The invention relates to the mining industry and can be used for open development of mineral deposits.

The invention relates to the priority areas of development of science and technology "Technology for environmental security, mining and mining", as it solves one of the problems associated with mechanization and environmental safety of surface mining.

The problem of mechanization and environmental safety surface mining is as follows.

Extraction of minerals by open method is characterized by the cost, the bulk of which are Stripping costs. There are several ways of doing Stripping. Transport technology includes loading the excavator in vehicles, such as dump trucks, and hauling overburden beyond career and their subsequent storage in external dumps [Handbook. Open pit mining. Trubetskoy, K.N. etc., M.: Mining Bureau. 1994, 590 S., str-427]. This technology is the most expensive and has a low productivity. The dusting of roads and release into the atmosphere of the exhaust gases of the engines of trucks pollute the environment.

Bestransportnye technology dragula is new is used when moving overburden outside of the trench and is cheaper and more productive [Dudinskaya F. W., Nechaev K.B. Basic technologies for the development of deep-seated, limited reserves placers in an open way. News of higher educational institutions. Mining journal, 2010, No. 5, 34, 1]. However, the performance decreases with increasing distance moving rocks under repeated their storage and handling. This is due to the limited range of the dragline. This increases the dustiness of the atmosphere due to repeated discharge of rocks from a great height and disturbance of the soil fertile layer.

Bestransportnye practices Stripping within the trench using Stripping units further reduces cost, increases productivity, and improves environmental conditions [Russian Federation patent for the invention №2396394, CL 02F 3/54, AS 47/00, publ. 10.08.2010]. However, the improvement of these indicators is constrained by the fact that the Stripping unit is unable to transport rock from the trench outside to the outer blade in the workflow cycle. This is due to the inability of the passage of the bucket above the upper edge of the ledge on the outside of the blade and the wear of the rope when its friction on the rock of this edge. These deficiencies lead to poor performance, significant wear of the ropes and the deterioration of environmental conditions.

Thus, the problem of perfection the project excavation-transporting complex is to increase its productivity, reduce wear of the rope and the improvement of environmental conditions due to the transportation of overburden rocks outside of the trench to the outside of the blade during the working cycle.
