(5) СПОСОБ.ОТКРЫТОЙ РАЗРАБОТКИ СБЛИЖЕННЫХ(5) METHOD OF OPEN DEVELOPMENT OF NEAR
ГОРИЗОНТАЛЬНЫХ И ПОЛОГИХ ПЛАСТОВ ПОЛЕЗНЫХ HORIZONTAL AND LOOSE PLATES USEFUL

Изобретение относитс к горной промышленности и используетс при открытой разработке месторождений полезных ископаемых.The invention relates to the mining industry and is used in the open pit mining of mineral deposits.
Известен способ открытой разраббтки сближенных горизонтальных и пологих пластов полезных ископаемых , включающий отработку вскрышного уступа заходками с отсыпкой вскрышных пород в отвал и выемку добычного уступа заходками путем выемки вышележащего пласта, обработки междуПластов и выемки нижележащего пласта и транспортирование полезного ископаемого С1..There is a method of open development of contiguous horizontal and flat mineral layers, including testing of the overburden ledges with dumps of overburden rocks in the dump and excavation of the mining ledge by means of excavations of the overlying layer, processing between the plastics and the underlying layer and transportation of mineral deposits.
Известен также способ открытой разработки сближенных горизонтальных и пологих пластрв полезных ископаемых , включающий разделение карьерного пол на участки, отработку вскрышного уступаЗаходками с отсыпкрй вскрышных пород в ютвал гребн ми вдоль фронта горных работ и отработку добычного уступа заИСКОПАЕМЫХThere is also known a method of opencast development of contiguous horizontal and flat mineral plastrv, which includes dividing the quarry floor into sections, working out the overburden ledge from the overburden rock formations to the ytval ridges and working out the mining escarpment
ходками путем зачистки вышележащего пласта, выемки последнего, отработки междупласть , представленного потенциально плодородными породами, и выемки нижележащего пласта и транспортирование полезного ископаемого . 2. Однако при применении указанных способов в случае наличи в между пластье потенциально плодородных пород последние укладываютс в нижнюю часть отвала и безвозвратно тер ютс . Другим недостатком указанных способов вл етс то, что рекультивационные работы не включены в единый технологический цикл вскрышных, добычйых и отвальных работ. Это приводит к увеличению трудоемкости рекультивации , снижению продуктивности восстанавливаемых земель и уменьшению эффективности разработки в целом.traversing by stripping the overlying stratum, excavating the latter, working out the inter-area represented by potentially fertile rocks, and excavating the underlying stratum and transporting the mineral. 2. However, when using these methods, if potentially fertile rocks are in between the formations, the latter are placed in the lower part of the heap and are irretrievably lost. Another disadvantage of these methods is that reclamation works are not included in a single technological cycle of stripping, mining and dumping works. This leads to an increase in the complexity of reclamation, a decrease in the productivity of the restored lands and a decrease in the efficiency of development as a whole.
