厂坝铅锌矿是重点开发矿区,其山体陡峭,工业爆破时容易造成山体滑坡。为研究边坡稳定性,我们使用人工地震方法,在厂坝铅锌矿区500米范围内,布设了两条交汇测线系统,反演和正演了该工作区域的浅部地壳速度剖面,得出地表直达纵波的平均速度为1.74公里/秒;对1号、2号公路地区和1至3号平台斜坡地区进行了速度分层,确定从地表向下540米深可大致分为五个速度层,速度从1.74公里/秒到2.99公里/秒。本文结果表明,CBY—2爆破地震仪可用于浅层地震勘探。我们所用的数学处理方法亦可在其它浅部地震勘探中使用。
Changba lead-zinc mine is the focus of the development of mining, the steep mountain, industrial blasting is likely to cause landslides. In order to study the stability of slope, we use artificial seismic method to lay down two intersecting survey lines in the area of 500 meters in Changba Lead-Zinc Mining Area, and invert and forward the shallow crustal velocity profile in the working area. The average velocity of the direct wave on the ground surface is 1.74 km / s. Velocity stratification is carried out on the road slopes of No. 1 and No. 2 and No. 1 and No. 3 platforms. It can be divided into five velocity layers , From 1.74 km / s to 2.99 km / s. The results show that the CBY-2 blasting seismometer can be used for shallow seismic exploration. The mathematical treatment we use can also be used in other shallow seismic surveys.
