| Abstract: | Aiming at the problem of forecasting coal and gas outburst and water eruption caused by karst collapse column in deep coal mining in east China,the principle and method of minimum travel-time of seismic tomography were discussed. And the model of ground stress anomaly and karst collapse columns was inversely deduced for tomography. The result shows that this method can effectively forecast the ground stress anomaly. So it is significant both theoretically and practically. |
