Quantitative risk assessment on large-scale oil depots of opencast coal mine
Abstract
In recent years, there are many large-scale oil depots have been built in the opencast coal mine in China. In order to prevent and control the major accidents of the opencast mine, it is significant to assess the risk of the large-scale oil depots. This paper is aiming at bring about a quantitative risk assessment (QRA) method to assess the fire risk of opencast coal mine. Firstly, the risk analysis of large-scale oil depots for coal mine were made, the hazardous characters of gasoline and diesel were described and the risk consequences were discussed. And then, it is pointed that pool fire is the best typical and serious consequence, the mathematical model of pool fire was introduced. Furthermore, the quantitative risk assessment (QRA) method was developed to assess the fire risk of the large-scale oil depots. Also, the QRA method was applied to assess the risk of a selected large-scale oil depot in a large opencast coal mine in China based on the QRA software CASSTQRA. For the gasoline tank of 1´104 m3, the death, serious injury and light injury affected radius of a pool fire were 64.75m, 75.66m and 106.86m and the individual risk was acceptable. Finally, some suggestions were proposed to improve the safety of the large-scale oil depots. The study is helpful to the safety management and prevention of major accident of opencast coal mine.References
