“…Anthropogenic pollution of the environment has a clear impact on the health of the population [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The steady increase in the release of toxic substances into the environment, primarily affects the health of the population [20][21][22][23][24][25][26][27][28]. In the conditions of mountainous terrain, the problem is even more acute due to the limited and closed space [29][30][31].…”

Two areal spots (Vladikavkaz areal spot and Unal spot) where chemical pollution of soils associated with mining reaches an extremely dangerous level were identified on the territory of North Ossetia-Alania. The areas with varying degrees of environmental stress were identified within the RSO-Alania region based on the obtained data. As a result of eco-geochemical soil sampling in the territory of Vladikavkaz, a technogenic halo of heavy metals dispersion (with an area of about 42 km 2 ) was singled out, the nuclear zone of which, while being characterized by a high concentration of lead, zinc and copper (more than 1%), remains almost unchanged with a significant decrease in the volume of mineral processing in the last decade. Investigations on the influence of negative environmental factors on the morbidity of the population in urbanized areas of Vladikavkaz and Alagir district were conducted. A correlation relationship between the number of neoplasm cases originating from the age group of cancer patients was established. For a more detailed investigation of the distribution of cancer morbidity by age categories, similar data for the Chechen Republic were analyzed.

“…The pollution of the environment in the Republic of North Ossetia-Alania occurs owing to the stationary and mobile sources. Stationary sources include industrial enterprises, which are represented in the republic by such branches as nonferrous metallurgy,machine building and metal processing, electric power industry, fuel industry, timber and wood-working industry, construction materials production [12][13][14][19][20]. The main stationary sources of air emissions are the enterprises of metallurgical industry [15][16][17].…”

Pollution of the environment, besides doing harm to nature, leads to various diseases of the population living in the contaminated area, including cancer diseases. Environmental pollution of the territory of the Republic of North Ossetia-Alania is mainly caused by enterprises of non-ferrous metallurgy and motor transport. Vladikavkaz, the capital of the republic, where the main stationary sources of pollution are located and the number of vehicles is the largest, is exposed to the hardest pollution. In rural areas of the republic, the state of atmospheric air is consistently satisfactory because of the absence of large industrial enterprises in the countryside and a smaller number of motor transports. The material on the population morbidity of malignant growth in various regions of Vladikavkaz was selected. The functional dependence of the patients' percentage on the age group with a high value of approximation reliability was obtained. The main proportion of newly registered malignant neoplasms falls to age groups over 60 years. The analysis of cancer morbidity showed that in the areas of the republic, as well as in Vladikavkaz, where the level of environmental pollution is higher, the rates of cancer morbidity are higher.

Актуальность проблемы комплексного освоения и сохранения недр в настоящее время повышается необходимостью совершенствования основанных на новых принципах технологических процессов, что объясняет необходимость разработки новых и модернизации известных методов управления геодинамическими явлениями в массиве. Объектом исследования являются скальные сложно-структурные месторождения Садонской группы Центрального Кавказа, разработка которых увеличивает напряжения в рудовмещающих массивах с ухудшением качественных показателей использования недр и делает необходимым учет технологических воздействий на массив и меры геомеханического мониторинга его состояния. Целью исследования является обоснование возможности и целесообразности использования продуктов горного и обогатительного передела руд и изготовленных на их основе после извлечения из них полезных компонентов закладочных смесей. Методы достижения поставленной цели исследования включают в себя систематизацию и ранжирование связанных с управлением массивом геологических, технологических и экономических данных, разработку критериев оптимальности и формирование концепции ресурсосберегающей технологии разработки месторождений. Результаты. Детализирована концепция управления геомеханикой рудовмещающих массивов. Дано условие прочности массива на различных стадиях разработки месторождения. Предложена математическая модель взаимодействия переменных факторов. Сформулирован механизм сочетания традиционной технологии с открытым выработанным пространством и новой технологии с выщелачиванием металлов, как в блоках, так и в дезинтеграторах. Даны результаты оценки возможности использования хвостов обогащения в качестве сырья для изготовления твердеющих смесей, полученные в ходе полнофакторных исследований по программам государственных грантов. Даны сведения о гидрохимических способах получения металлов на рудниках. Вмещающим породам Садонских месторождений характерно перераспределение напряжений, в том числе, в геодинамическом режиме. Управление геодинамикой рудовмещающих пород путем регулирования величины напряжений в рудовмещающих массивах требует использования искусственных массивов из хвостов технологических процессов. Показано, что отработка вовлекаемых в производство некондиционных руд и хвостов обогащения запасов и доработка имеющихся запасов по комбинированной схеме может быть рентабельной Relevance of the problem of integrated development and conservation of mineral resources is currently increasing by the need to improve technological processes based on new principles, which explains the need to develop new and modernize well-known methods for managing geodynamic phenomena in the massif. Aim.The object of the study is the rock complex structural deposits of the Sadon group of the Central Caucasus, the development of which increases stresses in ore-bearing massifs with a deterioration in the quality of subsoil use and makes it necessary to take into account technological impacts on the massif and measures of geomechanical monitoring of its condition. The aim of the study is to substantiate the feasibility and advisability of using the products of mining and concentration processing of ores and made on their basis after extracting from them the useful components of filling mixtures. Methods to achieve the research goal include systematization and ranking of geological, technological and economic data related to managing an array of data, development of optimality criteria and the formation of a concept for resource-saving technology for field development. Results. The concept of managing the geomechanics of ore-bearing arrays is detailed. The condition of the array strength at various stages of field development is given. A mathematical model of the interaction of variable factors is proposed. The mechanism of combining traditional technology with open mined space and a new technology with leaching of metals, both in blocks and in disintegrators, is formulated. The results of evaluating the possibility of using enrichment tailings as raw materials for the manufacture of hardening mixtures, obtained in the course of full-factor studies on state grant programs. Information is given on hydrochemical methods for producing metals in mines. The host rocks of the Sadon deposits are characterized by a redistribution of stresses, including in the geodynamic regime. Management of the geodynamics of ore-bearing rocks by regulating the magnitude of stresses in ore-bearing massifs requires the use of artificial arrays from the tailings of technological processes. It is shown that the mining of substandard ores and tailings from the enrichment of reserves involved in the production and the refinement of existing reserves using a combined scheme can be cost-effective
