CMICT码头高边坡开挖的预裂爆破技术

Pre-splitting Blasting in the High Rock Slope Excavation for CMICT Dock

介绍了微差预裂爆破和微差密孔预裂爆破在CM ICT码头高边坡开挖工程中的应用。结果表明,采用微差预裂爆破和微差密孔预裂爆破可以显著降低预裂爆破的振动强度,从而扩大了预裂爆破的使用范围,降低了爆破成本。

The application of MS-delay pre-splitting blasting and MS-delay close-drilling pre-splitting blasting in the high rock slope excavation for CMICT dock was introduced. The results show that the MS-delay pre-splitting blasting and MS-delay close-drilling pre-splitting blasting can notably reduce the vibration intensity induced from pre-splitting blasting, expand the scope of pre-splitting blasting; therefore reduce the blasting costs.
