Abstract

In order to analyze the reliability of the ultra-long distance relay pumping and filling system in the actual operation of Jisuo Coal Mine, a fault analysis was conducted on the key equipment of the system in conjunction with the filling process. With the filling system failure as the top event, a fault tree model was established with 13 intermediate events and 42 basic events. After qualitative and quantitative analyses of the fault tree model, the structural importance of the basic events was obtained. Based on the established fault tree model, Monte Carlo simulation analysis was conducted to determine the priority order of the importance of the 42 basic event modes. It was found that the crushing subsystem and the mixing subsystem have the greatest impact on the reliability of the filling system, with the most significant mechanical causes being the mixing drum getting stuck or unable to rotate and the drive motor being overloaded. By comparing actual data with calculation results, the accuracy and effectiveness of the analysis were verified.
