Assessment of morbidity with temporary disability of workers in open pit mining of iron ore

Abstract

Relevance. Morbidity with temporary disability is an important criterion for assessing the impact of working conditions on the workers ' health. The identification of causal relationships of diseases with working conditions of employees gives the possibility to develop preventive measures to prevent disease and improve the health of employees. Aim. To assess the level and structure of morbidity with temporary disability of workers engaged in the mining of iron ore by open way in the modern mining industry. Materials and Methods. To assess the incidence of workers were analyzed sick leave, reports on the causes of temporary disability. For processing the results of the study used mathematical-statistical methods. The Results of the Study and their Discussion. Level STP is 146,90±7.27 cases (p<0,05), 1617,07±66,61 disability days (p<0,05), the average duration of one case constituted of 11,01±0,34, 1,42 times higher than cases and 1,58 times higher for the disability days than workers in the control group Structure STP: first place is occupied by diseases of the respiratory system (58,54 %) of 69,44±1,21 cases (p<0,05), in second place are illnesses of the musculoskeletal system and connective tissue (13,04 %) of 15,51±0.86 cases (p<0,05), in third place injury, poisoning and certain other consequences of external factors (7,92 %) of 9,42±0,13 cases (p<0,05), the fourth place is occupied by diseases of the digestive system (4,56 %) of 5,43±0,19 cases (p<0,05), the fifth place is occupied by diseases of the circulatory system (4,17 %) of 4,96±0,21 cases (p<0,05). Conclusions. The results that can be obtained of the analysis of morbidity with temporary disability of workers of these professions can be regarded as source data and open up prospects for further study of the risks of as the common professional diseases and development of complex of preventive measures aimed at reducing not only diseases with temporary disability, and a pair of professional and occupational pathology. Key Words: open pit mining of iron ore, morbidity with temporary disability.
