Purpose. Setting of the work environment of workers at mining enterprises during thin coal seams extraction influence on the character and the rate of their aging by determination of the biological age and estimation of the occupational diseases development risk value. Methods. The hygienic estimation of the work environment and the occupational diseases development risk value have been determined according to known standard techniques. The approach developed at the Institute of Herontology of National Academy of Medical Sciences of Ukraine has been used for determination of the miners biological age. The aggregate dust load in the air of mining developments has been determined by “АЕRА” respirator. The follo-wing equipment has been used for estimation of the human functional state: “Nissei DS-1902” and “Omron M10-IT” tonometers, “Maniquick MQ-160” infrared contactless thermometer, “VМ-150” medical balance. Sampling in the miners breathing zone has been made by “АFА-20” analytical filters. The research results processing has been fulfilled by the method of statistical analysis. Findings. The exceeding of the maximum permissible rates of adverse factors for miners, such as dust, noise and vibration has been set. The work environment is featured by the constant uncomfortable position of miners bodies and the sufficient loading level. It is determined, that the maximum risk of occupational diseases development is connected with the dust and the static loading factors. The work in such conditions leads to rising of the miners aging rate. Thus, the aging rate is equal to 7 years while having 28.3 years of average age for less than 10 years of service length, and correspondingly 9 years for more than 10 years of service length. The exceeding of the biological age on the calendar age is 15 years in average after the shift. Originality. The character of interrelation between the complex of harmful factors, the occupational diseases deve-lopment risk and the workers aging rates has been set in the conditions of thin coal seams extraction. Practical implications. It is necessary to change the working and recreation modes of miners and to guarantee the work for not more than 4 hours with obligatory breaks for rest, in order to enhance the life time of the miners occupied at coal-face works on the thin coal seams extraction.
