Abstract
Aiming at the prominent occupational disease hazard problems in metal mining and processing enterprises,a comprehensive evaluation model suitable for multi-factor coupling risks is constructed.Based on the Fuzzy Comprehensive Evaluation Method,the occupational hazard factors were first grouped into a set β={dust,noise,hand-transmitted vibration,high temperature,CO,NO,NO2,SO2,γ radiation},and then weights were calculated through the Analytic Hierarchy Process(AHP).Finally,a fuzzy comprehensive evalua-tion model was constructed by combining fuzzy mathematics theory.An iron ore enterprise was selected as a case study for evaluation.The evaluation results showed that dust(24.1 mg/m3,Level 3),noise(93.5 dB(A),Level 2),and high temperature(34.2℃,Level 2)were high-risk during the screening operation.For waste rock tailings,NO2(4.5 mg/m3,Level 2)and γ radiation(2.7 mSv,Level 2)were classified as medium-risk.The crushing and mineral processing areas exhibited noise(equivalent sound level reaching 107.5 dB(A),Level 1),classified as a severe hazard level.The high temperature and hand-transmitted vibration were in a controllable state.Based on the evaluation results,recommended measures were proposed for different operation areas.This model can quantify the risk levels of occupational hazard factors in metal mining and processing en-terprises,providing a basis for precise prevention and control.关键词
