EFFECT OF MICROCLIMATE ON PERSONNEL IN DEEP-LEVEL EXCAVATIONS OF POTASH MINES

As mining depth grows, the temperature of enclosing rocks increases and the influence of anthropogenic thermal sources on formation of adverse microclimate in mines intensifies. The air temperature in underground working areas exceeds the allowable standard value of + 26°С. As a result, normal sanitary–hygienic labor conditions by the thermal environment criterion become problematic. High air temperature in mines leads to attention deterioration, higher fatigability and, thus, increased occupational traumatism of miners. It is particularly important to evaluate real health status in the heating microclimate. Furthermore, it is required to develop an algorithm of validation of preventive measures to minimize aggravating effect of the mentioned industrial factor in combination with considerable physical load. To this end, it is necessary to accomplish detailed assessment of the thermal environment of mine with a view to determining actual microclimate parameters and workloads. Then, personnel examination should be carried out with measurement of parameters which adequately characterize body thermal status and physiological stress. Later on, the calculations should be performed with interpretation of the obtained results and substantiation of list of engineering controls and hygienic measures aimed at normalization of the thermal environment. The present article authors have developed a model–circuit including all basic stages of investigation.
