Analysis and Research on Support Reliability of Coal Mine Hydraulic Support
In order to analyse the support reliability of coal mine hydraulic support,a method based on fault tree and failure mode effect analysis(FMEA)is proposed.The method is mainly divided into two stages,the first stage is to establish the fault tree of hydraulic support through fault tree analysis,and then perform Boolean operation to obtain the minimum cut set;the second stage is to obtain the risk coefficient of hydraulic support through failure mode effect analysis.The test results show that this method has certain feasibility and can be used for the support reliability analysis of hydraulic support in coal mine.
