“…There have been practically no research on hydrogeological peculiarities, namely water inflows into the quarry mined-out space for deposits of igneous and metamorphic origin. This is primarily due to the fact that these quarries are not very deep, currently ranging from 20 to 150 m, and on average no more than 75 m. In works [58]- [60], which studied in detail the issue of groundwater inflow in non-metallic deposits of Ukraine, it is noted that the maximum permissible water inflow during mining the granite quarries is determined by a combination of various factors and, first of all, by the production capacity of the quarry, and should not exceed the value accepted for a large quarry of 2250 m 3 /hour at the production capacity of the enterprise 2500 thousand m 3 /year.…”

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”.

“…Analyzing the situation in Ukraine in this view with further evaluat ion of t h e health quality for the population living in the region, we can establish correlation between human health condition and the quality of the environment. According to medical research, approximately 80% of all diseases of the planet's population are associated with unsatisfactory quality of drinking water and violations of sanitary and hygienic norms of water supply [29][30][31][32][33][34][35].…”

The anthropogenic load on natural environment has reached a level that threatens the population health. The main causes of water sources pollution are the discharge of untreated or insufficiently treated wastewaters by industrial enterprises. These and other reasons lead to the spread of various types of diseases among the population. A cause-and-effect relationship between the qualitative and quantitative state of the surface waters of the Samara River and certain diseases of the population living in the Western Donbas region has been established. The method of statistical analysis based on Pearson correlation has been applied. Reliable correlation between the pollutants content in surface waters of Samara River and the increase of the population diseases in the investigated territory has been proven. With high degree of probability, the following diseases are closely related to water quality: diseases of the blood, hematopoietic organs and disorders of immune system; diseases of endocrine system, digestive and metabolic disorders; circulatory system and digestion diseases; diseases of the skin and subcutaneous tissues. The obtained results indicate the need for further research taking into consideration the regional specificity of conditions and factors of environmental pollution, development of advanced water treatment to reduce the morbidity rate of the population.

“…Water quality is deteriorating due to natural and anthropogenic factors (Chugai and Safranov, 2020). Mine waters of coal enterprises are a large-scale source of pollution of water bodies in the regions (Boyacioglu, 2014;Pavlychenko et al, 2022). They are characterized by increased mineralization, general hardness, the content of suspended substances, sulfates, chlorides, phosphates, fluorides, iron, manganese, copper, petroleum products, and other substances are quite significant due to the intensive discharge of polluted water into water bodies without appropriate treatment (Gavrishin, 2018).…”

Analysis of the scientific and technical literature shows that there are quite a few methods of mine water processing. Reagent methods can be considered as the most promising and economically expedient. Mine waters are characterized by a high content of hardness ions and sulfates. The concentration of sulfates varies between 5-35 mg-eq/ dm 3 , hardness -10-40 mg-eq/dm 3 . It has been established that effective purification of water from sulfates can be achieved with the use of lime and 5/6 aluminum hydroxochloride. The efficiency of the process depends on the doses and ratio of reagents. The degree of softening and purification of water from sulfates increases with an increase in the dose of aluminum coagulant within certain limits. When using 5/6 aluminum hydroxochloride, the efficiency of water purification from sulfates is quite high and small amounts of chlorides are introduced into the water with the coagulant.
