Purpose. The research purpose is to study the conditions for mining deposits of metamorphic and igneous origin to produce crushed stone products in conditions of limited electricity supply. Methods. The research uses an integrated approach, including data analysis on quarry field spatial dimensions and the overburden rock thickness, which provides the basis for identifying deposits into basic groups. For the identified groups of deposits, taking into account the hydrological characteristics of non-metallic deposits and their parameters, patterns have been determined that characterize the change in the normative atmospheric precipitation inflow, based on the quarry field area and the change in the specific costs for water drainage depending on the studied quarry field type. Based on data on technical characteristics of mobile and semi-stationary units and aggregates, the parameters of physical-mechanical properties of granites and diorites, technical-technological solutions for the formation of complexes for processing raw materials for the production of crushed stone products are proposed. Findings. Problems arising during mining operations under conditions of limited electricity supply, which is caused by mass attacks on Ukraine’s energy infrastructure, have been revealed. A systematization of deposits of igneous and metamorphic origin for mining of rock building materials, which are the basis for the production of crushed stone products, has been developed. The rates of water inflow into the mined-out space depending on the quarry field spatial parameters and the depth of mining operations have been studied. Technological schemes of the apparatuses of a complex for processing raw materials for production of crushed stone products and the apparatuses of a complex for processing siftings are proposed. Originality. Dependences of possible water inflow into the mined-out space of the quarry and change in energy consumption for water drainage have been determined, taking into account the accepted classification criteria, namely the quarry field spatial dimensions, the overburden rock thickness and the quarry depth. Practical implications. The obtained data on the possible water inflow into the mined-out space of the quarry and change in energy consumption for water drainage make it possible to assess the efficiency of pumping units. The proposed technical-technological solutions on formation of complexes for processing raw materials to produce crushed stone products have been developed in accordance with the fundamental provisions of the Law of Ukraine “On approval of the National program for the development of the mineral resource base of Ukraine for the period up to 2030”.

The objective of this research is to improve the efficiency of cold rolling of thin steel sheets with a thickness of 1.5 mm by determining efficient deformation degree. Low-carbon steel 20 was used for the research, and reduction patterns under conditions of cold rolling were determined. While maintaining a constant final sheet thickness of 1.5 mm, the deformation degree was observed to vary based on the initial thickness of the semi-finished rolled product. Key parameters, such as the initial temperature and rolling speed, were adjusted at 200°C and 1 m/s, respectively. The strip width was maintained as a constant, and a friction coefficient of 0.01 was adopted. The research delved into the deformation zone formed during longitudinal sheet rolling, defining its coefficients and essential parameters. Additionally, factors influencing the quality of the resulting sheet were identified. The research also explored the influence of the deformation degree on metal stress during the cold rolling process of thin sheets. This involved an analysis of yield strength, metal flow, and overall strength. Furthermore, the study established the rolling force and its variations with changing deformation degrees. An integral aspect of the study was the examination of the impact of the deformation degree on the process productivity of cold-rolled thin sheets. Through comprehensive analysis, a rational deformation degree was pinpointed, ensuring the production of a high-quality product with efficient strength and plasticity. This optimized degree also minimizes the required deformation forces and rolling torques, contributing to maximum process productivity.
