Statistical Analysis of Gas Pipeline Network Accidents in China from 2019 to 2022
摘要
Abstract
169 gas pipeline network accidents publicly reported nationwide from 2019 to 2022 are sor-ted out.The region distribution,month distribution and nominal pipe diameter distribution of accidents,as well as the types and causes of accidents are analyzed.Sug-gestions on preventing gas pipe network accidents are put forward.The results show that the proportion of deaths and injuries in gas pipeline network accidents increased year by year from 2019 to 2021.The propor-tion of deaths and injuries in 2021 was 90.70％and 80.52％,respectively.In 2022,the proportion of deaths and injuries decreased to 0 and 8.61％,respectively.Henan,Jiangsu and Si-chuan are the top three provinces in terms of the num-ber of gas pipeline accidents.Based on the analysis of types of gas pipeline network accidents,leakage ac-counts for the largest proportion at 82.84％.Based on the analysis of accident causes,third-party construction damage accounts for the largest proportion at 61.54％.关键词
