煤矿作业人员系统风险知觉能力量化分析

为了定量分析煤矿作业人员风险知觉能力，采用Wickens模型分析风险知觉能力和人因失误作用关系，基于此，结合模糊痕迹理论，提出了基于三角模糊数的信号检测理论，从危险信号辨识敏感性(α)和反应偏好(β)两个指标对煤矿作业人员风险知觉能力进行评价。以某煤矿机电作业人员为例，设计调查问卷，并利用基于三角模糊数的信号检测理论对机电作业人员风险知觉能力进行分析。结果表明，所提出方法可用于评价煤矿井下作业系统中人员的风险知觉能力，能为提升煤矿作业人员风险知觉能力提供参考。

Quantitative analysis on perceptual ability of systematic risk for coal miners

In order to quantitatively analyze the perceptual ability of risk for coal miners, the Wickens model was applied to analyze the relationship between perceptual ability of risk and human error action. Based on this point and combined with fuzzy-trace theory, a signal detection theory based on triangular fuzzy number was put forward, and the perceptual ability of risk for coal miners was evaluated by two parameters including the risk signal identification sensitivity α and the reaction preference β. Taking the electromechanical operation personnel in a coal mine as example, the questionnaire was designed, and the signal detection theory based on triangular fuzzy number was adopted to analyze the perceptual ability of risk for electromechanical operation personnel. The results showed that the proposed method can be used to evaluate the perceptual ability of risk for underground operation personnel in mine, and it can provide reference for improving the perceptual ability of risk for coal miners.
