BR28712407 «Development of adaptive technological schemes for reducing soil heaving in mining workings during coal seam extraction based on geodynamic analysis results and three-dimensional modeling data of the surrounding coal-rock mass» – Scientific Supervisor: Mussin Ravil Altavovich
Relevance
The modern development of the mining industry is characterized by a steady trend towards an increase in the depth of mining operations, the complication of mining and geological conditions and an increase in the technogenic load on the rock mass. Under these conditions, the role of geomechanical and gas-dynamic factors that determine the stability of mine workings, the efficiency of degassing and the level of industrial safety increases significantly.
Coal mines operated at depths of more than 600–1000 m are characterized by high rock pressure values, developed rock fracturing, heterogeneity of the stress-strain state and increased gas content of coal seams. These factors cause an increase in the number of manifestations of dynamic phenomena, support deformations, loss of stability of workings, as well as a decrease in the efficiency of traditional technological solutions.
The currently used methods of consolidation, degassing and impact on the massif in many cases were developed for less difficult conditions and do not fully take into account the specifics of deep mining, anisotropy of the properties of the massif and the interaction of technological influences with the natural fracture structure. This leads to the need to search for and scientifically substantiate new or modernized approaches aimed at improving the reliability of mine workings, intensifying gas recovery and reducing the risks of accidents.
In this regard, the development and justification of technologies and methods based on a comprehensive account of the geomechanical state of the rock mass, fracture parameters, gas permeability and the nature of external influences are of particular relevance. The implementation of such approaches makes it possible not only to improve the safety of mining operations, but also to ensure the sustainable and cost-effective operation of deposits in conditions of deep horizons.
Results achieved in the 2nd half of 2025:
In the second half of 2025, the following results were obtained as part of research and applied work:
A comprehensive analysis of geomechanical and gas-dynamic conditions of mine workings in difficult mining and geological conditions was carried out, including an assessment of the stress-strain state of the rock mass and factors affecting the stability of workings and the efficiency of degassing.
Full-scale and laboratory studies of the physical and mechanical properties of rocks and coals, as well as the parameters of fracturing and gas permeability, necessary to substantiate technological and design solutions, were carried out.
Methodological approaches to assessing the state of the massif and selecting the parameters of technological impact, based on a comprehensive account of geomechanical, gas-dynamic and structural characteristics, have been developed and refined.
Experimental work was carried out using specialized equipment and measuring systems that provide reliable data on the state of the massif and the effectiveness of the methods of influence used.
The processing and interpretation of experimental and field data are carried out, generalized dependencies and conclusions are formed that confirm the expediency of using the considered technological solutions in the conditions of deep development.
Materials for scientific publications and reporting documentation were prepared, including analytical sections, graphic materials and justification of the practical significance of the results obtained.
Proposals were formed for the further development of research and the implementation of the results obtained in production practice in order to improve the stability of mine workings and the level of industrial safety.
