Purpose. Determination of the noise induced permanent threshold shift for a coal miners in five main working professions, taking into account the noise impact on the way to the workplace and back based on data obtained from personal sound level meters. Methodology. A strategy is selected for measuring the level of noise exposure at workplaces No. 3 per workday (GOST ISO 9612-2016) in a coal mine. Personal sound level meters were attached to the miners shoulders; they measured the noise level on the way to the workplace, during the work shift (8 hours) and on the way back. The processing of the measurement results was carried out on the basis of a quantitative assessment of the noise impact on workers according to the noise induced permanent threshold shift (NIPTS). The NIPTS values were calculated for a period from 3 to 30 years for 5 main professions, taking into account the noise impact when moving to the workplace and back. Findings. The values of the equivalent noise level at miners workplaces of are determined, which are 15 to 20 dBA above the maximum permissible equivalent level (80 dBA). Based on the results obtained, a constant shift in the hearing threshold was forecast for workers of five occupations with seniority of 3 to 30 years. A reduction in the hearing threshold of a sinker will amount to 25 dB in 30 years, which corresponds to the occupational disease Stage 3. Originality. Constant displacement of the hearing threshold for workers in coal mines, caused by the effect of an increased noise level during the journey to the place of work and back, was revealed. Practical value. It was found that in order to prevent the development of an occupational disease (sensorineural hearing loss) in underground miners, it is necessary to measure the noise level by using personal sound level meters for an 8-hour working day, taking into account the way time to the workplace and back. Noise exposure assessment should be based on a continuous decrease in the hearing threshold.
Overview of the modern Russian and International standards in the field of occupational health and safety management at an enterprise is presented. It is determined that the proactive method of assessing the state of working conditions at the enterprise has advantages over the post-event approaches to the development of corrective actions. The assessment is made concerning the application of the generalized Harrington desirability function, which has such properties as continuity, monotonicity, and smoothness. Based on this function, it is possible to assess the state and conditions of occupational safety and compare the indicators of various mining enterprises. GOST 12.0.230.3—2016 was analyzed, and the number of changes were proposed to the method of mathematical calculation. On the example of data provided by the Russian coal industry enterprise, an assessment was made related to the effectiveness and efficiency of the occupational health and safety management system. The values of the linguistic and numerical assessments of the state of the occupational health and safety management system are obtained. Graphic representation of the Harrington function with numerical and linguistic estimates superimposed on it is presented. The applied practices of internal and external audits of the occupational safety management system allow to identify deviations in its work, but they have rather long intervals between checks — from 1 to 3 years. The result of the performed analytical research is an improved methodology for assessment of the effectiveness and efficiency of the occupational safety management system, which allows to make this work more often, easier, and cheaper. Made calculations of the desirability index for a mining enterprise are an example, but they should be carefully analyzed by senior managers for assessment and decision-making. Practical recommendations on the use of the research results by the employer (head of the organization) to improve and develop the system management of occupational health and safety are presented.
The article provides an overview of the main classifications and concepts of human error and human factor in relation to the coal industry. The main issues have been identified, the solution of which will reduce the probability of erroneous actions of the working staff to 70-90%. According to the authors, at the present stage of the development of the coal industry in the Russian Federation, an important issue is the introduction to manning tables of specialists in the study of human factors (ergonomics).Patent analysis of promising systems for controlling harmful production factors based on personal protective equipment for employees has been conducted. The results of theoretical and practical studies in the field of labour protection for the organisation of transparent remote control of workers are presented. Technical solutions are proposed for combining a system for monitoring the use of personal protective equipment (respirator, glasses, headphones) and a protective helmet. The graphical results of an anonymous survey of workers of coal enterprises of the Russian Federation concerning safety and labour protection, as well as the practice of using personal protective equipment, are presented. The results of a survey of employees concerning their attitude towards expanding the functionality of traditional personal protective equipment are summed up.
The article considers the possibility of working with natural and technical systems of the Leningrad region in terms of processing several main types of waste. In article is collection some interesting program product software for waste management. In the process of analyzing the situation with waste management and the involvement of Russian citizens in the methodology of separate collection, the importance of modern software products installed on personal computers and gadgets was emphasized it is the constant interaction with such software products that adapts the methodology of separate collection, allows Russian citizens to learn more about methods of waste treatment, taking care of the environment. In addition, the task was set to create a perfect software product that takes into account the advantages of all previously created software products for recycling waste in the Java Script environment. The author emphasizes the possibility of developing a series of software products for waste management and developing waste management competencies in St. Petersburg residents. It is also worth noting that the created program described in the article is currently being developed in the third version, taking into account more and more information sources on waste processing. It should be noted that the described product contains several built-in hyperlinks to the most significant freely installed products for environmental monitoring. The article contains a separate chapter on the development of legislation in the field of waste management in the Russian Federation in order to reduce spontaneous dumps, and the organization of modernized state-owned enterprises regional operators for waste processing, creating a comfortable economic environment for recycling, rather than storing waste. In the last task, the ECO-365 software product may also be useful for better ecology in all peace.
The article gives reasons for the need to develop the mechanism and tools of performance evaluation based on the implementation of specific management functions, as well as the integrated evaluation of the effectiveness of internal corporate controls. It presents the approbation of the proposed assessment methodology on the example of JSC "SUEK-Kuzbass". The monitoring role as one of the functions of management is constantly increasing in the market economy. The participation of Russian companies in the international economy requires the organisation of internal company control. Moreover, with the enacting of the Law "On Accounting» № 402-FZ, for the majority of economic agents the organising of internal control became mandatory. Thus, the internal control means the process carried out by the Board of Directors and other staff of the organisation aimed at providing reasonable assurance that the objectives of the organisation such as ensuring the effectiveness and efficiency of operations, reliability of financial reporting and compliance with the legislation in force will be achieved.
