Study on Underground Haulage Accident Based onFault Tree Analysis

摘要

Among various accidents except those fatal accidents in coal mine,mostaccidents casualty belongs to haulage accidents.It is one of three major accidentsin coal mine,and constitutes a serious threat to safety production.Taking railhaulage accident in inclined tunnel as an object for study,qualitative analysisand quantitative calculation are made by FTA(Fault Tree Analysis) method ofthe system safety analysis.On the basis of FTA,fault tree for rail haulageaccident in inclined tunnel is built up ,minimum cut sets ,minimum paths sets,and three kinds of importance degree are obtained.By which the accident causecold be found.By aiming at these cause,countermeasure could be taken,and theincidence of the accident could be reduced.
