Quantitative identification and analysis on hazard sources of roof fall accident in coal mine

摘要：

　　The roof fall accident is one of the most frequent accidents in the coal mine and its frequency is ranked the first in various coal mine accidents.Hazard identification is a common method to prevent accidents.On the basis of predecessors research,the concepts and identification indicators of the hazard sources in coal mine roof fall accident are defined initially.Hazard source of roof fall accident is analyzed quantitatively by the method which is combined triangular fuzzy theory and traditional fault tree to avoid the structural problems of the fault tree itself.Large area of empty-support is the greatest hazard sources in roof fall accident by the research.

关键词： hazard source fault tree triangular fuzzy number
