Method of underground leaching of metals can be modified are lost to traditional technology stocks, but the processes of leaching still produced no comprehensive records of natural and anthropogenic factors, so the results of the use of technology does not always live up to their expectations, which prevents the expansion of the boundaries of its application. Therefore, the development of scientific bases and perfection of technology of leaching of metals from ores reveal are the very important task of the mining industry. Research methods include analysis of the theory and practice of industrial metal leaching study of the effectiveness of modernization of existing situation and elaboration of recommendations to increase the scope of this innovative technology. Results. The analysis of the main processes of underground leaching of metals. Describes the experience of the industrial leaching for example, the metal mines of Russia and Kazakhstan. Highlighted the need for combining in-situ leaching of poor and off-balance ores with the traditional exploitation of rich ores and the balance sheet at the present stage of mining. The described method of control of the completeness of leaching by opening the workings. Marked experience in the application of vacuum drainage systems for productive solutions. Detailed methods of forming the compensation space and the intensification of leaching of blast and other ways. Describes the role of hydraulic fracturing of rocks, injection of destroyed rock solid compositions and fine-grained inert materials in the process of irrigation ores. Conclusions. The combination of the technologies of the poor and leaching off-balance ore with the traditional exploitation of rich ores and the balance at the stages of mining production comprehensively improves their environmental and economic efficiency by using optimal combining methods of preparation and technological parameters, which will allow in-situ leaching to occupy a priority position in the extraction of ores reveal.</p></abstract><trans-abstract xml:lang="ru"><p>Актуальность. Метод подземного выщелачивания металлов позволяет доработать потерянные для традиционной технологии запасы. Однако процессы выщелачивания производятся без комплексного учета природных и техногенных факторов, в связи с чем результаты использования технологий не всегда оправдывают возлагаемые на них надежды, и это препятствует расширению границ их применения. Поэтому разработка научных основ и совершенствование технологии выщелачивания металлов из вскрываемых руд являются весьма актуальной задачей горного производства. Методы исследования проблемы включают в себя анализ теории и практики промышленного выщелачивания металлов, обоснование эффективности модернизации существующего положения и разработку рекомендаций по увеличению области применения этой прогрессивной технологии. Результаты. Дан анализ основных процессов подземного выщелачивания металлов. Описан опыт промышленного подземного выщелачивания на примере металлических рудников России и Казахстана. Обозначена необходимость комбинирования подземного выщелачивания бедных и забалансовых руд с традиционной отработкой богатых и балансовых руд на современной стадии горного производства. Описан способ контроля полноты выщелачивания путем вскрытия горными выработками. Обозначен опыт применения электровакуумных установок для дренажа продукционных растворов. Детализированы методы формирования компенсационного пространства и интенсификация выщелачивания взрывом и другими способами. Описана роль гидравлического разрыва пород, инъектирования разрушенных пород твердеющими составами и мелкозернистых инертных материалов в процессе орошения руд. Выводы. Комбинирование технологий выщелачивания бедных и забалансовых руд с традиционной отработкой богатых и балансовых руд на стадиях горного производства комплексно повышает их эколого-экономическую эффективность при использовании оптимальных для комбинируемых способов подготовки и технологических параметров, что позволит подземному выщелачиванию занять приоритетные позиции при добыче вскрываемых руд.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>металл</kwd><kwd>подземное выщелачивание</kwd><kwd>традиционная отработка</kwd><kwd>подготовка руд</kwd><kwd>горная выработка</kwd><kwd>скважина</kwd><kwd>технология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Metal</kwd><kwd>underground leaching</kwd><kwd>traditional testing</kwd><kwd>ore preparation</kwd><kwd>excavation</kwd><kwd>well</kwd><kwd>technology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Голик В.И., Комащенко В.И., Качурин Н.М.
