      <abstract xml:lang="ru">
        <p>Разработка Ошурковского месторождения апатитов традиционными методами с применением буровзрывных работ, а также обогащением добытой руды с использованием флотации и созданием гидротехнических комплексов для хранения мокрых хвостов невозможно, поскольку месторождение расположено в особой экологической зоне Забайкалья, кроме того, для месторождения характерны сложное геологическое строение и низкое содержание полезного компонента в руде. Повышение качества минерального сырья, прежде всего, достигается при его обогащении, однако можно управлять качеством руды уже в процессе ее добычи. Благодаря развитию технических средств повышаются возможности селективной выемки горных пород сложноструктурных месторождений. Целью работы является создание технологии, обеспечивающей повышение качества подаваемого на переработку минерального сырья непосредственно на этапе выемки горной массы. В статье предлагается технологическая схема разработки Ошурковского месторождения с применением выемочно-сортировочного комплекса, включающего транспортно-сортировочный агрегат и контрольно-измерительное устройство для определения содержания полезного компонента в отфрезерованной горной массе, что позволит выделять обогащенную полезным компонентом мелкую фракцию некондиционных руд, которая при использовании традиционных добычных технологий отправлялась бы на склад временно некондиционной руды. Выделение мелких фракций апатитовой руды на транспортно-сортировочном агрегате обеспечит сокращение пыления при ведении добычных работ и снизит потери полезного компонента, связанные с выдуванием мелких фракций при погрузке и транспортировке горной массы. Размещение надрешетного продукта в отрытой траншее с последующей его селективной выемкой погрузчиком позволит выемочно-сортировочному комплексу работать без остановок для замены и ожидания автосамосвалов под погрузку, что обеспечит повышение производительности добычных работ.</p>

        <p>Development of Oshurkovskoye apatite deposit with conventional methods, using drilling, blasting and then processing of extracted ore by means of flotation and construction of hydraulic structures to store wet tailings, turns out to be impossible, as the reservoir is located in a special ecological zone of Transbaikal; moreover, the deposit has a complex geological structure and a low grade of valuable component in the orebody. Refinement of the mineral product occurs primarily during its processing; however, ore grade can already be controlled in the process of its extraction. Advancement of technical facilities opens up new opportunities of selective mining for complex structure deposits. The purpose of this research is to create a technology, which will upgrade the quality of mineral substance, fed to the processing plant, directly at the extraction stage. The paper proposes a technological development scheme for Oshurkovskoye deposit using an excavating-sorting complex containing a transport-sorting facility and a measuring unit for estimation of the grade in a milled rock mass; it allows to separate a rich fine fraction of substandard ore, which under conventional mining practices would have been sent to the stockpile of temporarily substandard ore. Separation of fine fractions of apatite ore in the transport-sorting facility allows to reduce dusting during production and cuts the losses of valuable component, associated with aeration of fine fractions during loading and transportation of the rock mass. Positioning of oversize material in the open trench with its subsequent selective extraction by the loading machine facilitates non-stop operation of the mining-sorting equipment, which provides an increase in the productivity of mining operations.</p>
