Current status of job burnout and its influence on working capability of miners in a copper-nickel mine in Xinjiang Municipality / 中国职业医学

ABSTRACT

OBJECTIVE: To investigate the current status of job burnout and working capability in miners of a copper-nickel mine of Xinjiang Municipality and explore the relationship between miners′ job burnout and working capability.METHODS: A total of 1 254 miners in a copper-nickel mine were selected as study subjects by stratified cluster sampling method. The Chinese Maslach Burnout Inventory and the Work Ability Index Questionnaire were used to investigate their job burnout and working capability.RESULTS: The total score of male miners′ job burnout was higher than that of female miners(P<0.05). The total score of high school educated miners′ job burnout was higher than that of junior middle school and below, junior college, undergraduate and above education groups(P<0.05). The total score of smelting miners′ job burnout was higher than that of mining and ore dressing miners(P<0.05). College degree group, unmarried group, intermediate professional title or above group, monthly income of 4 000-yuan group and mineral processing unit group had higher working capability(P<0.05). Multiple linear regression analysis showed that education level, type of jobs and job burnout level independently affect the miners′ working capability(P<0.01). The miners′ working capability decreased with decreasing education level and the increasing job burnout level(P<0.01). The working capability of ore dressing miners was higher than that of mining and smelting miners(P<0.05). CONCLUSION: The working capability of copper-nickel miners is negatively correlated with their job burnout. Reducing job burnout can improve the working capability of miners.
