FIELD: mining.
SUBSTANCE: invention relates to mining industry and can be used for open selective development of complex structure deposits of solid minerals. Method of selective development of complex-structure deposits of solid minerals involves development of a complex-structural massif by a quarry excavator. To ensure continuous selective excavation without quarrying shovel stop when replacing vehicles, including process of their full loading or in connection with change of type of mined rock, receiving conveyor unloads rock into section bunker, division into sections of which is provided by means of valve controlled by hydraulic cylinder. Type of rock mass taken by a mining excavator is fixed by the control sensors installed on the working body of continuous action and above the receiving conveyor and connected to the automatic control system. In the case of sensors of control of another type of rock mass, the automatic control system sends a signal to close the gate valve, as a result of which the rock mass supplied to the section hopper is in the lower section, and another type of the rock mass is unloaded into the upper section.
EFFECT: technical result consists in improvement of productivity, reliability and technological efficiency of development of complex-structure deposits of solid minerals.
