The article discusses the specifics of working in the mining industry and the associated challenges for individuals with ADHD. Underground work requires high levels of concentration, psychological resilience, and strict adherence to safety procedures. Individuals with ADHD may struggle with sustained attention, work organization, and rule compliance, which can increase the risk of accidents. At the same time, their ability to respond quickly to changes and adapt to a dynamic environment can be an advantage.The article presents the results of a survey conducted among 67 working men diagnosed with ADHD. The findings indicate that 73% of respondents perceive ADHD as an obstacle at work, while 58% recognize an increased risk of accidents. Additionally, these individuals reported difficulties with multitasking and following procedures.Based on these findings, the article proposes strategies to support the adaptation of individuals with ADHD to mining work, such as adjusting the work environment, providing training to increase supervisors' awareness, and offering individualized psychological and organizational support. The article highlights the necessity of implementing appropriate support mechanisms to improve the safety and efficiency of neurodivergent workers in the mining industry.

This article presents selected properties of mixtures produced from two types of fly ashes from one coal-fired power plant. Mixtures made of fly ashes from a conventional boiler without flue gas desulfurization products (10 01 02) and from a fluidized bed boiler with flue gas desulfurization products (10 01 82) are subjected to testing. The mixtures are prepared using mine water. The tested mixtures are characterized by a liquid consistency in terms of flowability in a range from 160 mm to 280 mm. The mixtures made of 10 01 82 ashes show twice as much water demand, shorter setting time, and higher strength than those made of 10 01 02 ashes, but, unfortunately, they have a much higher volume of excess water. Moreover, the mixtures of 10 01 82 ash do not undergo full slaking, in contrast to the mixtures of 10 01 02 ash (conventional boiler). The requirements of the PN-G 11011:1998 standard, relative to the discussed parameters, are met by the mixtures made on the basis of ash 10 01 82 originating from a fluidized bed boiler in terms of flowability of up to 240 mm. This is the ash type useable in sealing technology.

Nothing stays the same. The only thing you can be sure of in life is change. Trudi Canavan Purpose: in the cognitive space of the article, an important and significant challenge arises, which is - in the perspective of the megatrends indicated in the article, demographic change and public health - the need to prepare a package of socio-economic activities dedicated primarily to the inhabitants of the areas where the process of closing down mining plants will take place. In this context, the issues of demographic change and health should be given priority in these areas in activities promoting social and economic activity in the transformation process. Methodology: the theses presented in the article were verified using the following methods: literature review, critical analysis of literature, analysis and comparison of documents and an example of good practices. Resultat: in the perspective of the next decades, numerous social and economic challenges and effects related to the transformation of mining plants in the space of local communities (commune, district) can be pointed out. While maintaining the hierarchy of objectives described in the European Green Deal Plan and clearly related to the plan for the transformation of mining plants, lasting cooperation of the three key stakeholders in this process, i.e., local communities (representation of local and territorial self-government), employers and representation of state policies, should be expected in their environment. Originality: the conclusions and recommendations from the article may be important for researchers and practitioners involved in the implementation of activities aimed at limiting the marginalization, differentiation and social and economic exclusion of residents of areas where the process of closing mining plants will take place.

Your goal must be to get everything without destroying anything. Sun Zi Purpose: in the cognitive space, the article focuses on the issue of dynamically growing social awareness of the impact of hard coal on climate change - which determines the need to implement a strategy to abandon this raw material. The authors of the article also point out that in connection with this process - as the world strives for sustainable and more ecological development - the transformation of the hard coal mining sector becomes an inevitable challenge. Methodology: the theses presented in the article were verified using the following methods: literature review, critical analysis of literature, analysis and comparison of documents and an example of good practices. Resultat: properly managing the transformation of the hard coal mining sector is key to ensuring that it delivers long-term social and economic benefits - while minimizing the negative impact of the transformation on mining communities and workers in the hard coal mining sector. Therefore, a holistic approach is important in this space, taking into account the ecological, economic, political and social context of transformation. Originality: the transformation of mining is necessary due to the sustainable development goals, environmental protection and the fight against climate change. It is also a political challenge that requires well-thought-out investments, policies and regulations to minimize the negative socio-economic effects of the transformation and to use the development potential of the transformed areas in all their dimensions.

W artykule przedstawiono możliwość zastosowania w górnictwie podziemnym dwóch rodzajów popiołów lotnych pochodzących z energetyki zawodowej spalającej węgiel kamienny. Badaniom podano mieszaniny wytworzone z popiołów lotnych pochodzących z kotła konwencjonalnego bez produktów odsiarczania spalin (10 01 02) oraz kotła fluidalnego z produktami odsiarczania spalin (10 01 82). Mieszaniny sporządzono wykorzystując wodę kopalnianą o gęstości 1023 g/dm3. Badane mieszaniny miały konsystencję płynną o rozlewności w zakresie 160-280 mm. Mając na uwadze uzyskane wyniki badań oraz wytyczne normy PN-G 11011:1998 należy stwierdzić, że w zakresie omawianych parametrów mieszaniny wytworzone na bazie popiołu pochodzącego z kotła fluidalnego (10 01 82) spełniają jej wymagania w zakresie rozlewności 160-240 mm, jedynie w technologii doszczelniania. W technologii podsadzki zestalanej żadna z zbadanych mieszanin nie spełnia ww. normy. Ponadto stosując w górnictwie podziemnym mieszaniny z popiołu lotnego bez produktów odsiarczania spalin pochodzącego z kotła konwencjonalnego należy dokładnie rozważyć jego możliwość, technologię w której ma być stosowany, a przede wszystkim miejsce jego aplikacji.

The paper presents the possibility of using two types of fly ash from utility power plants burning hard coal in underground mining. Mixtures made from ﬂy ash from a conventional boiler without ﬂue gas desulphurisation products (10 01 02) and a fluidised bed boiler with ﬂue gas desulphurisation products (10 01 82) were tested. The mixtures were prepared using mine water With a density of 1023 g/dm3. The tested mixtures were of liquid consistency with a ﬂowability of 160-280 mm Taking into account the obtained test results and guidelines of the PN-G 11011:1998 standard, it should be stated that, in terms of the discussed parameters, mixtures produced on the basis of ash from the ﬂuidised bed boiler (10 01 82) meet its requirements in the range of ﬂowability of 160-240 mm, only in the case of the backﬁlling technology. In solidifying backﬁll . technology, none of the mixtures tested comply with the aforementioned standard. In addition, when using ﬂy ash mixtures without ﬂue gas desulphurisation products from a conventional cat (10 01 02) in underground mining, careful consideration must be given to its feasibility, the technology in which it is to be used and, above all, where it is to be applied.

The article is based on practical experience and research, presenting the author's concept of applying the principles of cybersecurity of IT/OT systems in key functional areas of a mining plant operating based on the idea of INDUSTRY 4.0.In recent years, cyberspace has become a new security environment, which has introduced significant changes in both the practical, and legal and organizational aspects of the operation of global security systems. In this context, it is particularly important to understand the dynamics of this environmental change (both in the provisions of the NIS 2 directive and the KSC Act) [1]. Building a legal system as a national response to the opportunities and challenges related to its presence in cyberspace was an extremely complex task. This results not only from the pace of technological change, but also from the specificity of the environment and its "interactivity". The trend in international law that has emerged during COVID-19 and the current geopolitical situation is to treat organizations from the mining and energy sector as one of the important actors in national and international relations [2].The new regulations introduce and expand international cooperation between individual entities and regulate security strategies and policies, which should take into account the recommendations of the Ministry of Climate and Environment, with particular emphasis on, among others, ensuring the continuity of system operation, handling security incidents and constantly increasing awareness of cybersecurity and cyber threats. It should not be forgotten that threats in cyberspace represent a different class of organizational challenges, largely similar to those posed by other asymmetric threats such as terrorism. Their common feature is that they require less hierarchical and more flexible solutions on state structures. Cybersecurity, both socially and technologically, with all its consequences, emerges as one of the most important concepts of the security paradigm at the national and international level [3].

Centuries of gold-arsenic ore mining activities in Czarnów village within the Evelinens glück mine (SW Poland) have left an enduring impact on the local environment, characterized by distinct geochemical anomalies and contamination in water and plants. We have comprehensively investigated the spatial distribution of arsenic and metals in soils, plants, and water in close proximity to post-mining dump sites. The findings reveal striking anomalies in the vicinity of the mine, notably elevated levels of arsenic, zinc, lead, copper and cobalt. The highest recorded arsenic content surpassed 290,000 ppm, with cobalt reaching almost 18,000 ppm and copper exceeding 21,000 ppm. This contamination was most pronounced around mining excavations and in the immediate vicinity of mining dumps. Additionally, pore water analysis from the study area uncovered elevated arsenic levels, surpassing permissible standards, with concentrations exceeding 600 ppb. Moreover, plant specimens (Rubus idaeus, Deschampsia flexuosa, Dryopteris carthusiana) in the region were observed to accumulate arsenic and other toxic elements, with Rubus idaeus recording the highest arsenic concentration at 19.00 ppm. These accumulations consistently exceeded established environmental norms. The presence of such elevated concentrations of toxic elements in both soil and plant life underscores profound concerns for human health, with potential implications for a range of health issues.

The transformations and deformations accompanying mining exploitation adversely affect the surface and its development facilities, leading to damage to building structures and technical infrastructure. These inconveniences often become a source of social conflicts and tensions, especially in highly urbanized areas. Mining companies face the difficult task of carrying out their activities while simultaneously preventing and eliminating mining damages that occur during and after the exploitation of deposits. In this article, the authors have collected a number of factors characterizing mining activities to determine their nature and impact on buildings located in mining areas. These factors were subjected to DEMATEL analysis, which made it possible to examine the strength of their impact as well as their cause-and-effect relationships. The cause-and-effect analysis enabled the identification of the relationships between the mining factors affecting buildings and the determination of their nature. This analysis will facilitate the easier determination and subsequent planning for the reduction of adverse effects of mining activities in areas affected by mining exploitation.

Post-mining grounds and spoil tips frequently render landscapes permanently flawed. As a result of mining activity, considerable stretches of land are often permanently excluded from further use. Due to the extensively transformed landscape, it is necessary to implement revitalisation processes. Relevant design and investment activities, coupled with the cooperation of specialists such as architects, civil engineers, geotechnicians, hydrotechnicians and environmental engineers, along with local authorities, can offer a comprehensive functional programme for areas degraded by mining and provide local residents with an attractive leisure area. This article discusses the current state of knowledge on the revitalisation of former mining areas, with special regard to architectural, environmental, social, and economic aspects. The aim of the study is to review and promote design solutions which permanently restore previously degraded areas to local communities. Various concepts of revitalisation of degraded areas are presented, based on examples of landscape architecture at home and abroad. The selected examples comprise natural regeneration, reclamation, and ecological engineering. These are examples of a holistic and modern approach to the development of tourist and environmentally active areas in post-mining sites and spoil tips. Furthermore, the study presents the authors' proposal concerning the revitalisation of a spoil tip area at LW Bogdanka mine for winter sport purposes and other activities, for which the demand was signalled by their management. The discussed examples can serve as an inspiration for future actions and executive projects, undertaken in accordance with the guidelines of Agenda 2030 and Fit for 55 policies.

The use of exploited land requires the establishment of reclamation regulations by environment protection bodies, including the partnership of mining supervision authorities. In the case of areas in which natural land relief has been adversely transformed, they are defined by a district chief working in accordance with the legal act [3]. In the case of contaminated land, the extent of necessary activity is then defined by the regional head of environmental protection working in accordance with the legal act [1] (contamination from before 30.04.2007) and legal act [5] (contamination after 30.04.2007). From 2019 to 2023, regarding cases of reclamation, mining supervision authorities cooperated most extensively with district chiefs, issuing on average 1,105 opinions. In 2019 to 2023, 4,982 hectares of land were reclaimed, and 2,368 hectares of reclaimed land were developed. Both the dynamics of reclamation and land development indicate an upward trend, but in 2019 to 2023 a distinct declining' dynamic was observed regarding land handed over to other users.

Airdeck blasting is a promising technique for improved blast efficiency, reducing explosive consumption, and enhancing fragmentation. Nevertheless, it lacks widespread adoption due to design guideline gaps and differing opinions on air deck placement. This study offers technical guidance based on field experiments to optimise air deck blasting. Full-scale blast experiments were conducted at four distinct limestone benches to evaluate the efficacy of air deck implementation. At Bench-1, experiments were performed using conventional blasting (with full-column charge) and air decks at three strategic air deck positions (i.e., top, mid, and bottom) within blast holes at a selected quarry site. For Benches 2 and 3, comparative fragmentation analyses were conducted between conventional blasts and those utilising air decks positioned in the middle of the explosive column. Furthermore, the impact of multiple mid-air decks within explosive columns was also evaluated at Bench-4. A comparison of blast fragmentation results revealed that fragments obtained through the air decking technique surpassed those from the full-column charge, regardless of air deck placement. Among the tested air deck positions, the single air deck positioned at the middle of the explosive column yielded superior fragmentation results than other locations. In addition, this technique showed a reduction in explosive charge, back break, and toe-related issues.

Sulpfur has accompanied us since the dawn of time. Wincenty Kadłubek mentions it for the first time, presenting the legend of the destruction of the Wawel Dragon. According to Dr. A. Wójcik, sulphur could have been one of the reasons for moving the capital from Kraków to Warsaw. The exploitation of this mineral lasted about 500 years. During this time, approximately 700,000 tons of sulphur ore were mined in an area of approximately 5 km, drilling approximately 1,000 shafts and leaving 600 heaps. Following J. Esprinohard, Jan Pazdur quotes a message from 1597 that “when the plague prevails in Kraków, which happens often, most of the citizens leave the city and live for some time near the sulphur mine in Swoszowice and no one is affected by the disease at that time”. Sulphur mining is a niche business, currently as much as 99 percent of this raw material is obtained worldwide in large-scale desulfurization processes of gas, oil and exhaust gases. This was not the case before; sulphur mining in Swoszowice was an important branch of the economy of the Kingdom of Poland and the Austro-Hungarian Empire. Sulphur mining in Swoszowice was finally discontinued over 70 years ago, but it is worth knowing the history of mining in this oldest and longest operating mine in Poland.

Sulphur-bearing limestones encountered in the Mokrzyszów borehole in 1956 sparked the beginning of their exploration, carried out up to 1971 under the guidance of prof. Stanisław Pawłowski, which allowed discovery of about 979 Mt of sulphur resources. Such success was based on combining theoretical studies of sulphur formation in limestone by hydrogen-driven gypsum replacement with geophysical detection of possible sulphur deposit sites. The mining that immediately followed reached a maximum annual production of 4-5 Mt between 1975-1990. The introduction of borehole-based Frasch-type mining provoked many questions regarding sulphur recovery management in relation to the deposit's internal structure. This in turn led to thorough geological study of how mining success depends on the various geological Deposit features. After a decline of mining at the end of the 20th century due to an increased supply of recoverable sulphur from hydrocarbon exploitation, the greater part of the minable resources remain untouched. Many of these became inaccessible for recovery due to the construction of settlements on their territory and strong local opposition to mining. The expected decline in the supply of recoverable sulphur will make those sulphur deposits still accessible for mining a valuable future source, and they merit special protection.

The Arctic region is aprospective areafor ore mining and urbanization progress. The areas of Europe located beyond the Arctic Circle have unique features of the natural environment. Conducting mining works in this place is associated with certain difficulties resulting from weather conditions (numerousrains, long winters, polar night) anddue to the high riskof permanent environmental pollution. An example of the specificity of arctic mining is Kvalsund in northern Norway, where there is a copper mine that is currently under development. Another example is the Monchegorsk region in Russia, which is currently no longer mining. Both of these places are associated with sulphide deposits of non-ferrous metals and the resulting consequences. The purpose of this text was to show the differences and similarities of these mining plants, andon this basis to demonstrate the complexity of the issues of exploitation and reclamation of mining areas in the Arctic.

The cutting tools in mining industry are especially prone to rapid wear, since most of the rocks exhibit aggressive abrasion attributes. A typical representative of fast wearing mining end-tools is a conical pick (also known as tangential-rotary cutter). In order to decrease the premature deterioration, the manufacturers and users tend to enhance the lifespan of the tool by wide range of approaches, namely heat treatment, chemical treatment, burnishing, hard facing etc. In order to estimate the wear rate of a given pick one has to select appropriate procedure and method of evaluation. By this time, most commonly applied method is to estimate the wear rate basing on mass loss measurements of the tools being exploited with constant cutting parameters and fixed conditions. The Authors proposed also a new method of volumetric wear assessment, basing of three-dimensional photogrammetric scanning and compared the results with the outcome of traditional mass wear evaluation of the same sets of tools. Additionally, this paper contains recommendations regarding both approaches (volumetric and mass), especially focusing on the possibilities of the new method concerning measurements of the manufactured tool.

The project presented in the article is proof of the usefulness of student organizations and its effectiveness in the popularization of advanced technologies as well as future solutions in industry. A student-developed planetary rover, using a Kalman filter and other algorithms responsible for dynamic terrain mapping and pathfinding, is capable of non-collision movement in the most challenging environments. Moreover, the rover uses a 6DOF arm developed by students to undertake manual actions, such as soil sampling or maintenance tasks with ease. The invention is provided with a drill to be capable of extracting a sample from a depth of 30 cm, which is expected to greatly enhance the research of the geological history of the surveyed region. The robot has been tested numerous times at planetary rover competitions with success, proving the potential of such platforms as one of starting points in space exploration and opportunities in industrial use, especially in hard-to-reach mining areas. The featured project represents an inspiration for future young engineers and scientists by opening perspectives for implementing similar technologies for more efficient and safer operations in industry.

W artykule zaprezentowano projekt, który stanowi dowód na przydatność organizacji studenckich oraz skuteczność popularyzacji zaawansowanych technologii i rozwiązań w przemysłowej przyszłości. Opracowany przez studentów autonomiczny łazik planetarny, wykorzystując filtr Kalmana oraz pozostałe algorytmy odpowiedzialne między innymi za dynamiczne mapowanie terenu oraz wyznaczanie ścieżek, jest w stanie bezkolizyjne poruszać się nawet w najbardziej wymagających środowiskach. Łazik wykorzystuje również skonstruowane przez studentów ramię 6DOF do swobodnego podejmowania zadań manualnych, takich jak pobieranie próbek gleby czy zadania naprawcze. Jest on także wyposażony w wiertło, które umożliwi pobranie próbki gleby z głębokości co najmniej 30 cm, co mocno wesprze badania historii geologicznej regionu. Robot został wielokrotnie przetestowany z sukcesem na zawodach łazików planetarnych, co potwierdza potencjał takich platform w eksploracji kosmicznej i możliwości zastosowania w przemyśle, szczególnie w trudno dostępnych obszarach górniczych. Prezentowany projekt stanowi inspirację dla przyszłych młodych inżynierów i naukowców, otwierając perspektywy na wykorzystanie podobnych technologii w efektywniejszym i bezpieczniejszym funkcjonowaniu przemysłu.

The project presented in the article is proof of the usefulness of student organizations and its effectiveness in the popularization of advanced technologies as well as future solutions in industry. A student-developed planetary rover, using a Kalman filter and other algorithms responsible for dynamic terrain mapping and pathfinding, is capable of non-collision movement in the most challenging environments. Moreover, the rover uses a 6DOF arm developed by students to undertake manual actions, such as soil sampling or maintenance tasks with ease. The invention is provided with a drill to be capable of extracting a sample from a depth of 30 cm, which is expected to greatly enhance the research of the geological history of the surveyed region. The robot has been tested numerous times at planetary rover competitions with success, proving the potential of such platforms as one of starting points in space exploration and opportunities in industrial use, especially in hard-to-reach mining areas. The featured project represents an inspiration for future young engineers and scientists by opening perspectives for implementing similar technologies for more efficient and safer operations in industry.
