基于W-R-SHEL的露天矿山运输系统风险因素研究

Research on Transport System Risk Factors of Open-pit Mine Based on W-R-SHEL

露天矿山运输系统事故原因涉及人、机、环、管等多个环节。基于运输系统复杂、高事故率这一实际情况,以人为因素作为风险因素的分析中心,在总结传统人为风险因素辨识模型存在不足的基础上,提出基于工作分解结构(WBS)与R-SHEL相结合的风险因素辨识模型。将模型具体应用在国内某大型铝土矿山运输系统风险因素研究中,确定5个一级因素指标、13个二级因素指标及40个三级因素指标,采用三级标度IAHP与模糊(fuzzy)相结合的方法实现指标体系中风险因素的综合评判,得出综合评判结果与现场实际情况基本相符。

Personnel,machinery,environment,management and other aspects are related with Open-pit mine transport system accident.According to the fact that Open-pit mine transport system is complex and has high accident rate,human factors are chosen as the focus of risk factors analysis,a new risk factors identification model is proposed based on the combination of WBS and R-SHEL model.With this model,risk factors of a large domestic aluminum mine＇ s transport system were identified,five first-level indexes,thirteen second-level indexes,forty third-level indexes were determined,risk factors＇ comprehensive evaluation was achieved by using three-scale IAHP and fuzzy mathematics,the comprehensive evaluation results are consistent with the practical situation.
