[Incidence of cardiovascular diseases in the workers of deep coal mines]. / Rasprostranennost' serdechno-sosudistykh zabolevanii sredi gornorabochikh glubokikh ugol'nykh shakht.

Examined were 1345 miners working in deep coal mines (temperature 27 degrees C and higher) and non-deep mines (temperature not exceeding 26 degrees C). It was found that increased temperature against the background of other noxious factors of the mine environment and strenuous physical work further the development of diseases of the cardio-vascular system (hypertensive disease, vegetovascular dystonia, ischemic heart disease).

[Incidence of chronic bronchitis in coal miners]. / Rasprostranennost' khronicheskogo bronkhita u gornorabochikh ugol'nylh shakht.

An epidemiological survey of 2000 Donbass coal miners revealed data on the initial dust bronchitis prevalence and its progress. It was established that the coal miners who work in mines with steep coal strata exhibit higher bronchitis morbidity in comparison with the miners engaged in sloping strata mines. A correlation was established between dust bronchitis prevalence and length of professional service and coal miners' labour specificity. Tobacco smokers displayed a markedly higher percentage of chronic dust bronchitis cases.

[Study of the functional status of miners working in deep coal mines based on the results of mass screening]. / Funktsional'noe sostoianie gornorabochikh glubokikh ugol'nykh shakht po rezul'tatam massovogo obsledovaniia.

A clinical survey has been performed of 1640 miners engaged in deep mines characterized by steep geological strata, as a result of which increased disorders have been registered in audio, nervous, cardiovascular and respiratory systems. The maximum shifts of the acoustic analizer were identified in the frequency range of 4000 hertz by 10-12 years and in the speech frequency range by 14 years. Audiologic tests revealed assymmetries in auditory threshold shifts of both right and left ears in all 1640 cases studied.

[Clinico-epidemiologic characteristics of the health status of miners]. / Kliniko-épidemiologicheskaia kharakteristika sostoianiia zdorov'ia gornorabochikh.

Clinico-epidemiological examination of 1944 miners working in mines with sloping layers revealed the incidence of diseases of the main systems of the body. It was found that emotional stresses further the development of primary hypertension in miners with a small length of work. Nonprofessional changes of the hearing organ are evaluated.
