within end-of-life coal mines help develop renewable-based sector, promote sustainable local economic growth, maximise number of green quality jobs. To achieve this goal, first, structural analysis was developed technical variables that better identify complex system. Second, morphological allowed construction scenario space. Third, multicriteria...

This paper presents the possibilities of adapting active mines to generate green energy after their closure using resources and/or infrastructure. For this purpose, firstly, temporal horizon selected in Poland was determined, its basic assumption being analysis current state. In research, 18 mining plants operating within 12 Upper Silesian Coal Basin (USCB) were analyzed. The analyzed belong three five largest hard coal producers Poland, and main object exploitation is types. Severe...

Mining companies are responsible for the impacts that result from their mining activities even after period has ended. At same time, at European and international levels, there is a lack of detailed operational methodology comprising environmental risks during closure underground coal mines. The risk aspects need to be considered when planning an mine post in broader context following: modification water flow scheme, surface instability, gas emission on surface, soil pollution. In this...

The article presents the impact of lignite mining on environment associated with introduction hydro borehole (HBM) technology. results are partially based HydroCoal Plus project results, where an environmental assessment HBM technology was performed. In order to reach goals task, a life cycle (LCA) study used assess selected aspects single-borehole production process covering categories such as energy consumption, fuel water consumption and carbon footprint. LCA procedure adapted in...
