Introduction. Due to the impact of adverse working conditions and climate, workers in coal-mining enterprises in the Arctic are at increased risk of occupational diseases (OD).The aim of the study was to study the working conditions, causes, structure and prevalence of occupational diseases in miners of coal mines in the Arctic.Materials and methods. Th e data of social and hygienic monitoring “Working conditions and occupational morbidity” of the population of Vorkuta and Chukotka Autonomous District in 2007–2017 are studied.Results. It was established that in 2007–2017 years, 2,296 ODs were diagnosed for the first time in 1851 coal mines, mainly in the drifters, clearing face miners, repairmen and machinists of mining excavating machines. Most often, the ODs occurred when exposed to the severity of labor, fibrogenic aerosols and hand-arm vibration. The development of professional pathology in 98% of cases was due to design flaws of machines and mechanisms, as well as imperfections of workplaces and technological processes. Diseases of the musculoskeletal system (36.2%), respiratory organs (28.9%) and nervous system (22.5%) prevailed in the structure of professional pathology of miners of coal mines. Among the three most common nosological forms of OD were radiculopathy (32.1%), chronic bronchitis (27.7%) and mono-polyneuropathy (15.4%). In 2017, coal miners in the Arctic had a professional morbidity rate of 2.82 times higher than the national rates for coal mining.Conclusions. To preserve the health of miners of coal mining enterprises, technical measures to improve working conditions and medical interventions aimed at increasing the body’s resistance to the effects of harmful production and climatic factors are necessary.

Introduction: Mining in the Arctic is associated with an increased risk of developing occupational diseases. The objective of the study was to investigate the risks, structure and prevalence of occupational diseases in workers engaged in extraction of oil and gas, coal, and ore raw materials in the Russian Arctic. Materials and methods: I analyzed the results of socio-hygienic monitoring “Working Conditions and Occupational Health” conducted in the Arctic zone of the Russian Federation in 2007–2018. Results: Significant differences in working conditions in the extraction of various types of minerals were established, the most favorable being in the oil and gas industry as opposed to the coal mining. The risk of occupational diseases in coal mining was higher than that in oil and gas production (OR = 366.7; CI 275.8–487.6) and ore mining (OR = 1.66; CI 1.58–1.73). Among oil and gas industry workers, the structure of occupational diseases was dominated by sensorineural hearing loss (50.0 %), radiculopathy (20.8 %) and vibration disease (18.9 %). In coal miners, the most prevalent diseases included radiculopathy (32.8 %), chronic bronchitis (26.9 %) and mono-and polyneuropathy (15.5 %), and in ore miners – vibration disease (44.8 %) and radiculopathy (16.3 %). In 2018, compared to 2007, the number of occupational diseases in ore and coal miners increased by 2.16 and 1.42 times, respectively. In 2007–2018, the proportion of occupational diseases diagnosed in miners of the Russian Arctic rose from 57.9 % to 75.6 %. Conclusions: In the mining industry of the Russian Arctic, the maximum health risk is observed in coal mining, and the minimum – in gas and oil industry. The number of occupational diseases in miners tends to increase, which requires improvement of preventive measures adapted to Arctic conditions.

Labor activity in the Arctic, especially mining, is associated with an increased risk of developing occupational pathology. The aim of the study was to investigate working conditions, structure and prevalence of occupational pathology among workers of the Vorkuta industrial region (IR) in 2007–2018. The results of social and hygienic monitoring «Working conditions and occupational morbidity» of the population of the municipal urban district of Vorkuta and the Arctic zone of Russia in 2007–2018 were studied. It was found that in 2007–2018, 99 % of occupational diseases in Vorkuta IR were detected in coal mine workers. Only 1 % of diseases were diagnosed in workers engaged in health care, transport, construction, household services, electricity production and distribution, and industrial production. Over 12 years, the share of increased labor severity in the development of occupational diseases rose from 20.3 % to 74.0 % (p < 0.001), and the share of fibrogenic aerosols decreased from 33.0 % to 13.2 % (p < 0.001). During the same period of time, in the structure of occupational pathology the share of musculoskeletal diseases increased from 20.7 % to 56.9 % (p < 0.001), and the share of respiratory diseases decreased from 31.8 % to 13.4 % (p < 0.001). In 2007–2018, the number of occupational pathology cases tended to grow, and the risk of their development in 2016–2018 was higher than in 2007–2009 (RR = 1.90; CI 1.69–2.12; p < 0.001). The results of the study indicate the need to update programs to improve working conditions and prevent occupational pathology at the Vorkuta coal mines, taking into account the new data obtained.

Introduction. It is known that in industrial workers, working conditions and climatic features of the Arctic create an increased risk of occupational diseases. Th e purpose of the study was to investigate the impact of working conditions on the structure and prevalence of occupational pathology among the working population of the gas and oil producing region in the Arctic.The aim of the study is to explore working conditions, the structure and prevalence of PP in the working population of the gas-oil-producing region in the Arctic.Materials and methods. The data of social and hygienic monitoring in the section “Working conditions and occupational morbidity” of the population of the Nenets and Yamalo-Nenets Autonomous Districts from 2007 to 2017 were studied.Results. It was found that employees in the Arctic gas and oil producing region were most frequently exposed to noise (24.0%), poor microclimate parameters (10.1%), non-ionizing electromagnetic fields and radiation (9.7%). Th e combined effect of several factors was found in 24.8% of workers. Th ere were 285 patients with newly diagnosed OD, 67.0% of whom were air transport workers, and 14.4% were employed in the gas and oil industry. Th e structure of the occupational pathology was dominated by sensorineural hearing loss (77.9%). In 2017, the regional level of occupational morbidity exceeded the national level by 1.7 times, among air transport workers — by 1.9 times, while among employees of gas and oil producing enterprises it was 5.3 times less than the national industry indicator. Th e risk of OD development among air transport workers was higher than in the region as a whole (RR = 45,88; CI 38,3–54,9), in oil and gas companies workers (RR=141,0; CI 100,8–197,2) and in workers of all types of transport, except air transport (RR =68,3; CI 39,8–117,4).Conclusion. In the Arctic gas and oil producing region, most often occupational pathology is recorded among air transport workers, which necessitates the use of a comprehensive program for its prevention. It is necessary to explain the low levels of occupational morbidity in the gas and oil production and other economic activities in the region.

Introduction. The mining and metallurgical industries form the basis of the economy of the Murmansk Region. Working conditions at industrial enterprises, combined with extreme climatic conditions of the Arctic, pose an increased risk of occupational diseases. The purpose of the study was to investigate working conditions and occupational disease rates among industrial workers of the Murmansk Region in 2007–2017. Materials and methods. We studies socio-hygienic monitoring data on working conditions and occupational diseases in the population of the Murmansk Region in 2007-2017 provided by the Federal Center for Hygiene and Epidemiology of the Federal Service for Supervision of Consumer Rights Protection and Human Welfare, Moscow. Results. In 2008-2017, the most common occupational risk factors in the Murmansk Region included noise (25.8%), job strain (17.8%), and chemical factor (12.6%) while 39.2% of workers were exposed to a combination of occupational hazards. Over 10 years, the absolute number of workers exposed to dangerous and hazardous industrial factors decreased by 1.8 times. In the Murmansk Region, 84.3% of occupational disease cases were registered among workers of mining and metallurgical enterprises. In 2007-2017, the region experienced a significant decrease in occupational disease incidence mainly related to job cuts. The role of other factors (improvement of working conditions, health promotion) needs to be clarified; yet, it is possible to predict their positive influence on occupational morbidity in the next few years. Conclusion. To achieve a substantial decrease in occupational disease incidence rates, it is essential to keep improving comprehensive measures aimed at preserving workers’ health in the Murmansk Region.

Mining in the Arctic is associated with an increased risk of developing occupational diseases. The aim of the study was to assess risks of developing occupational pathology over 10-year period of mining apatite ore in the Kola Arctic open-pit mines. We studied data on working conditions (certification of workplaces), health status (periodic medical examinations) and primary occupational pathology (monitoring "Working conditions and occupational morbidity of the population of the Murmansk region" in 2009-2018) of open-pit apatite miners. It was found that, according to an overall assessment, the working conditions of all 436 surveyed open-pit apatite miners corresponded to 3.2-3.3 hazard classes. During 10 years of employment (2009-2018), 88 (20.2%) miners were first diagnosed with 134 occupational diseases, which are 3.07 cases per 100 people per year. The main cause for their occurrence was the severity of work above the permissible level (39.6%), whole-body vibration (37.3%) and noise (17.9%), and their structure is dominated by vibration disease (35.8%) and musculoskeletal pathology (30.0%). The main factor in the occurrence of occupational diseases was recognized as imperfection of technological processes (58.2%). The risk of occupational pathology formation in the excavator drivers (RR=1.95; CI 1.33-2.86; p<0.001) and in the drilling rig drivers (RR=1.60; CI 1.04-2.47; p=0.031) was higher than that of bulldozer drivers. In 2009-2018, unlike the bulldozer and drilling rig drivers, the excavator drivers showed an increased risk of developing occupational diseases (RR=3.50; CI 1.90-6.43; p<0.001). In 2009-2018, the open-pit apatite miners of the Kola Peninsula retained a high level of occupational morbidity, and it tended to increase among excavator drivers.

Introduction. An interest in studying the gender characteristics of occupational pathology is determined by increasing economic activity in the Arctic and the upcoming expansion of women’s access to occupations with harmful working conditions.The purpose of the study was to carry out a comparative investigation of working conditions and occupational pathology among male and female workers at enterprises in the Arctic.Material and methods. The data of socio-hygienic monitoring “Working conditions and occupational morbidity” of the population of the Russian Arctic in 2007-2018 were studied.Results and discussion. 92.6% of occupational diseases have been established to occur in men due to more harmful working conditions (fibrogenic aerosols, noise, whole-body, and hand-arm vibration, the severity of labor). The risk of their occurrence in 2018 was higher than in 2007 (RR = 1.71; CI 1.51-1.93) and higher than in women (RR = 9.45; CI 7.19-12.4). Unlike men, 48.8% of women worked at facilities of the first group of sanitary and epidemiological welfare (satisfactory conditions) and they had in 2007-2018 a relatively stable number of newly diagnosed occupational diseases. The risk of occupational pathology in women in 2018 and 2007 did not change significantly (RR = 1.07; CI 0.73-1.59). In the structure of occupational diseases in men, the first places are occupied by vibration disease (24.2%), sensorineural hearing loss (20.3%) and radiculopathy (20.1%), and in women - myofibrosis of the forearms (21.2%), radiculopathy(13.7%) and chronic bronchitis (13.4%).Conclusion. Reducing exposure to physical overloads, fibrogenic aerosols, noise, vibration, and chemical factors should be a priority preventive direction at enterprises in the Arctic, especially among male workers whose occupational morbidity rate tends to increase.

The Impact

Increasing the maximum speed limit of suspended monorails, which became a very popular means of auxiliary transport, is one of the aspects of improving the efficiency of work in underground coal mines. It is especially important to enable higher (than allowed by the law) travel speed, when moving the crew to and from the workplace, which is often very distant from the shaft, and can take more than one hour of travel. Increasing this speed will make it possible to extend the effective working time of miners, which should have a positive impact on the economics of the mine. However, driving at a higher speed is also associated with increased risk of a negative impact of dynamic overload to people, e.g., during emergency braking of the suspended monorail. The concept of sequential emergency braking was developed in order to avoid excessive deceleration affecting passengers and the operator of the monorail, as well as to minimize the dynamic loads acting on the rail suspensions and on the roadway support frames, which could cause serious accidents. The developed assumptions with regard to the new method of braking are innovative in the area related to hard coal mining, where there are currently no such solutions. According to the principles of the developed concept, the total braking force was divided into two stages. The activation of the second stage depends on the deceleration measured after the time delay from activation of the first stage of braking. We present the results of the numerical simulations, which aimed to analyze the impact of changing the parameters of the braking algorithm on the braking deceleration, the braking time, and the braking distance. The possibility of changing the braking force and downward emergency braking on a high inclination angle were also taken into account during the numerical simulations. Use of the developed emergency braking algorithm enables the optimization of this process at a higher speed than is currently used. This aspect is also very important in increasing the safety for people travelling at a higher speed limit. The numerical simulations provide knowledge for safety in terms of the dynamic overload during emergency braking, without injury risk to miners or damage to equipment.
