Purpose. The solution to one of the important problems of the underground mining method is to substantiate cost-effective, technologically feasible and safe variants for mining steeply dipping low-thickness ore bodies. Methods. Mining systems are substantiated on the basis of a detailed analysis of the developed and existing experiential variants for mining steeply dipping ore bodies, identifying production and economic disadvantages, as well as their causes. Findings.As a result of the research, the pillar raise performance in the mining system with ore shrinkage has been substantiated. The main parameters of the proposed variants for mining systems with ore shrinkage, intended for expansion-type supports and borehole breaking, have been substantiated. A design has been developed of fastening the material-running raises (MRR) and ventilating raises (VR) on the working and ventilation horizons to ensure their performance in the mining system with ore shrinkage. Originality. For the first time, dependences of dilution and labour productivity on the ore body thickness and the type of ore breaking for blast-hole stoping and borehole breaking for a single and “twinned block” have been obtained. In addition, a certain dependence of the loading and delivery performance on the average fractional composition, as well as on the delivery distance, has been obtained. Practical implications. The research is characterized by scientific innovations created for the first time, which are able to ensure the efficiency and safety of mining operations, while creating the ability to manage the loss of minerals and dilution in the block, as well as reaching their calculated optimal ratio in order to achieve the most cost-effective production rate.

“…Because of conversion algorithms and geostatic methods, the qualitative data can differ from the actual situation; therefore, methods for improving the conversion algorithms of indicated values are continuously sought. The paper's author is convinced that with the development of the software itself, and also with growing computing capacities of computers, this role will continue to increase (Kaiser et al 2002;Kapageridis 2005;Dyczko 2021b;Kicki et al 2011).…”

“…The solution of this hard complex problem is possible by means of computational experiment methods, since the princi-ple of joint deformation of the weakening mass, rocks in the natural equilibrium arch and in the fastening system has already been used in the calculation by the finite element method [20], [21]. At the same time, the influence of the fastening system characteristic P(u) on the mass deformation-strength characteristic, as well as the influence of P(u) on the behavior of rocks in the natural equilibrium arch are assessed.…”

Purpose. Determination of the rational interaction modes between the fastening system and the extraction working enclosing mass in the zone of stope operations influence. Methods. An algorithm for searching for optimal solutions for the interaction modes between the fastening system and the coal-bearing mass has been substantiated. The deformation-strength characteristics of the fastening system elements have been agreed. The design parameters of the support elements have been optimized according to the criterion of their equal strength. According to the optimal parameters, a methodology for calculating the function that describes the rational deformation-strength characteristic of the fastening system, depending on the mining-geological conditions, has been developed and substantiated. Findings. Computational experiments have been conducted to determine the rock mass deformation-strength characteristic. Based on the normative documents, the sizes of the natural equilibrium arch have been calculated. The adequacy of methodical principles for minimizing the load on the fastening system has been proved. The patterns for the influence of geomechanical factors on the choice of optimal parameters of the fastening system deformation-strength characteristics have been determined. A methodology for calculating the rational parameters of the fastening system and its constituent elements has been obtained. Originality. Combined studies of minimizing the load on the fastening system have been conducted. The patterns for the influence of geomechanical factors on the choice of load-bearing capacity and the yielding property value of the fastening system have been determined. Regression equations have been obtained for calculating the fastening system optimal parameters with a geomechanical index of working conditions. This enables implementation of a unified strategy for resource-saving improvement in fastening systems. Practical implications. A methodology has been developed for obtaining the weakening mass deformation-strength characteristic, depending on the depth of mine working location, the texture of the rocks in the coal-overlaying formation and its strength properties. The applicability of the methodology for the implementation of a unified strategy of resource-saving improvement of the mine working fastening systems for the Western Donbas mines has been proved.
