CHARACTERISTIC FEATURES OF TEMPORAL DISABILITY OF COAL-MINERS WITH DISEASES OF BACKBONE AND PERIPHERAL NERVOUS SYSTEM

Abstract

The article adduces the temporal loss of capacity of coal-miners with diseases of backbone and peripheral nervous system. It is determined that the coal-miners of basic professions, working on mines with the steep bedding of coal beds, more often suffer from the diseases of the peripheral nervous system, then those working on mines with the declivous bedding of coal beds. It was observed statistically the meaningful height of temporal disability by reason of illnesses of the peripheral nervous system at experience of work of 6–10 years and more than 20 years.

The aim of the study – to make a link of diseases of the spine and peripheral nervous system of miners of coal mines with working conditions.

Materials and Methods. The task of the stage was to copy data on spine and peripheral nervous system diseases with temporary disability in miners of coal mines and study their structure (professional, age, and length of stay), conduct hygienic assessment of vocational routes of miners suffering from diseases of the spine (lumbar–crudic radiculopathy) elucidation of the possible effect (etiologic diagnosis) of the factors of the working environment and the work process on the morbific person spine and peripheral nervous system among miners of various professional groups. The object of the research: rate of a temporary disability of miners working in mines steep (1188 persons) and flat (1486 persons) layers according to sheets data with temporary disability for 2000–2004 years; protocols of copying data from outpatients miners that were screened in the Regional Clinical Hospital of Occupational Di seases in 2003 (90 persons); employment books data for vocational employment route miners with diseases of the spine and peripheral nervous system (90 persons). When performing work and analysis of materials we used analytical and statistical methods.

Results and Discussion. Morbidity analysis data with temporary disability for 2000–2004 of coal mine workers with flat and steep beds shows that workers of mines with flat seams suffer more and longer (at shallow incidence of 17.5±1.08 disability and 218.5 days for 100 workers, whereas in steep seams – 10.6±0.94 and 139.3 respectively). Miners of productive workings and shaft miners on flat mines and coal hewers and shaft miners on mines with a steep layers bedding suffer from a disease more often. It was established that on the mine with a flat bed bedding the largest percentage in the structure of morbidity with temporary disability take osteochondrosis disease and musculoskeletal system. Diseases of the peripheral nervous system are on the first place in miners of mining steep seams. The interrelation of diseases of the spine and peripheral nervous system of seniority and age was set. In mines with the most gentle layers relationship of diseases with professional experience is closer, and on the mines with steep seams – with age. The data of exposure conditions in different occupational groups on the development of musculoskeletal diseases and peripheral nervous system, age-contacted characteristics, conditions of disease severity were analyzed. The hazard risk for diseases of the musculoskeletal and peripheral nervous systems is most likely in occupations where working conditions are rated 2, 3 and 4 degrees by hygienic third grade classification.

Conclusions. In workers of mines initial forms of musculoskeletal diseases and peripheral systems developed at experience of 4–6 years, and in 12–16 years – chronic (severe). The results allowed to prepare data on the impact of working conditions on the state of the spine and peripheral nervous system of coal miners to be used in further studies.
