摘要：随着破岩技术的更新发展,传统炸药破岩方法的弊端日益凸显。液氧储能破岩方法作为新型的非炸药破岩方法,其爆破反应机理不明确,相关科学问题有待研究。为进一步确定液氧储能破岩爆破特点,解决工程现场经验法应用难题,开展了液氧储能爆破现场振动测试,分析质点峰值振动速度变化规律及衰减特点;进行室内小尺寸药包爆破试验,明确小尺寸液氧药包爆破关键因素。相关试验结果表明:液氧储能破岩方法能有效破碎岩石,整个爆破过程中扬尘和噪音都控制在较低水平,单炮条件下3 m、6 m和10 m处测点的质点峰值振动速度分别为3.04 cm/s、1.24 cm/s和0.62 cm/s。而小尺寸药包试验则表明要想液氧药包能成功起爆,取得良好破碎效果,则必须作用以合适的充气时间、压力,避免出现爆燃等现象。充气时间和充气压力越大,药包内部吸收剂吸附液氧越多,液氧含量更容易达到饱和,药包更容易成功起爆。总的来说:液氧储能破岩方法与传统炸药方法相比具有振动小、绿色环保无污染等特点,具备在工程爆破领域进一步推广使用的明显优势。
As rock-breaking technology advances,the limitations of traditional explosive methods are increasingly evident.The liquid oxygen energy storage method,a new non-explosive technique,presents an uncertain blasting mechanism and scientific challenges that must be addressed.Field vibration tests were conducted to analyze the variation trends and the decay characteristics of peak vibration velocities in particles to further characterize the liquid oxygen energy storage rock-breaking blasts and address the challenges of applying empirical methods on-site.Additionally,indoor small-scale blasting experiments were performed to identify key parameters for small liquid oxygen charges.The experimental results reveal that the liquid oxygen energy storage effectively fractures rocks while maintaining low dust and noise levels.Peak particle vibration velocities at 3 m,6 m,and 10 m under single blast conditions were 3.04,1.24,and 0.62 cm/s,respectively.The small-scale charge tests reveal that for the liquid oxygen charge to detonate successfully and effectively fracture the rock,appropriate inflation time and pressure are required to prevent detonation and other issues.Increased inflation time and pressure lead to more significant adsorption of liquid oxygen by the charge′s absorbent,facilitating saturation and enhancing detonation probability.Overall,the liquid oxygen energy storage method stands out due to its low vibration,environmental friendliness,and non-polluting nature,marking a significant potential advancement in engineering blasting.
