矿井防尘供水管网系统的GO法可靠性分析

为保障煤矿生产的安全运行,采用GO法分析矿井防尘供水管网的可靠性.以双鸭山某矿防尘系统为例,根据其工作原理和结构建立GO图,利用概率公式算法对防尘供水管网系统进行定量和定性的GO运算,获得了系统的状态概率和最小割集.结果表明,比故障树法对同一系统的分析结果更精确.GO方法能够反映系统原貌,非常适合模拟有序列过程的状态系统.对于较复杂的系统,GO法则显得比较简单,优势更加明显.

Reliability analysis of water supply network system for mine dust-proofing in GO methodology

This paper is an effort to analyze the reliability of water supply network for mine dust-proofing by using GO method in order to ensure the safe operation of coal mine. Based on mine dust-proofing system in Shuangyashan City, the paper introduces the production of GO chart on the working principles and structure of mine dust-proof system and the quantitative and qualitative analysis of mine dust-proof network system by using the probability algorithm to obtain the systematic state probability and minimal cut sets. The results show that GO method is more precise than the fault tree analysis method is used to analyze the same system. GO method, capable of reflecting the original condition of system, lends itself better to simulating the system in which the sequential process exists. When used to more complex systems, GO method shows more simplicity and advantages.
