The article describes peculiarities and complicating factors when constructing wells in cryolithic zones. It also presents fundamental principles of methods of pilot parametric drilling for complex exploration of engineering-geocryological conditions of multiple-well gas production platforms. The article describes peculiarities of geophysical examinations within the complex of parametric drilling for clarification and correlation of log sheet, and identifying non-commercial gas reservoirs and interpermafrost head oil-filed water horizons in permafrost rock mass. We defined main ecological issues of parametric drilling and presented potential environment pollutants from well drilling in cryolithic zones. It concludes a list of factors, which should be considered during gas well drilling in northern zones for meeting the «safety – sustainability – low waste» criteria.
The article describes the methodological approaches to the expert assessment of the occupational health and safety both in individual enterprises and in the individual territorial units. The advantages and disadvantages of the existing methods of injuries and occupational diseases analysis are represented. In the article a new methodological apparatus, based on the account of sectoral and spatial and territorial factors is offered. The results of the analysis of sectoral and regional distribution of industrial accidents and occupational diseases are represented. The presence of a significant imbalance between the studied parameters in the mining industry: it accounts for 5,9 % of all reported accidents, with 29 % of cases of occupational diseases. For a more accurate assessment of industrial safety expert status provided the use of factors of production troubles the industry and the individual territorial units. It was found that the greatest value of the proposed coefficients correspond to the mining industry and the Kemerovo region.
The negative effects of electromagnetic waves could be appear during violation of the designing established rules of installation and operating various sources of electromagnetic fields. Permanent action of electromagnetic small intensity waves have negatively influence on the enterprise’s workers. Employees feels tired, working capacity can be reduced, there is an un-reasonable irritability, periodic headaches and dream violation. This article is offers a package of measures to reduce electromagnetic load on staff of JSC «Mordovcement», by introduction of electromagnetic shielding system of the industrial frequency fields.
The comparative data on the number of employees at work in hazardous conditions, the structure of the circumstances and conditions of professional diseases are identified causes of unsatisfactory working conditions.
In article the main marks of history of social insurance from operational injuries since the Russian Empire and are stated up to now.
Article represents a historical sketch how there was a formation of principles of safety since the most ancient times up to now. In it is told about formation of legal and social norms in the work sphere for ensuring the right and freedoms working.
In article the possible approach to an assessment of production acceptable risk at level of mining branch or the large enterprise is presented (mine, mine), specifics of which production activity is objectively connected with ineradicable today dangers.
