| 摘 要： | 应用萨道夫斯基经验公式，研究2007年12月20日宁夏大峰矿特大爆破S波最大振幅的衰减特性，结果表明。银川盆地衰减比周边地区严重，大体可以看出银川盆地的东部边界和南部边界。在爆破点东73km和南122～151km．该结果和地质上给出的银川盆地的边界基本吻合。

| Abstract: | Study on attenuation characteristic of S waves maximum amplitude in the very large blasting in Dafeng mine, Ningxia on 20 December, 2007 with the Sadaovsk Formula. The result shows that： attenuation is more intensive in Yinchuan basin than other adjacent regions. The east and south boundary of Yinchuan basin can be found at east 73 km and south 122 to 151 km from the blast. This result is almost the same as the boundary given in geology. |
