The authors considered topics of occupational and general comorbidity of occupational lumbosacral radiculopathy in coal miners (2791 examinees) observed over 1976-2014 in occupational center. In patients having lumbosacral radiculopathy without occupational mixed diseases, the occupational disease was diagnosed at the age 3-5 years younger, and 2-4 years earlier from primary visit. Analysis of occurrence of general comorbid conditions with lumbosacral radiculopathy revealed some regularities: patients manifested with symptoms due to vibration have more frequent arterial hypertension than in those with lumbalgia, whereas in risk group of hearing affected by noise IHD was more possible.

The author analyzed dynamics and structure of occupational morbidity including pneumoconiosis in Rostov region of Russian Federation, since 1990 until now. They were compared with analogous parameters of previous historical period. Findings are that contemporary dynamics of anthracosilicosis clinical features is characterized by severily reduced terms of the disease development from medical registration of the diseased miner, earlier addition of malignancy, respiratory failure and other complications--that in aggregate causes earlier disablement and drastically reduced survival rate in occupational patients with anthracosilicosis.

The authors studied vascular endothelium state in coal miners. Findings are lower endothelium-dependent and endothelium-independent vasodilatation, dysbalance of humoral markers--that prove endothelial dysfunction development and remodelling of vascular wall.

Functional shiftwise evaluation of physiologic respiratory parameters was conducted in 166 miners. The conclusion was that each separate occupation has specific requirements.

Shift open-cast development and mining take place in Shubarkul coal deposit situated in semidesert with sharply continental climate. Health state and work capacity of the miners are influenced by climate, occupational and social environmental hazards.

The authors diagnosed dysfunction of autonomous vascular system with affected neuromuscular apparatus, with electrophysiologic polymorphism, degree of nerve trunks disorders in miners having concomitant diseases.

Studies of ABO, Rh, MN, rho, Lewis blood groups in coal miners suffering from anthracosilicosis and in reference healthy individuals proved that MM phenotypes are predisposed to anthracosilicosis and MN phenotypes could be resistant to the disease. These results could be valuable for prevention of this occupational disease among coal industry workers.

The authors analyzed prevalence of individual types of upper limb compression neuropathy in miners of coal and iron-ore mines. Medical examination covered main mining occupations exposed to suchhazards as local vibration, cooling microclimate, functional overstrain. Some types of compression neuropathies appeared to depend on duration of exposure to the hazards and on the occupation hands disease stage.

Work conditions on open-cast minest of Kuzbass include complex of unfavorable natural climate, mining technical occupational factors (microclimate, industrial noise, vibration, aerosols, toxic chemicals, hardiness and intensity of work). According to those occupational factors, the authors calculated risks of morbidity and safe length of service.
