Abstract
For the activation of seismic waves in weak e-lastic medium (medium with poor elasticity), how to make better use of its elastic properties is the key to improving shooting effects. According to the shooting characteristics of borehole dynamite source, shooting with large areal array increases the acting surface for the weak elastic medium, which means the elastic features of weak elastic medium can be better revealed and better elastic waves can be excited. Areal array shooting experiments with different group lengths are carried out in loess tableland and limestone regions, respectively. Analysis of the experimental data shows that besides the improvement of signal-to-noise ratio of seismic waves, the energy of seismic waves enhances with the increase of group length. The results show that increasing the acting surface can effectively improve the shooting effects in weak e-lastic medium.关键词
