摘要：Overwinding was the main accident in lifting systems of coal mine and bucket dropping accident was the most serious overwinding accident. According to the cause and mechanism of the bucket dropping accident in main shaft hoisting systems, the conclusion that overloading promotion was the main cause of bucket crash accident was obtained with the fault tree analysis method. One theoretical analysis model was established in order to prevent the occurrence of overloaded bucket dropping accident. The model provided scientific basis and steps in theory for qualitative and quantitative analysis on the cause of falling bucket accident and for the study on accident prediction and prevention. This article proposed several feasible technical measures to prevent the bucket crash accident, which had important guiding significance in practical application. © 2014 IFSA Publishing, S. L.
