Abstract

Abstract: To accurately predict the service life of hydraulic support， the origin and characteristics of the external load of the hydraulic support were analyzed using the interaction relationship between surrounding rock and hydraulic support based on the movement of surrounding rock. Monte Carlo method is used to obtain the load spectrum. The statistics results show that the load amplitude and the load average obey Weibull distribution W(131， 21696) and normal distribution N(1200， 5196)， respectively. Then， the actual load history of hydraulic support at underground was simulated. The work prepares for further research and compiling load spectrum so as to make the life prediction and simulation test indoor.

Key words: hydraulic support, filed wall rock, load history, randomness, Monte Carlo method
