Objective: To understand the status of occupational health of Xinjiang coal mine workers and occupational harmful factors in the production process and production process of coal mine enterprises,and analyze and explore the influencing factors of physical and mental health of coal mine workers.Methods: Through stratified cluster sampling method,1500 employees of Xinjiang coal mining enterprises were selected for questionnaire survey,including general demographics,pay-off imbalance questionnaire,SCL-90 mental health questionnaire,and randomly selected 457 workers for occupational health examinations.Understand the occupational health status of coal mine workers,at the same time randomly select a coal mine,identify the occupational harmful factors of coal mines,and conduct sampling and testing according to relevant national laws and regulations to understand the level of occupational harmful factors in underground coal mine production and ground auxiliary systems.Finally,it explores the relationship between operating environment and occupational stress and the mental and physical health of coal miners.Results:(1)General demographic characteristics: This time,a total of 1500 questionnaires were distributed,and 1422 valid questionnaires were recovered,with an effective rate of 94.80%.(2)Occupational stress: gender,education,job type,working age,alcohol consumption,and smoking were different in the ERI group and were statistically significant(P <0.05).Males have higher pay scores than females;unmarried groups have lower overload scores than married and other groups;higher education levels give higher rewards,higher returns,and higher overload scores;mechanical and electrical workers and ventilators pay the highest scores;higher working age pays more points High;the scores of the three dimensions were different in the shift group.The fixed day shift has the highest pay and overload scores,and the four shifts have the highest return scores;(3)Mental health levels: gender,education,job type,working age,shift work,smoking,and drinking have statistically significant differences in the group of mental disorders(P < 0.05).Male workers are more prone to psychological disorders than female workers.The higher the academic qualifications,the higher the possibility of psychological disorders.Ventilators have the highest likelihood of psychological disturbances,and excavators have the lowest probability.The older you are,the more likely you are to have a mental disorder.Smoking and drinking workers are more likely to develop psychological disorders than non-smoking and drinking workers.(4)Physiological health status: The highest detection rate of dyslipidemia(37.92%).The detection rate of dyslipidemia was different among different types of work,working age,shift,smoking,and BMI(P <0.05).The abnormal blood pressure detection rate was different in the types of work,working age,BMI,and ERI(P <0.05).The detection rate of pulmonary dysfunction was different in working age,BMI,dust,and noise groups(P <0.05).Hearing abnormality detection rates differed among types of work,length of service,shifts,noise,and ERI(P <0.05).The abnormal blood glucose detection rate was different in the working age group(P <0.05).There were differences in the grouping of BMI grades in the detection rate of abnormal liver function(P <0.05).(5)Occupational health status in coal mines: Of the 93 sampling points,2 fixed-point dusts failed,1 individual(ventilator)failed,6 fixed-point noises failed,and 1 individual(ventilator)failed.The remaining carbides,sulfides,light intensity,and power frequency electric fields all meet the requirements of national standards.(6)Binary Logistic regression shows that occupational stress increases the risk of abnormal blood pressure,hearing dysfunction,and psychological disorders.Long-term exposure to dust will increase the risk of abnormal lung function,and long-term exposure to excessive noise will increase hearing function and psychological disorders risk.Conclusion:(1)Occupational harmful factors exposed to coal mine workers include dust,carbon monoxide,carbon dioxide,sulfur dioxide,hydrogen sulfide,noise,and powerfrequency electric fields.Of the 93 sampling points in this survey,83 were qualified,with a pass rate of 89.25%.(2)Long-term exposure to occupational harmful factors such as dust and noise will increase the risk of physical abnormalities and psychological disorders.(3)Occupational stress has a significant impact on the mental health of coal mine workers.The higher the level of occupational stress,the more likely it is that psychological disorders will occur.
