  • Construction of a physical model of the process of air pollution for cement plants

    The article analyzes the state of urban air. It proved the impact of cement industry on air quality. The article also analyzed the technological process of cement production. As a result, built carrying circuit material flows. Carrying circuit material flows determined that dust is highly polluting air environment, because the dust is released at each stage of production. Analysis of the cement production process has allowed to identify the main objects that are involved in the process of air pollution, as well as to establish their relationship. The result is a physical model of the process of air pollution. Further, on the basis of a physical model of the process of pollution, it is possible to construct a physical model of the process of reduction of air pollution.

    Keywords: the air of the city environment, the process of cement production, carrying circuit material flows, physical model, process air pollution, cement dust

  • The problem of ensuring safety requirements in the construction industry

    The article presents a statistical analysis of non-compliance with safety at work over the past few years, the reasons for violation of safety rules and consequences such as industrial injuries, occupational disease and mortality in the enterprises of the Russian Federation. Based on the analysis, the most dangerous in terms of the safety industry are the companies of the construction industry.

    Keywords: labor protection, safety requirements, the company building industry, industrial injuries, occupational disease, labor protection measures, ability to work, harmful and dangerous production factors
