Abstract: The function and structure of disk braking system of mine hoisting machine is introduced in the paper, as well as braking requirements, importance of hoisting machine in the system and research status at home and abroad.The influencing factors of disk braking system are analyzed with failure tree, and the research on safety monitoring system technique is made.Combining the failure tree analysis with practical situation, it is concluded that physical quantity being inspected in corresponding situation is obtained and on-line monitoring model is established with modern control method.The monitoring system is developed by industrial control software to achieve on-line data monitoring display, monitoring and alarm of given physical quantity, storage & fetch of important parameter, and search of operating trouble record so as to realize the online monitoring safety of braking system.
