The current working conditions in iron ore mines are characterized by a complex of harmful production factors: noise, vibration and dust, the level of which often exceeds the existing sanitary standards. Under these conditions, workers, especially drillers and tunnellers, have to perform hard, and in some cases, especially hard physical work.

The state of the cardiovascular system and hemodynamics most integrally reflects both the influence of the external environment and the activity of the human body itself [3]. The purpose of this work was to study the features of hemodynamics in drillers and drifters of different seniority groups, to determine the nature and direction of its changes caused by the impact of production factors, and to develop appropriate medical recommendations.

Thus, an increase in blood pressure in drillers and drifters in the dynamics of labor activity occurs due to the increasing peripheral resistance of blood vessels to blood flow.

The vascular type of self-regulation of blood circulation is the least physiologically reliable in comparison with the cardiac and especially the middle type. It most often leads to the development of cardiovascular diseases [1]. For the prevention of hemodynamic disorders in workers of iron ore mines, it is necessary to reduce noise, vibration and dust levels at workplaces, as well as the severity and intensity of labor by mechanizing a number of production processes. It is also important to carry out health-improving measures (water procedures, exposure to a constant magnetic field, electrosleep, etc.).
