For a long time, in the process of mine hoisting system design, the installation position of overwind and overwind protection device is determined according to experience, which is widely disputed, indicating that the system safety has not reached the perfect state, and the traditional experience conclusion needs to be analyzed theoretically. It is necessary to study the parameter matching problem, analyze the impact of overwind protection devices on the system protection results at different installation positions, and improve the safety of the prompt system from a system perspective. The research about parameters matching of overwinding safety protection system of the shaft multi-rope hoisting system has been worked on in this essay by carrying out simulation analysis with numerical methods, involved with specific examples, in the perspective of the dynamics. According to the research, the braking force on the over wind side is significantly greater than that on the under wind side, there is the best matching relation between overwinding and underwinding braking force, making the braking stroke on the overwinding and underwinding side equal, or the overwinding is slightly larger than the underwinding stroke, which will be more beneficial to the safety of the system. The conclusion of this study is helpful to perfect the theory of overwind protection and improve the security of the system.
