毫秒延时爆破技术在复杂环境路堑开挖中的应用

Application of Millisecond Delay Blasting Technology in Cutting Excavation with Complicated Surroundings

在滦赤线第一合同段路堑开挖深孔控制爆破工程中,针对其复杂的爆破环境,采用孔内、孔外毫秒延时爆破技术,设计了合理的爆破方案,确保周围设施和建筑物的安全,取得了预想的爆破效果。

In a cutting excavation project for the first contracting section of Luanchuan-Chifeng roadway, a reasonable blasting design is made in the light of complicated surroundings. The anticipated blasting results are obtained by using the in-hole and out-hole millisecond delay blasting technology,thus ensuring the safety of surrounding installations and buildings.
