Description
II
Иаобретение относитс к промышленности и может ть- использовано при открытой разработке пластрвых месторождений полезных ископаемых.The invention relates to industry and can be used in the open cast mining of mineral deposits.
Известен способ разработки пластовых месторождений полезных ископаемых, вклк чающий разделение т ск аЬинсгЬ уступа на подуступы, последовательную поблочную отработку подуступов и ахтвэааго ископаемого и переэкскавацию горной массы во внутренние отвалы fl;).There is a method of developing reservoir deposits of minerals, including the division of the scaffolding of the ledge to the substeps, the sequential block-by-block mining of the substeps and the Achtweaago fossil and re-excavation of the rock mass into the internal dumps fl;).
Известен также способ отк дтой разработки пластовых месторождений полезных ископаемых, включающий разделение вскрышного уступа на подуступы, отработку верхних подуступов с перевалкой горной массы во временный отвал, отработку нижнего подусчупа и попезногб ископаемоего с переэкскавацией породы из временного отвала в посто нный 21.There is also a known method of starting the development of stratum mineral deposits, including the separation of overburden ledge into sub-steppes, working out the upper sub-steppes with transshipment of the rock mass into a temporary dump, working out the lower substep and recovering the rock from the temporary dump into a permanent 21.
Однако оба указанных способа характеризуютс недостаточно высокой эффективностью разработки в определенных горвогеологических услови х.However, both of these methods are characterized by insufficiently high efficiency of development in certain horological and geological conditions.
Целью изобретени вл етс повышение эффективности разработки.The aim of the invention is to increase the efficiency of development.
Поставленна .шлЬ достигаетс тем, что переэкскавацию горной массы верхних подуступов из временного отвала в посто нный осуществл ют до начала OTpa6oivки нижнего подуступа, отработку нижнего подуступа производ т поблочно; в первую .очередь производ т экскавацию части нижнего подуступа, примыкающей к выработанному пространству, с последующей выемкой полезного ископае лого и затем осу;ществл ют зкскавапто оставщейс части нижнего подступа с размещением горной ; массы в выработанном пространстве вскры ваемой заходки.The delivered length is achieved by the fact that the rock mass of the upper sub-steps from the temporary dump into the permanent re-excavation is carried out before the beginning of the lower sub-step OTpa6oiv, the lower sub-step is tested block by block; first of all, a part of the lower sub-accessory adjacent to the developed space is excavated, followed by excavation of mineral resources and then an axis; there are subscapes of the remaining part of the lower approach with the placement of the mountain; masses in the developed space of the opened entry.
Изобретение по сн етс чертежом, на котором представлена схема разработки.The invention is illustrated in the drawing, which shows a design diagram.
Способ заключаетс в следующем. Вскрышной уступ дел т, например, на три прдуступа. При пр мом ходе драглайн отрабатывает верхний подуступ и часть среднего в объеме позиций 1, 2, 3, 4, 5, отСЫП6Ш породу во временный отвал в объемеThe method is as follows. The overburden ledge is divided, for example, into three steps. During the forward run, the dragline works out the upper sub-step and part of the middle in the volume of positions 1, 2, 3, 4, 5, and the rock into the temporary dump in the volume
