摘要/Abstract

摘要：

为减少传统爆破易产生强振等次生灾害问题,研发破岩气体发生器;通过评估破岩气体发生器的燃烧安全性,开展现场破岩试验并监测其振动,采用品质可调小波变换(TQWT)和希尔伯特-黄变换(HHT)分析方法,提取得到气体爆破信号的主分量,并分析信号不同分量时频特征。研究结果表明:新型破岩气体发生器运输安全性高、燃烧稳定性好,振动强度低,在土石方爆破方面具有显著优势。破岩气体爆破信号各分量幅值、能量占比和相关性系数满足非线性正相关关系。优势分量瞬时能量峰值数量与炮孔分段装药段数密切相关,破岩气体爆破时应采用差异化装填方式,炮孔分段装药应适当增加孔口和孔底部药量,以达到最优化的爆破效果。新型破岩气体发生器爆破技术具有显著减振降损作用,适合在土石方爆破工程中推广应用。

Abstract:

In order to reduce the problem that traditional blasting was prone to produce secondary disasters such as strong vibration, a new rock breaking gas generator was developed. The combustion safety was evaluated, the field test was carried out and the blasting vibration was monitored. The principal components of the gas blasting signal were extracted using the TQWT and Hilbert Huang transform analysis methods, and the time-frequency characteristics of different components of the signal were analyzed. The results show that the new rock breaking gas generator has high transportation safety, good combustion stability and low vibration intensity, and it has significant advantages in soil and rock blasting. The amplitude, energy ratio and correlation coefficient of each component of rock breaking gas blasting signal meet the nonlinear positive correlation. The quantity of the instantaneous energy peak of the dominant component is closely related to the number of blasting sections of the blast hole. The differential charging method should be adopted in rock breaking gas blasting, and the charge quantity at the orifice and the bottom of the blast hole should be appropriately increased in order to achieve the optimal blasting effect. The new rock breaking gas generator blasting technology has significant vibration and damage reduction effects, and is suitable for popularization and application in soil and rock blasting engineering.

Key words: rock breaking gas generator, safety, energy distribution, instantaneous energy, tunable Q-factor wavelet transform(TQWT)
