APPLICATION OF ROTARY EXCAVATOR WITH OVERBURDEN TRANSPORT, DUMPING AND OIL SHALE EXTRACTION COMPLEXES AT AKTAU DEPOSIT

ABSTRACT In this article, the intentions on application for the first time in the Republic of Uzbekistan of rotary excavator with the complexes of overburden transportation, dumping and oil shale extraction at the deposit ‘Aktau’ are highlighted. The oil shale deposit is located in Navoi region and by geological and mining conditions is favorable for its combined mining with the use of rotary excavator complexes with high productivity with the use of underground mechanized complexes with the possibility of equipping mines with modern intelligent mining equipment that ensures the safety of sinking of mining and capital, preparatory workings and mining faces. The operation of modern continuous mining equipment, such as belt conveyors, overloaders, walk-behind conveyors and introduction of modern systems of visualization and positioning of quarry workers and intra-quarry transport is actual. Analyses with the use of generated electricity as a result of oil shale processing, which is the reason for increasing energy efficiency of production processes in heavy industry, including the operation of quarry equipment directly used in quarries and mines of the Aktau deposit, are given.
