| Abstract: | At the beginning of the analysis we indicate the geological and geophysical property of the mined -out areas. Based on the physical property in mined - out areas, the paper formulated the feasibility of detection mined - out areas by seismic reflected wave method and worked out the mathematical model of partial mined - out areas according to principle of ray tracking and wave equation ; It analyzed the typical features of response in mined - out areas with different parameters by the means of simulating from the point of view of kinematics and dynamics; and the data of the mined - out areas is studied. In the end, it generalizes the reflection features and identifications of mined - out areas in seismic data linking up with practical facts. |
