摘要 液化氧气致裂岩体是当今发展的一种新兴爆破技术。采用现场试验的方法,对爆破振动测试数据以及致裂爆破效果进行对比分析,研究此技术在露天矿山应用的实际效果。结果表明:液氧致裂爆破技术在实施过程中无任何有害气体产生,对周边永久边帮振动破坏小。爆破后无明显飞石产生,最大限度地减少了对周边的硬性破坏。该技术适用于对爆破扰动控制要求高的特殊环境下的爆破,具有推广意义。 Liquefied oxygen cracking rock mass is a new blasting technology developed today.The field test method is used to compare and analyze the blasting vibration test data and the cracking blasting ef⁃fect,and the actual effect of this technology in open-pit mines is studied.The results show that there is no harmful gas generated during the implementation of liquid oxygen blasting technology,and the vibration damage to the surrounding permanent side is small.There is no obvious flying rock in the liquid oxygen blast⁃ing,which minimizes the hard damage to the surrounding.This technology is suitable for blasting in special environment with high requirements for blasting disturbance control,and has popularization significance.
