摘要(Abstract):

本文介绍了复杂环境条件下多面临空山体硐室控制松动爆破设计,通过选取合理的爆破参数,正确计算装药量以及采用非电毫秒微差爆破技术,有效地控制了爆破地震波、冲击波、飞石及滚石的危害,确保了周围建筑物的安全,获得了显著的经济效益和社会效益。
This paper introduces a blasting design method of controlled chamber loose blasting of hill body with multiple free surfaces under the complicated circumstances.Inthe design,by optimizing the blasting parameters and calculating the precise charges or adopting the millisecond blasting technology with Nonel Detonator,the harms of blasting vibration,shock wave,flying rock and rolling rock have been effectively controlled and the surrounding buildings have been secured. In the meantime,the remarkable economic benefits and social effects have been obtained.
