深孔松动爆破技术在特高陡边坡危岩体清除中的应用

高陡边坡危岩体的处理由于边坡地形复杂、高差大、机械设备利用率低,采用膨胀水泥静态爆破技术的成本高、效率低、劳动强度大且危险系数极大。利用三脚支架潜孔钻机,采用深孔松动爆破配合爆破振动监测手段处理高陡边坡危岩体效率高,成本、劳动强度及危险系数都大大降低,爆破对岩体影响小,有利于高陡边坡的稳定。本工程对高陡边坡地质灾害的治理具有很好的借鉴意义。

APPLICATION OF DEEP-HOLE LOOSENING BLASTING TECHNOLOGY IN THE CLEARANCE OF DANGEROUS ROCK OF THE ULTRA-HIGH AND STEEP SLOPE

Using static blasting technology of the expansive cement to remove dangerous rock body of the ultra-high and steep slope will lead to high cost,low efficiency,great labor intensity and high risk because of the complexity slope terrain,large height difference and low utilization rate of machinery.Deephole loosening controlled blasting technique combined with blasting vibration monitoring had higher efficiency and lower cost,and labor intensity and risk made little influence on the rock,which were benefit for the stability of the ultra-high and steep slope.The results could provide certain reference for geological hazard control of the ultra-high and steep slope.
