Abstract

Mine hoist disc braking system, by dynamically adjusting the overflow pressure of the electro-hydraulic proportion relief valve, could control the oil pressure of the disc brake to achieve the safety brake of mine hoist equipment. According to the working features of mine hoist brake system, the author combined with the relevant provisions of the Coal Mine Safety Regulations and conducted simulation analysis of the electro-hydraulic proportion relief valve by AMESim software which lays a solid foundation for further research on mine hoist disc braking system.
