At the present stage of production enhancement it is impossible to create absolutely safe working conditions in the oil production mines of the Yaregskoe field, but ensuring acceptable working conditions in the workplace remains one of the most important tasks in the field of labor protection. Yaregskoe is unique oil field in terms of the shaft method of heavy oil mining. An oil shaft is rather a deviation from the general ideas about the mining industry of Russia and the world. The main idea of the thermoshaft method is a decrease in viscosity and increase in oil mobility due to the heating of a formation by coolant injection. The technology used to extract heavy oil has created special working conditions. The majority of workplaces in oil mines correspond to the 3rd class of working conditions (harmful), degrees 3.1-3.3, where the maximum permissible levels of exposure to harmful factors are exceeded in comparison with permissible values. Harmful working conditions entail a consistently high level of occupational disease. The variety of negative factors and possibility of their combined effects on the body with various combinations of the labor process determine the need for an integrated approach to assess the combined effects of negative factors. Today, the assessment of working conditions is carried out in accordance with the Federal Law of the Russian Federation No. 426-FL "On a special assessment of working conditions" and Order No. 33n of the Ministry of Labor of Russia "On approving the methodology for conducting a special assessment of working condition classifier of harmful and (or) dangerous production factors, the form of a report on the special assessment of working conditions and instructions its filling". In a special assessment of working conditions the overall result is affected only by factors beginning with grades 3 and 4 of working conditions. The combined effect of production and labor process factors is represented only by a qualitative assessment. The analysis performed allowed to rank the probability of the impact of factors of a certain class of working conditions on workers of the Yaregskoe oil mines by structural subdivisions. To assess how labor conditions conform normative labor requirements and a degree of impact of deviations from normal values on human body a special point system (usually a six-point system) is used. There is a calculation of professional risks for the underground staff of the Yaregskoe oil mine made based on the "Point assessment of professional risk". Assessment of occupational diseases shows a high risk of obtaining occupational diseases for a group of underground workers of the Yaregskoe oil mine. There is a special risk for workers at mining and oil production sites. The risk is represented in three parameters such as increased noise, vibration and physical overload. An underground miner and road worker are the safest jobs.
