Abstract
In order to obtain the dynamic response law of pillars in underground goafs under the action of seismic wave, the acceleration response and dynamic displacement response law of pillars were studied by using the MIDAS-GTS/NX finite element simulation software based on a mine. Results are shown as follows: (1) the response of the top acceleration and displacement of the pillar and roof of goaf is larger than that of the bottom. (2) The cross-sectional area of pillars has a significant effect on the dynamic response of pillars in underground goafs. The stability of pillars with large cross-sectional area is generally better. (3) The position of pillars has a significant effect on the dynamic response of pillars. The dynamic response of pillars in the center of goaf is the strongest. However, the dynamic response of pillars in the edge of goaf is smallest. (4) The laws of acceleration and displacement response of pillars in goafs under horizontal seismic wave are revealed, which provides reference for mining design and earthquake damage prevention.
