Abstract

In the modern conditions, the scale of subsoil transformation in the process of mineral extraction is characterized by an increased risk of accidents, often accompanied by man-made disasters. In this regard, hazard analysis and accident risk assessment is the most important scientific and technical task, the solution of which is based on methods for identification of hazards, study of development trends and assessment of consequences of theoretically possible accidents. In relation to development conditions of sulfide ore deposits, only an accident risk assessment with determination of the possible accident hazard degree, as well as preparation and timely correction of measures aimed at reduction of accident risks can ensure an acceptable level of industrial safety at the hazardous production facility.

Highlights

Russian mining enterprises with underground mining methods are hazardous production facilities of strategic importance
In Russia, a number of deposits show a stable trend of outbreak and spread of underground fires resulting from sulfide oxidation with self-heating of ores [1]
One of the main reasons for this problem is that in the modern conditions, the industrial safety system at the enterprise is based on statistical data on the number of accidents, incidents and injuries and it does not provide a forecast of development of typical and nontypical scenarios, it does not allow for effective management of industrial safety

Summary

Introduction

Russian mining enterprises with underground mining methods are hazardous production facilities of strategic importance. To prevent spontaneous combustion of pyrite deposits and ignition of sulfide dust, it is necessary not to wait for accidents, incidents and injuries, but to identify existing hazards, assess and rank the risks of initiation and development of hazard scenarios, and take measures aimed at preventing the occurrence of undesirable situations [2]. Relevance of implementing and developing a risk-based approach to ensuring endogenous fire safety at the Russian mining enterprises remains high
