510 t级硐室大爆破减震技术

The Technique of Decreasing Vibration of a Chamber Blasting in 510-tone-level Scale

根据硐室爆破实践,提出硐室爆破药室布置型式、排间和排内微差起爆及不偶合装药结构等综合减震技术,解决了多面临空宽厚山体硐室大爆破工程中的减震难题。其震动监测结果表明减震效果良好。这些技术措施和统计分析得到的爆破震动衰减规律可供同类工程借鉴。

The Style of chamber arrargement, millisecond detonation between rows and inner rows and de-couple charge construction to decreasing blasting vibration are mentioned. These techniques resolve cushion problems in chamber blasting engineering in wide thick mountain rocks. The monitoring results of blasting vibration is also introduced. The experiences obtained are useful as a reference for similar engineering.
