在江西德兴铜矿爆破震动的监测过程中,南山35水平台阶三台参数设置相同测震仪所获数据相差较大,结合实例浅述了应力波在两种不同介质间的传播规律,尝试性地解释了应力波介质面上的应力损失。并得出结论:爆破台阶表层有部分积水的区域可对爆破振动速度有削弱作用,削弱程度与两种介质的波阻抗有关;积水区域对垂直向的振速削弱作用较大,水平方向作用不明显。
In the process of monitoring the blasting vibration of Dexing copper mine in Jiangxi Province, the data of the same seismometer set by the three parameters of 35 horizontal steps in Nanshan differs greatly. The propagation law of stress wave in two different media is described with examples Sexually explains the stress loss on the stress wave surface. And it is concluded that the region with some water on the surface of the blasting stage can weaken the blasting vibration velocity, and the degree of weakening is related to the wave impedance of the two media. The water-seeking region has a great effect on the vertical vibration velocity weakening and the horizontal direction The role is not obvious.
