Abstract: Ensuring the efficient operation of mining machines in the context of a global decline in the quality of the mineral resource base acquires increasing importance affecting the interests of all operations of the technological cycle of obtaining marketable products from a mining and processing enterprise. One of the features of the operation of most mining machines is that the moment of resistance from the side of the executive body changes randomly. The considered option of the controlled electric drive of the mining machine will allow rising the specified life of the mechanical subsystem, maintaining the speed of the working body of the mining machinery in a given area, compensating for the variable component of the load with a dynamic moment, thereby increasing its operational reliability. Due to the fact that the task of speed regulation is ambiguous, an adaptive control algorithm is used to solve it.
