In this article, the conditions and determinants of the introduction and development of the circular economy (CE) in Poland were presented against the background of the widely discussed essence of circular economy, with particular emphasis on the Polish mining sector. In addition, the European Green Deal—an action plan for a sustainable economy for the entire European Union, was discussed. Particular attention was paid to the role of human resources in the area of supporting research and stimulating innovation, and in the area of activating education and training. These issues are further discussed in the next chapter by presenting the forms, ways and scope of education for sustainable development in the international context. Another chapter describes the EIT Raw Materials KAVA 5 RIS competition in Poland (in Kraków) at AGH-UST from 2019 to 2022, an international project in a consortium of four universities whose main objective is to strengthen entrepreneurship in the V4 countries in line with the recommendations of the “Green action plan for SMEs” in a way to meet the requirements of circular economy. The initiatives and trainings carried out within the framework of this project were discussed, and the results of the student survey on the level of knowledge achieved regarding entrepreneurship in the area of the raw materials industry were analysed. The validity and necessity of continuous education in eco-responsible citizenship has thus been confirmed.
Method of the influence of assessment of longwall effective working time onto obtained mining output, has been discussed in the present study.Mean flow rate of the winning stream being also considered as directional factor of linear function describing relation between daily output and effective mining in the longwall face, has been determined.Such relation -presented also graphically in form of the diagram -determines significance and influence of the effective working time onto obtained mining output. This relation should be considered as motivation in particular for supervisory personnel, as it shows advantages resulting from elongation of this time, as well as it shows possible loses of the daily output in a case, when the effective working time in given longwall face was shortened.Keywords: longwall faces, production process, daily output, effective working time, effectiveness of production processTreścią pracy jest metoda oceny wpływu efektywnego czasu pracy w ścianie na uzyskiwane wydobycie.Wyznaczane jest średnie natężenie strugi urobku, będące jednocześnie współczynnikiem kierunkowym funkcji liniowej, opisującej zależność wydobycia zmianowego od efektywnego czasu pracy w przodku.W ten sposób wyznaczona zależność -prezentowana także graficznie w formie wykresu -zwraca uwagę na znaczenie i wpływ efektywnego czasu pracy na uzyskiwane wydobycie. Powinna działać motywacyjnie (w szczególności chodzi o pracowników dozoru ruchu), gdyż pokazuje korzyści wynikające ze zwiększenia długości tego czasu, ale także pokazuje możliwości strat w wydobyciu zmianowym, jeśliby efektywny czas pracy w danym przodku ścianowym uległ skróceniu.Słowa kluczowe: przodki ścianowe, proces produkcyjny, wydobycie zmianowe, efektywny czas pracy, efektywność procesu produkcyjnego
This article presents the challenges that mining companies have in the face of the Industry 4.0 philosophy. Transformation of mining businesses into Industry 4.0 appears unavoidable. Due to the specific nature of the sector, the transformation will not be an easy one. This paper discusses the obstacles and challenges related to the transformation of businesses in the mining industry into the Industry 4.0. The history of industrial revolutions was presented, also as the idea of Industry 4.0 with its basic components. The concept of Industry 4.0 is also outlined and the studies which indicate the key issues in the transformation process are also cited. Based on these studies, it can be seen that the vast majority are issues in the field of production engineering and properly educated and qualified staff. Four main areas in which transformation into Industry 4.0 should be taking place are identified. Particular emphasis is placed on the area of technology and organizational culture. The mutual relations of management functions and ICT technologies have also been presented, which is one of the elements of the idea of Industry 4.0. Finally, the potential benefits for the organizational culture of the business of implementing the Industry 4.0 concepts are discussed.
