基于小波理论的井下深孔爆破振动信号辨识与能量衰减规律分析
|
摘要
在爆破漏斗试验的基础上,制定了某矿山的深孔爆破方案,在现场进行了深孔爆破试验并实施了振动监测。采用小波分析方法对深孔爆破振动信号频带能量分布进行了分析,发现Ⅳ号测点的频带能量分布与其它4个测点明显不同,从而判定Ⅳ号测点数据失真。利用剩下的4个测点的数据,编制程序计算得到各测点X、Y和Z三向的能量和总能量,回归得到总能量的衰减公式。研究结果表明:在距爆点0～75 m范围内,爆破振动能量随距离增大而迅速降低;在距爆点75～250 m,爆破振动能量维持在一个较低水平且衰减速度非常缓慢;超过250 m以后,爆破振动能量几乎为零。
Based on blasting crater tests,a mine's deep-hole blasting scheme design was set up,the on-the-spot deep-hole blasting test and the vibration monitoring was done.The deep-hole blasting frequency band energy distribution was analyzed in wavelet analysis method.The results show that the energy distributions of the No.4 measuring point are different with the other four,which show that the data of No.4 point are distortion.Adopting the data from other 4 measuring points,the energy of X,Y,Z three directions and the total energy was made by programming program,and the total energy attenuation formulas was made by regression analysis.The study show that when the blasting point is within 0~75 m,the energy of blasting vibration decreases rapidly with the distance increases,within 75~250 m,the energy maintains at a lower level and the attenuation is very slow,when the distance exceeds 250 m,the energy is almost to zero.
