Abstract: When transporting overburden and coal at open-pit mining operations, road transport has the greatest importance. In recent decades, the share of its use, especially in Kuzbass, is approaching 90%. There are objective reasons for this, in particular, the deepening of mining operations at open-pit mines, the reduction of the volume of quarries cargo flow and the associated inexpediency of using rail transport. Combined and special methods of transportation are not widely used at open-pit mines, and transportless technology has a rather limited area of application. In this regard, one of the priorities is to optimize the fleet of road transport and its deep modernization on the basis of fundamentally new equipment – unmanned mine dump trucks. At the foreign quarries, this type of equipment still has single cases of application and according to these episodes it is still impossible to make global conclusions about the rationality of application of unmanned dump trucks and about recommendations on their use in specific conditions.
On the basis of the available analysis of classic dump trucks application, the present article attempts to establish the dependence of their productivity change on some influencing factors: the type of rock mass loading and bucket capacity of the excavator used. It is taken into account that when loading an autonomous dump truck, there is no need to maneuver the vehicle, which increases productivity, especially with a small transport distance. Some results of productivity calculation are given, and directions for further research are defined.
