摘要
Abstract
In the waterway construction project,the construction focus is on the comprehensive regulation of the ob-structed section.At present,underwater drilling and blasting has become the most efficient approach for waterway regula-tion.During underwater drilling and blasting,the influence of water depth should be considered first to determine the suitable explosives and blasting equipment for the project,ensuring the blasting outcomes.Based on the waterway regula-tion project of the Liantuo section between Three Gorges Dam and Gezhouba Dam,the environmental adaptability of detona-tors under deep water conditions was studied,with a specific focus on the impact of water depth on the performance of deto-nators.The results indicate that high-precision plastic nonel detonators and digital detonators are recommended for underwa-ter drilling and blasting construction when the water depth is 0-40 meters.Detonators should be selected according to the actual situation of the project.When the water depth is 50 meters or more,it is recommended to use digital detonators.Because under high pressure and prolonged immersion conditions,the performance degradation of digital detonators is rela-tively small.关键词
