摘要
结合水下爆破工程发生盲炮的实例,介绍深水爆破在复杂地质地形、涡流、急流、水深的环境中可能导致盲炮发生的各种潜在危险源。利用系统的观点,分析各种潜在因素的内在联系,建立深水的中深孔盲炮事故树。通过最小割集、结构重要度的分析,求解出各基本原因事件的重要性排序,提出预防盲炮发生的相应措施。由于深水的水压影响,雷管和炸药应具有较好抗水、抗压性能,并事先进行深水性能检测。
According with the examples of the misfire in the underwater blasting, various kinds of potential dangerous which can lead to misfire are introduced in the course of deep water blasting among complicated environment of geological topography, vortex, torrent and deep water. Utilizing the systematic view, analyzing the inner link of different potential factors and the medium-length blasting misfire fault tree will be set up. Through the minimum cut and structure important degree analysis, we can solve out the importance sequencing of every basic reason incident and put forward the corresponding measure of preventing the misfire. The detonator and explosive should be better resist water and resist pressing performance and measured of the deep water performance in advance owe to the influenced of deep water pressure.
