Abstract
Способ открытой разработки месторождений полезных ископаемых и призабойный комплекс устройств для его осуществления относятся к горной промышленности и могут быть использованы для открытой разработки месторождений полезных ископаемых в породах различной крепости. Техническая задача - повышение эффективности разработки месторождений полезных ископаемых в породах различной крепости при снижении энергоемкости процессов разрушения и транспортирования горных пород. По способу открытой разработки месторождений полезных ископаемых, включающем буро-взрывное разрушение и отделение от массива вмещающих пород и полезных ископаемых наклонными слоями сверху вниз, перемещение разрушенных пород к основанию уступа под действием силы тяжести, перегрузку и транспортирование, разрушение ведут непрерывно и в поверхностном слое откоса уступа полосами, при этом отделение от массива, перегрузку и транспортирование пород осуществляют синхронно с формированием потока разрушенной породы, причем отделение от массива, перегрузку и транспортирование вмещающих пород и полезных ископаемых осуществляют раздельно. Разрушение включает одновременное бурение и расклинивание полосы породы в заходке из устья шпуров клиньями, причем бурение производят непрерывно и в плоскости, параллельной откосу уступа в направлении от верхней бровки до нижней рабочей площадки уступа. При отработке первой полосы продольные оси крайних шпуров в ряду располагают по линии пересечения боковых сторон отрабатываемой полосы и образуемой плоскости откоса уступа, при переходе к отработке следующих полос пересечение боковой стороны и образуемойThe method of open development of mineral deposits and a bottom-hole complex of devices for its implementation relate to the mining industry and can be used for open-cast mining of mineral deposits in rocks of different strengths. The technical task is to increase the efficiency of the development of mineral deposits in rocks of different strengths while reducing the energy intensity of the processes of destruction and transportation of rocks. According to the method of open-pit mining of mineral deposits, including brown-explosive destruction and separation from the array of host rocks and minerals in oblique layers from top to bottom, the movement of destroyed rocks to the bottom of the ledge under the action of gravity, overload and transportation, destruction lead continuously and in the surface layer of the slope ledge stripes, while the separation from the array, the overload and transportation of rocks carried out synchronously with the formation of the flow of the destroyed rock, and the separation from the masses Islands, transhipment and transportation of the host rocks and minerals are carried out separately. Destruction involves simultaneous drilling and wedging of a strip of rock in a wedge entering from the hole mouth, and drilling is carried out continuously and in a plane parallel to the slope of the ledge in the direction from the upper edge to the lower working platform of the ledge. When developing the first strip, the longitudinal axes of the extreme holes in the row are positioned along the intersection line of the lateral sides of the strip to be worked out and the ledge plane formed during the transition to the next lanes, the intersection of the lateral side and the formed
