摘要
兰尖铁矿为保护平硐溜井和边坡,工程技术人员进行了孔内孔间微差爆破技术的探索。确定合理的微差间隔时间,既是保证爆破质量的需要,又是达到爆破降震的关键。叙述了孔内微差爆破时间间隔的确定、起爆方式、网络连接及其应用效果。
To protect the adit pass and slope, the mass of engineering and technical personnel in Lanjian Iron Mine have explored the in-hole and between-holes microsecond blasting technology. To determine rational microsecond delay time is both the requirement of ensuring blasting quality and the key to achieve blasting vibration reduction. The paper describes the determination of in-hole and between-holes microsecond delay time, the detonation mode and the network connection and their application effect.
