摘要

First in the world the stream technology by development of the sloped coal layers had been applied at a cut "Vostochny" in the middle of last century. Cyclic-line technologies (CLT) with conveyer lifting of the crushed rocky ores yet find application on coal cuts of Kazakhstan. For the first time in world practice the curvilinear conveyer lines are approved. First cyclic-line stripping complex with annual production of 10 million m~3 of stripping ores includes two hydraulic excavators R994B and R9350 of LIEBHERR firm with bucket capacity of 18 m~3, 9 auto dump-trucks with load-carrying capacity 90 t of COMATSU firm, double-roll crusher BSW, system of lifting, main and dumping conveyers with width of a belt in 2 m and overburden spreader ARs-B.45.50.
