Abstract

Coal mine hoist charged with transport minerals,materials,ores,personnel important task one of four mines operating in production equipment of particular importance.All-digital DC electric control system for a single rope and coal,multi-mine hoist rope supporting use of DC are introduced.Elevator operation control and drive technology are use of advanced computer control,both with newly installed elevator can also be adapted to elevator control equipment,generators and analog DC control equipment for technological transformation.
