New approach is proposed to the assessment of the occupational risk conditioned by heating microclimate during mining operations at the oil mines. The topicality of the work is related to the fact that the development of high-viscosity oil deposits by the thermoshaft method is accompanied by the presence in the mine workings of the higher values of the microclimate parameters, as well as the existing shortcomings of the currently used methods for the assessment of the occupational risk at the oil mines caused by the effect of heating microclimate.
The method of occupational risk assessment based on the use of the probit function is substantiated. For this purpose, the analysis of medical and biological studies of the effect of heating microclimate on the human body was carried out. Using the Shapiro-Wilk criterion, checking was conducted related to the hypothesis of the normal distribution of the experimental values of heat accumulation in the human body characterized by a very strong stress of thermal regulation response. As a result, the probit models of the occupational risk assessment were received for the most typical categories of the weight of work at the oil fields of Yaregsky deposit. Verification of such models is given on the basis of comparison with the currently used deterministic model. Mechanism has been also developed that makes it possible to assess occupational risk in the mine workings of oil mines at different velocities of air movement. The possibility of practical application of the chosen approach is shown on the examples of identifying the degree of the required reduction of the Environment Thermal Load (ETL-index) during mining operations in the workings of oil mines achievement of the risk required level.
The advantage of this method is continuous nature of risk distribution, which allows to assess occupational risk more precisely during mining operations. The method is also applicable for the conditions of mine workings with the air velocity of more than 0.6 m/s.
