The paper analyzes the operationing conditions of the automobile transport in the open-pit minings. In the process of deepening open-pit minings steadily become more complex conditions of operation of mining dump trucks, which requires improvement of their design. The influence of parameters of mining dump trucks through the parameters of roads and work sites on the amount of the additional stripping in the career are considered. In the paper shows the rational limits of increasing the highway ramps, which are surmounted by mining dump trucks for different open-pit mining. The directions of development of structures of mining dump trucks are presented, based on the requirements from the side of the surface mining. One of the directions is the creation of specialized quarry vehicles, adapted to a large extent to the specific conditions. A complex of specialized vehicles: mining dump trucks with trolley assist and troll-rechargeable mining dump trucks, mining dump trucks with the hybrid power unit, caterpillar mining dump trucks, trolls-the train. The areas of application of the classical mining dump trucks and the proposed specialized are showen.
