The paper presents the results of hygienic assessment of the working environment and work process factors at surface and underground ore mining operations, ferrous metallurgy plants and aluminum production facilities. It has been established that workers are affected by a complex of production factors (dust, toxic substances, noise, vibration, unfavorable micro climate, etc.), the level of which often exceeds the hygienic standards. The workplace conditions of the primary jobs at these enterprises in 60-80% of cases are classified as hazardous, i.e. Class 3 of various hazard degrees. The incidence of occupational diseases remains high, especially in underground mining and at aluminum production plants. The specific features of mining and metallurgical operations and the severity of unfavorable production factors determine the structure of occupational morbidity. Occupational respiratory diseases are most common among workers in the ferrous metallurgy industry and account for 70.3% in total. Vibration-induced pathologies are most frequently diagnosed among excavator, bulldozer and dump truck operators, and account for 52.9% of all the diagnosed occupational diseases. Hearing organ pathology in the form of neurosensory loss of hearing among workers of mining and metallurgical enterprises ranges from 10.2% (aluminum smelters) to 22.7% (ferrous metallurgy plants) in the occupational morbidity structure. Chronic intoxication with fluorine compounds at aluminum smelters was diagnosed in 68.1% of cases. The results obtained confirm the pressing need to improve the working conditions, introduce preventive measures based on the primary prevention principles, and reduce the risk factors of health problems among the workers.

Metallurgy is exposed to a complex of production factors, the levels of which often exceed the hygienic standards. Working conditions are characterized by grade 3 (harmful) 2-4 degrees, which determine the level of occupational morbidity (PZ). The PP indicator at ferrous metallurgy plants in recent years has fluctuated from 11.9 to 20.2 cases per 10,000 employees that have passed their MEP. In the structure of PZ 59.5% of cases are respiratory diseases. A trend has been established in these enterprises to increase deaths in the workplace, mainly from diseases of the cardiovascular system.

In Russia, in the structure of harmful production factors that cause the development of occupational pathology, the severity of labor takes the second place. The aim of the study was to investigate the effect of increased labor severity on the occurrence, prevalence and structure of occupational diseases in workers at enterprises in the Arctic. The analysis included results of the monitoring study “Working conditions and occupational morbidity” of the population of the Arctic zone of Russia in 2008 – 2018. It was found that in 2008-2018 there was a significant increase in the etiological significance of increased labor severity in the development of occupational pathology: the share of the factor in the total structure of harmful occupational exposures increased from 7.4% to 8.9% (p <0.001), and that of occupational diseases caused by increased labor severity - from 18.6% to 46.9% (p <0.001). Two thirds of occupational diseases caused by the increased severity of labor occur in miners, and diseases of the musculoskeletal system dominate in their structure (80.1%). The risk of developing this group of occupational health disorders in 2018 was higher than in 2008: RR=3,95; CI 3,13-4,99; χ2 =155,9; р<0,001. In contrast to the Russian Federation as a whole, where the increased severity of labor ranks second among the occupational pathology causing factors (24.7%), in the Russian Arctic it came out on top in 2018 (46.9%), exceeding the cumulative effect of all physical factors (44.0%). When carrying out recreational activities and prevention of occupational pathology at enterprises in the Arctic, special attention should be paid to achieving permissible levels of labor severity among workers engaged in mining operations.

Design Guideline

Hydraulic components play a significant role in the mining and construction equipment. It is responsible for smooth change in the output speed, torque, and power of the machine. The hydrostatic drive powered by a constant speed electric motor is widely used in the propel system of the mining equipment. Regulation of the displacements of the pump and the hydro-motor of the drive facilitates the control of the straight running and steering of the machines. In the present scenario, better efficiency and ease of control are the critical aspects to be considered in the design and selection of the hydraulic pump and motor used in underground mining operations. The bent axis hydro-motor is one such equipment that is an electro-hydraulic component that can work in an adverse working environment. The present study deals with the performance analysis of fixed displacement bent axis hydro-motor at different operating parameters such as different temperatures, sizes, viscosity at different loads, and drive speed. For analysis, the hydraulic drive consists of a variable displacement pump rotated by a constant speed electric motor and a fixed displacement hydro-motor. The regulation of the pump displacement controls the speed of the drive. Manually controlled hydrostatic drive propels the said machine against variable load demands. The present work investigates the performances of the hydro-motor used in the mining and construction machine through detailed modeling and experimentations. The steady-state performances are analyzed in terms of slip, torque losses and efficiency of the hydro-motor. The study finds the design guideline to operate the hydrostatic drive using such motors in a reasonable efficiency zone. The model is validated for various operating conditions of the equipment by comparing the predicted results with the test results. The outcome of the present work will be expedient for the preliminary design and assortment of similar hydraulic component used in the mobile, mining equipment.

The problem of industrial injuries and occupational diseases of workers is relevant for all countries, including the Republic of Kazakhstan, where more than 200 people die every year and more than 2,000 are injured at workplaces due to hazardous and harmful production factors, including insufficient natural or artificial illumination of workplaces. The aim of the work is to study the level of illumination of workplaces at enterprises of the Republic of Kazakhstan and to establish the influence of this factor on the working conditions. The object of the study is workplaces and employees of one of the largest machine-building plants, where 60 employees were interviewed, and instrumental measurements of illumination levels were performed in two workshops. The questionnaire method and methods for assessing workplaces by the level of illumination were used. The analysis showed that the largest number of surveyed workers (58.4%) were not satisfied with the level of illumination; according to the instrumental measurements of illumination, 40.9% and 46.6% of workplaces were harmful and dangerous. Employees working under harmful conditions are entitled to a number of benefits and compensations. Thus, the creation of rational working conditions, including illumination of workplaces, helps to minimize injuries and occupational diseases and increase the efficiency and productivity of labor.

The article covers issues related to compulsory state social insurance, which is one of the mechanisms for ensuring health of employees in the course of their work. In his article the author states that accidents and occupational diseases are one of the biggest threats to the health of the working population of Ukraine. The author of the article emphasizes the need to reorient the institution of compulsory state social insurance to strengthen prevention of accidents and occupational diseases, which, accordingly, has lower economic costs than compensation for workers who have suffered any health damage. He also emphasizes the need to finance preventive measures by the Social Insurance Fund, which is not currently implemented. The article emphasizes importance of updating the list of occupational diseases that occur due to occurrence of modern harmful production factors that harm health of the employees. Currently the list of occupational diseases approved by Ukraine is missing the modern production factors related to digital technologies and psychological risks that are the causes of occupational diseases of the employees. The author also states establishment of the same number of social contributions without taking into account working conditions as another shortcoming of the legislation in the field of compulsory social insurance. The author emphasizes the need to establish occupational risk classes, according to which contributions to the compulsory state social insurance should be paid, which will depend on the occurrence of harmful and dangerous factors in the workplace, number of accidents and occupational diseases. In this regard, the author suggests providing a system of motivation of employers, which provides for the possibility of employers to pay lower contributions in connection with creation of favorable working conditions and reduce accidents and occupational diseases.
