Abstract
With the utilization of the deep resources of the earth, it has become a new trend to develop a ultra-deep mine hoist which can meet the conditions of long distance, high speed and heavy load. The research on its braking performance is directly related to the safe operation. This paper is based on a ultra-deep mine hoist simulation test platform. The simulation model of the braking system is established in AMESim software by analyzing the hydraulic working principle. Finally, the field running data of the ultra-deep mine hoist simulation test platform are used to test and verify. The results of simulation and test show that some parameters’ changing rules and impacts such as the greater the spring preloading, the shorter the depressurization time and the response time in the case of no more than a certain value (8.5MPa in this paper). It provides guidance for the research and application of ultra-deep mine hoist brake system in the future.
