The modern development of the mining industry is aimed at expanding the development of mineral deposits by surface mining. Along with the increase in the number of surface mining enterprises, a further increase in the extraction of minerals is associated with the development of deeper horizons. At the same time, the cost of transporting rock mass and its cost increase. The growing depth of mining operations places new demands on mining and transportation equipment. The effectiveness of traditional types of open-cut transport – sharply reduced at a depth of more than 150-200 m. The purpose of this research is to develop an electromagnetic vehicle with an automated control system for the delivery of rock mass in large pieces from the lower horizons of the open pit to the surface. The main focus of research is the design and technical capabilities of the locomotive-free conveyor train engine and the development of a combined electromagnetic drive on the basis of electromagnetic motors with a moving magnetic wire and linear asynchronous motors. In order to develop a technical proposal for the creation of a locomotive-free automated vehicle, existing designs and control systems for conveyor trains and electromagnetic motors were studied, as a result of which the positive qualities of solenoid type electromagnets and linear asynchronous motors were established, while it was noted that when they are used together as a combined drive, their drawbacks are almost mutually compensated. The basic idea is to use a hybrid system with electromagnetic drives to move the conveyor train on an inclined track and anelectric unit to control and monitor the interaction of combined electromagnetic drives with the vehicle.
