In this article, the authors present the outcomes of their studies on the dynamic characteristics of ground and amplification of ground motions above abandoned mines and discuss their implications. In addition to the effects of some parameters associated with extraction, some topographic effects on ground motions in areas with abandoned mines are also investigated and results are presented. It will be clearly shown that ground amplifications may be quite large on the abandoned mines where extraction is carried out by room and pillar technique or open-pit mines. The ground amplifications may be 3-5 times that at the base. Particularly these amplifications may be quite large particularly near steep cliffs.
