Abstract

The graduation paper is devoted to the development of measures focused on improving the working conditions of the personnel by the dust factor at the Koashva quarry of the Kirov branch of Apatit JSC. The subject of the study is the process of magnetization of aqueous media to provide greater efficiency of dust suppression in open pit mining. As a part of the study, the effect of a permanent magnetic field on the reduction of respirable dust fractions during dust suppression was determined on a self-manufactured laboratory model, and recommendations on the potential industrial implementation of the proposed measures were given. As a part of the risk-based approach, a model for comprehensive risk assessment of pneumoconiosis development was suggested for the open pit mine personnel. The proposed methods to improve the working conditions have shown their effectiveness in terms of the occupational and industrial safety. The conducted risk assessment has allowed to identify the most harmful working zones, which require additional measures to be implemented for provision safe working conditions.
