田湾核电站厂区最终边坡工程控制爆破施工技术

Implementation Technology of Controlled Blasting for Final Slide-slope Engineering in Tianwan Nuclear Power Plant Area

在田湾核电站厂区最终边坡工程中采用控制爆破施工技术 ,最大限度地减少爆破对最终边坡的影响 ,确保永久边坡的长期稳定和安全。主要介绍露天深孔大梯段预裂爆破、减震爆破、微差爆破、最大一次装药量的控制措施和关系。

The implementation technology of controlled blasting was applied to final slide-slope engineering in Tianwan nuclear power plant area to minimize the blasting impact on final slide-slope, and to ensure the long-term steady and safety of everlasting slide-slope. The relationship between the pre-splitting, vibration reduction, millisecond blasting and the maximum single detonating charge in open deep-hole large stage is introduced.
