Fault Analysis and Reliability Research on the Cutting System of Coal Mine Cantilever Tunneling Machine Based on FTA and AHP
The tunneling machine is one of the important equipment for underground tunnel excavation in coal mines.During operation,it faces complex geological structures,poor working environment,and high work intensity.Its cutting part is prone to damage or malfunction during operation.In response to this issue,this article focuses on common faults in the cutting section of tunneling machines,and uses fault tree analysis and analytic hierarchy process as theoretical basis for research.19 basic fault points were identified through fault tree analysis method;Through the Analytic Hierarchy Process,an evaluation system consisting of three intermediate layers and nine determining layers was established,and based on mathematical analysis and calculation,the weights of each factor on the reliability of the cutting part of the tunneling machine were determined.The combination of fault tree and analytic hierarchy process can provide a more objective and scientific way for the fault diagnosis and reliability evaluation of the cutting section of the tunneling machine.
