某电站右岸坝基975m 高程以下清挖爆破施工技术

摘要

In the dam foundation excavating process on the right bank of a hydropower station, through the improvement of blasting net-work, the safety of the blasting network has been greatly improved, so the large area excavation blasting can be carried in the protection layer excavation process.The application of non electric detonator with special stage can greatly reduce the blasting network detonation time, ensure the safety of blasting network and speed up the construction procedure.%本文主要阐述通过某水电站工程右岸坝基清挖处理过程中，通过爆破网路的改进，大大提高了爆破网路的安全性，可以在保护层开挖过程中，可进行大面积的保护层开挖爆破。采用特殊段别的非电雷管，可以大大减少爆破网路的传爆时间，确保爆破网路的安全，加快了施工进度。
