Purpose. Analysis of production experience, scientific and technical developments and assessment of the prospects for the application and development of technologies for the construction of vertical shafts in Ukraine in the context of the need to restore the coal mining industry to preserve the energy independence of the state. Methodology. The methods of analysis of the accumulated production experience of shaft sinking in Ukraine, in the post-Soviet space and in the leading mining countries, as well as scientific and technical literature were used. Results. The classification of technologies and methods of vertical shaft sinking is considered and supplemented, technological schemes and equipment used and promising for Ukraine for the construction of shafts by conventional and special methods are analyzed, the production experience of the Donetskshakhtoprokhodka and Spetsshakhtobureniie trusts is generalized from the point of view of applicability in the construction of shafts of block No. 12 of PJSC Shakhtopravlenie Pokrovskoe”. The possibility of using a modified parallel technological scheme of shaft sinking has been substantiated. The prospects of mechanized shaft sinking in Ukraine – by drilling and with the use of shaft-sinking machines – are assessed. The characteristics of the conditions for the construction and operation of shaft lining, the final element of the shaft, as a structure and functional complex are given. Variants of combined lining, including those with the use of fiber-reinforced concrete, are considered. Scientific novelty. The results of the analysis of technological schemes and methods of vertical shafts sinking, accumulated production experience and scientific and technical developments are generalized, trends and prospects for the development of technologies are considered. Practical value. The analysis of technological schemes and methods of sinking vertical shafts was carried out on the basis of domestic and foreign production experience. Key words: vertical shaft, sinking technology, shaft sinking flow chart, drilling and blasting operations, shafts drilling, shaft-sinking machine.

Artificial ground freezing (AGF) is used worldwide for vertical shaft sinking in difficult hydrogeological conditions. The modern tendency is to determine the design parameters of the freezing technique based on numerical simulation. This work is devoted to the numerical simulation of the formation of an ice-soil wall in the soil stratum due to the AGF and shaft sinking under the protection of the wall. For this purpose, a fully coupled thermo-hydro-mechanical model of soil freezing has been developed on the basis of the theory of poromechanics. The developed model considers important features of the freezing process, such as the phase change, pore water migration due to cryogenic suction, frost heave, and consolidation of the soil. The results have shown that the model allows to predict the distribution of ice content, assess stress and strain in the ice-soil wall, and estimate displacement of the excavation wall.

Underground Transportation

With the continuous development of the mining industry, the world’s major mines have gradually entered the intelligent stage. In intelligent underground mines, the operation roads of the underground transportation equipment are very complicated, and the monitoring and control of the underground traffic have become the problems to be solved in the intelligent underground mines. Therefore, on the basis of solving the practical problems of underground mines, the concept paper discusses the possibility of the communication-based train control (CBTC) system being applied to underground mines through the summary and induction of the related literature. As mining engineers, we have proposed the function design for the CBTC system to solve the problems in underground mine rail transportation, but we still need to continue to work hard for the future development of the underground mines. The concept paper serves as a guide to the Tossing out a brick to get a jade gem, and it has implications for the development and the future of underground mine transportation.
