        <p>Подземные воды являются одним из ключевых природных ресурсов, поэтому сохранение их высокого качества – основная проблема при добыче полезных ископаемых. Цель статьи – исследование динамики уровенного и гидрохимического режима подземных вод в зоне влияния добычи апатит-нефелиновых руд в юго-восточной части Хибинского щелочного горного массива. За десятилетнюю историю деятельности ГОК «Олений Ручей» АО «Северо-Западная Фосфорная Компания» произошли существенные изменения химического состава исследуемых подземных вод водоносных комплексов верхнечетвертичного осташковского водно-ледникового горизонта f,lgQIIIos и палеозойских интрузий yPz. Содержание главных ионов увеличилось от 2 до 20 раз, нитратов до 50 раз (превышая предельно допустимую концентрацию – 45 мг/л), и NO–3 вошел в разряд главных ионов подземных вод. Источником повышения минерализации и поступления основных ионов в подземные воды являются выветривание и выщелачивание главных рудных минералов – апатита и его разновидностей, нефелина, сульфидных минералов, а также использование взрывчатых веществ, содержащих азотные соединения. В результате гидрохимической эволюции подземных вод изменилось соотношение главных ионов – природная вода гидрокарбонатно-натриевого состава с нейтральными значениями pH в настоящее время стала гидрокарбонатно-кальциевой, на втором месте среди анионов стоят NO–3, среди катионов – Na+. В гидродинамическом режиме подземных вод месторождения Олений Ручей четко выражены весенние и осенние максимумы уровней подземных вод. Во время снижения уровня к скважинам подтягиваются загрязненные более минерализованные рудничные воды, а во время повышения уровня в водоносные горизонты инфильтруются низкоминерализованные воды атмосферных осадков. Установлено снижение среднегодовых уровней подземных вод, что связано с увеличением глубины карьера и водозабором подземных вод для водоснабжения рудника.</p>

        <p>Groundwater is one of the key natural resources, so maintaining its high quality is one of the main problems in mining. The aim of the article is to study the dynamics of the level and hydrochemical regime of groundwater in the influence zone of apatite-nepheline ore mining in the southeastern part of the Khibiny alkaline mountain massif. Over the 10-year history of the Oleniy Ruchey Mining and Processing Plant of North-West Phosphorous Company JSC, significant changes in the chemical composition of the studied groundwater of the aquifers of the Upper Quaternary Ostashkov fluvioglacial horizon f,lgQIIIos and Paleozoic intrusions yPz have occurred. The content of the main ions in groundwater increased from 2 to 20 times, nitrates up to 50 times (exceeding the maximum permissible concentrations of 45 mg/l), and NO–3 entered the category of the main ions of groundwater. The source of the main ions and the increase in mineralization in groundwater is the weathering and leaching of the main ore minerals – apatite and its varieties, nepheline, sulphide minerals, as well as the use of explosives containing nitrogen compounds. As a result of this hydrochemical evolution of groundwater, the ratio of the main ions has changed – natural water of hydrocarbonate-sodium composition with neutral pH values has now become hydrocarbonate-calcium, NO–3 are in the second place among anions, and Na+– among cations. In the hydrodynamic regime of groundwater at the Oleniy Ruchey deposit, spring and autumn maximums of groundwater levels are clearly expressed. During a decrease in the level, contaminated more mineralized mine waters are drawn to the wells, and during an increase in the level, low-mineralized waters of atmospheric precipitation infiltrate into the aquifers. A decrease in average annual groundwater levels has been established, which is associated with an increase in the quarry depth and the water intake of groundwater for water supply to the mine.</p>
