METHOD OF POWER SUPPLY OF MINING MACHINE AND DEVICE FOR IMPLEMENTATION THEREOF Russian patent published in 2024 - IPC B60S5/06 B60L53/10 B60L53/30 B60L53/80 E21F13/08 B60R16/04 

FIELD: machine building.

SUBSTANCE: invention relates to mining machines. In method of mining machine power supply, mobile power plant is delivered to mining machine in underground working and it is installed on mining machine. Control station on mining machine is disconnected from stationary power source and connected to power mobile installation. With the help of a mobile power plant, a mining machine is put into motion and its direct functions are performed. Control station is connected to stationary power source and mobile power plant is transported to charging point. Mobile power plant includes a housing with a cover, with an energy accumulator, a unit of switches, cable inputs and a cable located inside. Outside the housing there installed are sensors: current leakage to earth, insulation monitoring, protection against process overload currents and short-circuit currents. Power transistor modules with control system and programmable logic controller are installed in the housing. On the outer side of the housing there is an operator panel.

EFFECT: accelerated movement and reduced labour intensity.
