Abstract

This work aimed to analyze professional morbidity in the coal industry of Uzbekistan.
The method of data copying from outpatient cards of professional patients and its statistical
processing was used for analysis. The professional morbidity rate in the coal industry was 108
cases per 10 thousand workers and 6.8 times higher than in other industries. At surface coal
mining in the open pit, as compared to underground mining in a coal mine, the number of
cases of first detected occupational diseases was, on average, 2.6 times lower. Thus, the
vibratory disease was most frequently met among workers of open-cast mining in comparison
with underground mining 1.4 times, and professional bronchitis, bronchial asthma and
pneumoconiosis - among workers of underground mining in comparison with open-cast
mining in 2.3 times.Vibration disease is diagnosed among workers of underground mines at
the work experience of 16 years, while among workers engaged in open-cast coal mining - 21
years and more. The analysis of results of medical and labor examination with professional
diseases of coal industry workers showed that among 48.3 ‰ of workers, there were 30.4 ‰
disabilities of Group III and 17.8 ‰ disabilities of Group II. These indicators had differences
depending on the brand of coal mined, so in the mining of brown coal (SiO2-10%), the
disability of professional genesis amounted to Group II 7.5 ‰ and Group III 31.3 ‰, while in
the mining of coal (SiO2-4%) 4.4 times more established Group II disability (73.3 ‰
workers) than Group III - (16.7 ‰). Conclusion: Coal dust of hard and lignite differ in
chemical and physical properties and degree of dispersion, which affects the level of
occupational morbidity and disability of workers.
