Risk Assessment of Accidents at Coal Mining Enterprises, Using the Automated System of Calculation of Fault Tree and Event

Abstract

The article deals with the methodological approach to the qualitative and quantitative analysis of the risk of a hazardous production facility, which is regulated by the current legal documentation in Russia. In this case, quantitative methods of failure tree analysis and event tree analysis are highlighted. The article shows possible variants of construction of listed trees for coal mines. The description of the automated system of calculation of trees of failures and events developed in Novokuznetsk Institute (branch) of Kemerovo state University is given. This software product allows you to build these trees with the help of Microsoft Visio, and then calculate the probability of failures and events that caused the accident at each site of the mine and the entire enterprise as a whole and draw up the results of the calculation in the form of a table in automatic mode. Examples of trees construction and results of calculation of probability of occurrence of failures and the events received with use of the described automated system for the concrete enterprise are resulted.
