摘　　要：通过计算机仿真图形计算，对不同激发频率、不同采空区埋深、不同采空区尺寸和不同激发源部位进行了地震波正演模拟，展示了空洞对地震波场影响的Ｓｎａｐｓｈｏｔｓ动态波场图像，揭示了不同地震方法与采空区条件的相关规律，论证了浅层地震采空探测属点源振动与固体散射或绕射的探测机理。Seismic forward simulation was made at different vibration frequencies, different depths of the mine-out area, different sizes of the mine-out area, and at different positions of semission sources by computer emulation graphic calculation. The Snapshot images of dynamic seismic field reveal the correlation between the seismic methods and conditions of mine-out area. And it is proved that the mechanism of detection is point source vibration and solid scattering or diffraction.
