摘　　要：[目的]探讨模糊数学法在职业病危害控制效果评价工作中的应用,为探索控制效果评价方法提供依据,对职业危害做出更客观、更全面的评价。[方法]采用现场职业卫生调查及检验检测法对某钢铁企业COREX炼铁项目进行职业病危害因素识别与检测,借助模糊数学法进行综合评价。[结果]COREX炼铁项目三个主要生产单元:原料输送单元、炼铁单元、废水处理单元等职业病危害控制水平综合评价为Ⅱ级(良),三个单元整体职业病危害控制效果综合评价也为Ⅱ级(良)。[结论]模糊数学法可综合考虑职业病危害因素的固有危害程度、现场浓(强)度和接触程度,为综合量化职业病危害因素控制水平提供参考。[Objective] The effectiveness of control measures against occupational hazards in a COREX project was comprehensively evaluated using fuzzy mathematics method. [ Methods ] Control measures against occupational hazards in this project were surveyed by the on-site inspection. The level of occupational hazards, including chemical agents, dust and noise, at various workplaces were determined. The fuzzy matrix and weighting coefficient for these hazards was assigned, considering the hazard severity, the concentration or intensity of hazards and the number of workers exposed to hazards in each workplace （evaluation unit）. The total score was calculated to indicate the effectiveness of control measures. [Results ] According to COREX procedures, the workplaces can be divided into 3 characteristic areas （evaluation units）, namely raw material feeding unit,iron smelting unit and wastewater treatment unit. The effectiveness of control measures against occupational hazards in each unit was ranked as Grade 2 （good）. The comprehensive evaluation for whole project was also ranked as grade 2. [ Conclusion ] The fuzzy mathematics model is useful to evaluate comprehensively the effectiveness of control measures, since in this model the multiple factors, such as the characteristics and levels of occupational hazards and the number of exposed workers, were considered in qualitative or quantitative manner.
