Description
Изобретение относитс к горной промышленности и может быть использовано при открытой разработке мульаообраз- . ных месторождений полезных ископаемых с м гкими покрывающими пороаами. The invention relates to the mining industry and can be used in open cast mining. mineral deposits with soft overburden.
Известен способ отработки мульаооб-, разных месторождений полезных ископаемых , включающий выемку вск{Н9ШШых пород горизонтальными сло ми, транспортирование горной массы BQ внешние опвалы и извлечение полезного ископаемого ij .There is a known method of mining multi-mineral and various mineral deposits, which includes excavation of mineral deposits by horizontal layers, transportation of the rock mass BQ external opals and extraction of mineral ij.
Однако данный способ характеризуйетс относительно низкой зффективностьюHowever, this method is characterized by relatively low efficiency.
Известен также способ открытой ра работки месторождений полезных ископаемых уступами, включающий отработку вскрышных пород на наклонной рабочей шсюкости на всю высоту соотве ргвуюшего уступа с последующим отвалообразованием 2J .There is also known a method for open-pit mining of mineral deposits with benches, including the mining of overburden rocks on an inclined working surface to the entire height of the corresponding ledge followed by dumping 2J.
Однако данный способ также недостаточно эффективен в определенных rc vио-геопогических услови х.However, this method is also not sufficiently effective in certain rc vio-geo-geological conditions.
Целью насто щего изобретени вл ет с устранение указанных недостатков.The purpose of the present invention is to remedy these disadvantages.
Поставленна цель достигаетс тем, что уступы с наклонной рабочей плоскостью располагают по торпам карьера, причем уступы перекрывают друг друга по центру карьерного пол , а рабочую Наклонную плоскость каждого нижележащего уступа создают в процессе отработки вышележащего уступа.The goal is achieved by the fact that the ledges with an inclined working plane are located on the torpas of the open pit, with the ledges overlapping each other in the center of the open pit floor, and the working Inclined plane of each lower ledge is created in the process of working the upper ledge.
На чертеже представлена схема, по сн юща предлагаемый способ.The drawing shows a diagram explaining the proposed method.
