矿工身心安全的多元联系数影响态势评估

Impact situation assessment of multiple connection number on miners'physical and mental safety

为有效分析深井矿工身心安全态势影响,首先构建矿工身心安全态势影响指标体系,然后采用模糊层次分析(FAHP)和信息熵(IE)法组合赋权得到最终权重,建立基于集对分析的多元联系数影响态势评估模型,判断矿工身心安全的受影响态势及发展趋势,最后将模型应用于河南某高温高湿金矿矿工身心安全影响态势研究中,测定井下3种风速工况、5个温度区间工作环境中矿工的生理、心理、行为变化指标,并采用五元联系数进行影响态势评估。结果表明:高温矿井矿工的自身安全影响发展趋势总体具有同中有反、反中有同,波动前行的特点,是不断变化的;处于反势或均势的指标有臂力、反应力、核心温度、心率,指标反势引致风险态势递增。

In order to effectively analyze impacts on physical and mental safety situation of miners in deep wells,an influence index system of their safety was established.Then,FAHP method and IE method were employed to obtain final weights,and an impact assessment model of multiple connection number based on set pair analysis was developed to identify situations of miners'safety being influenced and its development trend.Finally,the model was applied to a case study in a hot wet gold mine in Henan province,physiological,psychological and behavioral indexes of its miners under three wind speed conditions and five temperature ranges were measured,and five element connection number was used for impact assessment.The results show that the development trend of miners'own safety in high temperature mines is constantly changing,featuring fluctuating forward variance and a mixture of similarity and difference.Indicators of reverse trend or equalizing trend include arm strength,reflexes,core temperature and heart rate,which could lead to an increase of risk degree.
