Analysis of Flying Rock for Demolition of Cooling Tower Made by Reinforced Concrete Materials in the Method of FTA

Abstract:

In order to fully prevent flying rocks casting to surrounding constructions in blasting demolition project, fault tree analysis was used for safety evaluation. The analysis and calculation of minimal cut sets and structure importance indicates that the highest probability of flying rock accidents is caused by large quantity of maximum priming charge. And other events come second but cannot be ignored. Thus, several measures were adopted according to the analysis result and the final blasting result showed that no flying accidents happened in the whole process.
