Description
Изобретение относится к горной промышленности и может быть использовано при открытой разработке горизонтальных и пологих пластовых мес- _ торождений полезных ископаемых. *The invention relates to the mining industry and can be used in open pit mining of horizontal and gently sloping reservoir mineral deposits. *
Известен способ открытой разработки горизонтальных и пологих пластовых месторождений полезных ископаемых, включающий отработку вскрышных и до- , бычного уступов полосами [1].There is a method of open development of horizontal and flat formation mineral deposits, including the development of overburden and pre-bull ledges in stripes [1].
Известен также способ открытой „ разработки горизонтальных и пологих пластовых месторождений полезных ископаемых, включающий взаимно перпенди-, кулярное перемещение фронта горных 15 работ на смежных участках.с отработкой передовых, основных и добычных устук-в, внутреннее отвалообразова·^ ние и транспортирование породы конвейерами [2]. 20There is also known a method of open "development of horizontal and gently sloping strata mineral deposits, including mutually perpendicular, moving the front of the mining 15 works in adjacent areas. With the development of advanced, basic and mining rigs, internal dumping and transportation of rock conveyors [ 2]. 20
Однако оба указанных способа характеризуются недостаточной эффективностью разработки.However, both of these methods are characterized by insufficient development efficiency.
Цель изобретения — повышение эффективности разработки. .25The purpose of the invention is to increase the efficiency of development. .25
Поставленная цель достигается тем, что изменение направления подвигания фронта горных работ на передовом уступе и его отвале производят одновременно, при этом фронт отвальных, ра- . 30 бот обеспечивают доработкой основного уступа ступенчатым фронтом в направлении смежного участка.This goal is achieved by the fact that a change in the direction of movement of the front of the mining operations on the forward ledge and its dump produce at the same time, while the front of the dump, ra-. 30 bot provide completion of the main ledge stepped front in the direction of the adjacent section.
На чертеже представлена схема ведения горных работ.The drawing shows a mining scheme.
Способ заключается в следующем.The method is as follows.
Карьерное поле разрабатывают последовательно участками. При переходе с участка 1 на участок 2 изменяют направление подвигания фронта под прямым углом. После окончания работ на передовом уступе участка 1 экскаватор 3 без остановки в работе переводят для отработки передового уступа участка 2. При этом экскаватором 3 производят погрузку горной массы на смонтированный к этому времени конвейер 4, который ранее занимал положение отвального конвейера 5. С помощью конвейеров 4, 6, 7 и 8 горная масса поступает на отвалообразовательThe quarry field is developed sequentially in sections. When moving from section 1 to section 2, the direction of front movement at a right angle is changed. After finishing work on the front ledge of section 1, the excavator 3 without stopping the work is transferred to work out the advanced ledge of section 2. At the same time, the excavator 3 loads the rock mass onto the conveyor 4 mounted by this time, which previously occupied the position of the dump conveyor 5. Using conveyors 4 , 6, 7 and 8, the rock mass enters the spreader
9. Экскаватор 10 во вэаимодёйствии с отвалообразователем 11 продолжает доработку основного уступа ступенчатым фронтом'в направлении участка 2, размещая горную массу во внутренний отвал. Выработанное пространство в торце конечной траншеи служит емкостью для отвала 12 пород передового уступа участка 2.Указанный отвал отсыпают по мере выемки полезного ископаемого экскаватором 13.Отвальный конвейер 14 переносят и используют в качестве забойного 15.9. The excavator 10, in an on-line operation with the spreader 11, continues to refine the main ledge with a stepped front in the direction of section 2, placing the rock mass in the inner dump. The worked out space at the end of the final trench serves as a capacity for the dump 12 of the rocks of the forward ledge of section 2. The dump is indicated as the mine is excavated by the excavator 13. The dump conveyor 14 is transferred and used as a bottomhole 15.
' Данный способ позволит повысить эффективность открытой разработки.'This method will improve the efficiency of open development.
