APPROACHES TO RISKS ASSESSMENT DURING POTASH-MAGNESIUM AND ROCK SALTS DEPOSITS EXPLOITATION

Abstract

The key segment which is prepared during hazardous facility safety justification de-velopment is the Assessment of Accident Risk. This article deals with the approaches to the assessment of accidents risks, specific hazards of ore and non-ore mines. The most significant hazards at a mine are rockfalls, rock bursts, ignitions and explosions of flammable gases, fires. Certain types of hazards can be assessed through failure rates, the ventilation system failure, for example, can be calculated on the basis of equipment failure rates, while other types of hazards, the rock bursts, for example, cannot be assessed using the existing (author-ized) methods. It is for that reason that this article reviews a principled approach to the as-sessment of mountain hazards, cites the description of the Factor Method, concerning the potash mines. The methodology cited in the article is the basis for the «Safety technologies» LLC standard «Recommended Practices of Assessment of Accidents Risks at Magnesium Mines» Accident Prevention Company Standard 4.21-2019.
