Dependencies have been established and methods have been developed to determine the optimum point of stellar mass. Modeling of development of mining operations in conditions of shortage of dump trucks was performed and the area of ??rational location of internal dumps was determined. A new design of the reloading point of road and rail transport has been developed, which does not limit the development of mining operations and allows to reduce the distance of transportation of the rock mass by road. Mining technology has been developed that extends the scope of the circular dump truck by using car lifts to launch empty dump trucks.
