摘　　要：1 032平盘开拓工程与56泵站的最小距离仅75 m。为了确保泵站安全,在爆破中采用了OR ICA导爆管逐孔起爆技术和积极的防护措施。结果表明,爆破质点振动速度和爆破飞石都满足了工程要求,达到了预期的效果。The shortest distance between the I 032 berm development operation and the 56 pump station is only 75 meters. In order to ensure the safety of the pump station, the ignition in borehole sequence with ORICA non - electric detonator and pro - active protection diction is applied. The result shows that the blasting particle vibration velccity and flyrock have met the requirement of engineering. The expected result of blast is achieved.
