中文摘要：

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。

英文摘要：

In blasting vibration monitoring at Nanshan thirty - fifth step of Dexing copper mine in Jiangxi,the data recorded by three vibration measuring devices with the same parameter is greatly different with each other. This paper briefly analysis the propagation law and stress loss of stress wave when it goes from one medium to another medium. It was concluded that the water on blasting step can reduces the vibration velocity of blasting earthquake wave and the extent of vibration velocity dropping is associated with wave resistance of two different medium, the weakening effect of water on vertical vibration velocity is great, but is not obvious on horizontal vibration velocity.
