Increase of depth of open pits with projected angles of operating and final slope resulting in the increase of area proportion of operating (working) zone. Scope of transported masses, length of transportation, prices of operating energy and need for bigger quantity of mineral raw materials from poorer layers result in increase of role of the transport in mining, and at the same time, certain types of transport come to the limit of profitable use. These factors and more complex conditions of exploitation in general, request the improvement of existing and production of new transportation means with higher efficiency, reliability, continuance and economical justification.

In efforts to optimize economical parameters of transport, it is necessary to perform an analysis of various types of transport, and to choose the most optimal. With permanent increase of open pit's depth, extent of transporting masses, transport length, price of powering energy and need for bigger quantities of mineral materials, there comes to an increase of transport role which essentially affects the indicators of pit's operation in whole. This work embraces one segment of problem that comes up at transport on open pits. Lately, most of the designs are made with combined schemes of transport with several transport types in one line and mutual transfer of transported masses.

Production processes of truck material loading by dredgers, emits a remarkable noise levels which distort the optimal working conditions of employees, and they have a negative influence to the health in working and living environment. Concerning the evident excessive noise of dredge operations, it is necessary to apply a series of organizational, interdisciplinary measures with tendency to decrease the noisy events on to normatively allowed levels. In this elaborate, we have done an ergonomic optimization of workers' conditions by decrease of noise levels of dredgers' capacities in order to determine the material gradation composition by the system of mining.
