Abstract:

Objective To clarify the current status of occupational health among migrant workers in the coal mining industry,explore occupational health risk assessment models suitable for migrant workers in the coal mining industry and corresponding risk prevention and control measures. Methods Totally 20 kinds of positions for labor dispatch workers in 15 coal mining industries with normal production in Taiyuan City from November 2018 to December 2024 were selected as the research objects. The occupational hazard risk index method,risk rating table method,semi-quantitative risk assessment comprehensive index method,qualitative risk matrix method,Romania risk assessment method of occupational accidents and diseases(MLSP) were used to assess the occupational health risks of labor dispatch workers in different positions,and the evaluation results were compared. After converting by risk ratio,Kendall correlation analysis was used to compare the correlation of five risk ratios. Results There were significant differences between dispatched workers and regular employees in terms of occupational health examinations and the provision of personal protective equipment. The modified International Council on Mining Metals(ICMM) risk rating method showed strong consistency with the occupational hazard risk index method and the qualitative occupational disease risk assessment method(Kendall method,W=0.875,0.640,both P<0.01),poor consistency with the contact index method(W=0.333,P<0.05),and poor consistency with the qualitative risk matrix method(W=0.100,P>0.05).The occupational health risks of migrant workers in different positions in the coal mine industry were intolerable risks,very high risks,and high risks. Conclusion The occupational health examination for dispatched workers and the provision of personal protective equipment should be uniformly responsible by the employing unit. The modified ICMM semi-quantitative evaluation method and the occupational hazard risk index method demonstrate strong consistency and applicability in assessing the occupational health risks of migrant workers in different positions in the coal mining industry who are exposed to silica dust and coal dust. Qualitative assessment methods are not applicable to risk assessment of migrant workers in different positions in the coal mine industry. Further research is needed to evaluate the scoring of the semi-quantitative contact index method in GBZ/T 298-2017 "Guidelines for occupational health risk assessment of Chemicals in the Workplace".
