DECARBUST: DECARBONIZATION AND DUST TECHNOLOGIES FOR SUSTAINABLE MINING OPERATIONS V. P Shchokin, V. V Tkachuk Naukovyi Visnyk Natsionalnoho Hirnychoho Universytetu, 2025 Purpose. Scientific justification and experimental confirmation of the effectiveness of the DECARBUST complex decarbonisation and dust suppression technology during mass explosions in quarries using humate reagent in internal and external hydraulic stemming systems. Methodology. The research is based on a comprehensive approach that includes laboratory experiments to determine the sorption properties of the humate reagent, industrial testing of the technology in operating quarries, instrumental measurements of dust and harmful gas concentrations, mathematical modelling of the interaction processes between the humate reagent and dust-gas cloud components, and statistical analysis of the obtained results. Findings. The optimal concentration of humate reagent (3 %) has been established, at which maximum efficiency of harmful gas neutralisation is achieved. A new design of borehole charges with a lateral longitudinal cumulative cavity has been developed, which reduces explosive consumption by 20.8 %. Industrial tests confirmed the technology’s effectiveness: dust emission reduction by 50.5 %, carbon monoxide neutralisation by 61.3 %, and nitrogen oxides by 54.8 %. Originality. For the first time, theoretical foundations of a comprehensive approach to simultaneously addressing dust emission and decarbonisation issues during mass explosions have been developed. The patterns of adsorption processes and chemical neutralisation of harmful gases by humate reagent have been established. A new methodology for calculating the delay of borehole charge initiation has been proposed, considering the preliminary initiation of external hydraulic stemming. Practical value. The DECARBUST technology provides a comprehensive reduction of environmental impact from mass explosions in quarries, meets the requirements of modern climate policy regarding decarbonisation, and has economic advantages compared to traditional dust and gas suppression methods. The technology has been successfully implemented at leading mining enterprises in Ukraine, confirming its practical value and potential for widespread application.
INVESTIGATION OF THE STRESS-STRAIN STATE OF MINE SHAFT SUPPORT UNDER LONG-TERM OPERATION V. P Shchokin, V. V Tkachuk, O. V Aniskov, O. V Kliatskyi Naukovyi Visnyk Natsionalnoho Hirnychoho Universytetu, 2025 Purpose. To develop a methodology for assessing and predicting the stress-strain state of mine shaft support under long-term operation to ensure its long-term stability and safety. Methodology. The research was conducted using an integrated approach that included measurements of the natural pulse electromagnetic field of the Earth (NPEMFE) in the ranges of 2‒7 and 7‒50 kHz, statistical analysis using Pearson’s correlation coefficient and Student’s t-test. The monitoring was carried out at 117 levels of the mine shaft with different measurement steps and the use of three antennas to register signals in different spatial coordinates. Findings. A strong correlation was found between the level number and signal intensity in both frequency ranges (correlation coefficients 0.989 and 0.993), confirmed by statistically significant Student’s t-test results. High-stress zones were identified at levels 70‒90 and 96‒117, where significant increases in signal intensity were observed, indicating potential risks of support deformation. Originality. For the first time, a comprehensive approach to assessing the stress-strain state of a mine shaft using frequency-spatial analysis of NPEMFE signals has been proposed, enabling the detection of not only high-stress zones but also areas of potential water saturation in structures. Practical value. The developed methodology provides non-destructive testing of mine shaft support conditions without drilling operations, reducing operational costs and improving underground safety. The research results enable timely planning of repair works and prevention of emergency situations, ensuring stable operation of mine shafts.

Augmented and Virtual Reality Tools in Training Mining Engineers Viktoriia TKACHUK, Yuliia YECHKALO, Dmytro BROVKO, Wiktoria SOBCZYK Inzynieria Mineralna, 2023 The transition to smart mining has significantly increased the requirements for training modern mining engineers, this necessitating digitalization of this process. Based on scientific research, virtual and augmented reality technology are the most effective and safe. The article presents methods for using virtual and augmented reality technology in training mining engineers. The methods are successfully implemented in laboratories of Kryvyi Rih National University (Ukraine) and have been proven effective during distance learning in the context of the COVID-19 pandemic and the russian military aggression against Ukraine. Nevertheless, further scientific research is needed to introduce modern digital technologies into mining engineers’ training at universities in order to form a competitive and competent specialist.

Such specific computer tools of virtual and augmented reality as pupils’ mobile Internet gadgets can enhance visual character and interactivity of quest problems. The article deals with applying augmented reality in the web environment to solving these tasks. The authors propose a prototype of a career guidance quest system using WebAR technology.
