摘要
经过现场爆破试验和爆破地震效应观测,采用孔内分段间隔装药、孔内孔间微差爆破方案,改变爆破抵抗线与民房的相对位置,选用合理的微差间隔时间及临近最终边坡时采用预裂爆破技术,保证了民房安全和露天矿扩帮剥离,取得了显著的经济效益和社会效益。
Through site blasting tests and monitoring of blasting vibration effect, using the blasting designs of explosive space charging in the hole and millisecond delay detonation both in the hole and among the holes,changing the relative position between the minimum burden and nearby living buildings,and ado pting the reasonable space time of millisecond delay and splitting blasting method near the final slope,the safety of nearby living buildings and stripping excavation of openpit mine have been ensured.By using this blasting technology,the remarkable economic benefits and social effects have been obtained.
