    Opis:
    Energy and climate issues are an essential part of the sustainable development process of the EU countries. They are also one of the primary objectives of international policy, as evidenced by their inclusion in Agenda 2030, adopted by the UN in 2015 among the Sustainable Development Goals. The implementation of these goals is also taking place in the EU countries. Although climate protection and energy transition activities have been undertaken in the EU for years, individual countries significantly vary in this regard. The aim of the research, the results of which are presented in this paper, was to analyze similarities between the EU countries in terms of sustainable energy and climate development. The analysis was conducted for all EU countries, based on 14 indicators characterizing energy and climate sustainability, in energy, climate, social and economic dimensions. Kohonen’s artificial neural networks were used for analysis. The research was conducted for data from the period between 2009-2018. The results showed that in the studied period (10 years), significant differences were found between the EU countries. A high level of energy and climate development was reported for Sweden, Denmark, Austria and France, among other states, and a low level for e.g., the Czech Republic, Poland and Bulgaria.

    Opis:
    Hard coal mines and mining enterprises involved in hard coal exploitation in the area of the Upper Silesian Coal Basin (Górnośląskie Zagłębie Węglowe) are characterised by the presence of natural hazards typical of this type of exploitation. These hazards include the risks related to methane, coal dust explosion, endogenous fires, as well as rock burst and caving of roof rocks. The article presents the results of a taxonomic analysis aimed at determining the similarity of hard coal mines and mining enterprises in Poland in terms of the dangerous incidents caused by the risks related to methane, coal dust explosion, endogenous fires, as well as rock burst and caving of roof rocks. The analysis was carried out for the 2008-2018 data and encompassed a total of 26 hard coal mines and mining enterprises located in the Upper Silesian Coal Basin. The analysis was performed using the k-means method of non-hierarchical clustering. The main objective of the article was to determine homogenous groups (clusters) of mines exhibiting the greatest similarity in terms of dangerous incidents caused by the activation of natural hazards in the years 2008-2018. These data can be successfully used for the development of preventive measures and risk analyses for these enterprises.

    Analysis of Gas and Dust Emissions From the Mining and Quarrying Sector in the European Union Countries

    European Union countries
    Opis:
    Despite the ongoing changes in the energy and economic structure of the European Union countries, mineral and energy resources such as hard coal, brown coal, natural gas, copper ores, zinc ores and many other minerals continue to be extracted. Each year, the mining and extraction sector emits thousands of tons of harmful substances into the atmosphere, in the form of greenhouse and other air-polluting gases, as well as harmful dusts. These substances include, amongst others, carbon dioxide, methane, carbon monoxide, as well as PM2.5 and PM10. The European Union climate policy clearly recommends that the exploitation of mineral resources be carried out in full respect of the principles of their rational, economical and environmentally neutral acquisition, which is confirmed by the promoted strategy of sustainable development economy. Therefore, this means the necessity to undertake actions aimed at limiting the emission of greenhouse gases and air pollutants into the atmosphere. To assess the actions taken by the European Union countries to date with respect to limiting those emissions, a comparative analysis was carried out for the particular countries. This analysis encompassed the emission of harmful substances from the mining and quarrying sector by the European Union countries in the years 2008 and 2017. The purpose of the analysis was to show the diversity of those countries in terms of the emission of harmful gases and dusts, as well as to divide them into similar groups. Such a division paves the way for developing a common climate policy and exchanging experiences between the countries from the particular groups. The European Union countries were divided into similar groups using the k-means grouping method. Comparison was also made for the emissions of the substances under analysis for the particular countries over the research years. The results obtained unequivocally demonstrate that this emission has been limited in the European Union, but there are countries where the emission of certain substances has increased.
