摘要

为研究干冰粉气动破岩的冲击振动危害效应，试验测试了干冰管内气体压力变化和地表的振动速度，用希尔伯特-黄变换方法研究了干冰粉气动破岩振动衰减规律。研究结果表明：1、干冰粉气动破岩最大振动速度在11m时下降至2.5cm/s以下，是一种振动很小的新型破岩方式；2、经测量致裂管内压力峰值达到50.85MPa，计算能量的TNT当量符合萨道夫斯基公式；3、使用HHT对干冰粉气动破岩振动信号进行时频分析，能量在频域上主要分布于0-100Hz，振动持续时间0.3s。

Abstract

In order to study the impact and vibration hazard effects of dry ice powder pneumatic rock breaking, the experiment tested the gas pressure change in the dry ice tube and the vibration speed of the ground surface, and the attenuation law of dry ice powder pneumatic rock breaking vibration was studied by the Hilbert-Huang transformation method. The research results show that: 1. The maximum vibration velocity of dry ice powder pneumatic rock breaking drops below 2.5cm/s at 11m, which is a new rock breaking method with little vibration;2. The peak pressure in the fracturing tube is measured to reach 50.85MPa, and the TNT equivalent of the calculated energy conforms to the Sadowski formula; 3. The time-frequency analysis of the dry ice powder pneumatic rock breaking vibration signal is carried out by using HHT, and the energy is mainly distributed in the frequency domain. 0-100Hz, vibration duration 0.3s.
