摘要
在对一起现场破坏大、物证缺失的天然气爆炸事故的调查认定过程中,通过流体力学公式对天然气泄漏量的测算分析,认定泄漏原因是灶具连接胶管脱落或破裂,并在非爆炸中心找到了点火源,确定了这起点火源与爆炸中心不在同一部位事故的原因。该起事故的调查勘验思路为类似天然气爆炸事故的调查认定提供了参考。
In the course of investigation for an accident of the natural gas explosion whose evidence was missing and scene was destroyed, founded that, the source of leakage is the con- nection hose of cooking utensils fall Off or break, through the formula for calculation and analysis of gas leakage in fluid me- chanics, and ignition sources were found in the non-explosive center. Determined the cause of the accident which the begin- ning of ignition and explosion center is in the different part. The accident investigation had provided reference for similar ac- cident of gas explosion investigation.
