Analysis on epidemiological characteristics of new occupational pneumoconiosis cases of mining and dressing industry of tungsten-molybdenum ore in Ganzhou City from 2006 to 2022
Objective To analyze the new occupational diseases cases in the tungsten molybdenum ore and dressing industry in Ganzhou City from 2006 to 2022,and provide scientific basis for effective prevention and control of occupational diseases.Methods The newly diagnosed occupational pneumoconiosis of mining and dressing industry of tungsten-molybdenum ore in Ganzhou City from 2006 to 2022 were exported from the monitoring information subsystem of occupational diseases and health hazards of China Information System for Disease Control and Prevention.The types,genders,stages,regions,age of initial diagnosis,and years of silica dust exposure of patients with pneumoconiosis were analyzed,and epidemiological descriptions were conducted.Results The newly diagnosed occupational diseases in the mining and processing industry of tungsten and molybdenum mines in Ganzhou were all male silicosis patients,with Chongyi County,Dayu County and Ningdu County having the higher incidence of newly diagnosed occupational pneumoconiosis.The scale of enterprises was mainly small(61 cases),accounting for 50.83％ of the total.Among the occupations,rock drilling workers had the highest incidence of occupational pneumoconiosis,with 22 cases accounting for 18.33％ of the total.The average age of onset of newly diagnosed occupational pneumoconiosis in the tungsten molybdenum mining and selection industry in Ganzhou City was(50.75±5.16)years old,and there was no statistically significant difference in the age of onset of pneumoconiosis among different stages and counties(both P＞0.05).The average length of service was 12.00(7.87,17.50)years,and there was no statistically significant difference in the length of service at different stages of pneumoconiosis incidence(P＞0.05).There was a statistically significant difference in the length of service at the onset of pneumoconiosis among different counties(P＜0.05),with the longest length of service being 28.00(23.00,32.00)years in Yudu County.Conclusion The situation of pneumoconiosis prevention and control in tungsten-molybdenum mining and dressing industry is still serious,and it is necessary to focus on strengthening the occupational disease prevention and control of male silicosis,with Chongyi County,Dayu County and Ningdu County as key counties for prevention and control.We should strengthen the monitoring of occupational hazards and dust and poison control in key industries and positions.
