MODERN STATE AND PROSPECTS OF USAGE OF CYCLIC PROGRESSIVE OPERATION AND PROGRESSIVE OPERATION TECHNOLOGIES FOR OPENCAST MINING AT KRIVBASS DEPOSITS

摘要

Necessity of large-scale putting cyclic progressive operation and progressive operation technologies into practice at Krivbass deposits is substantiated. It allows to rise intensity of the development of deposits owing to concentration of mining operations, to increase productivity, to lower metal capacity and power consumption of the equipment and mining costs owing to usage of mining transportation continuous equipment.
