在建立典型煤田陷落柱地震地质模型及最大炮检距不同的观测系统的基础上,通过理论分析和地震照明度分析对比了炮检距对地震成像的影响。然后采用射线追踪算法进行正演模拟,分析不同最大炮检距条件下的观测系统对陷落柱探测精度的影响。得到最大炮检距越小对陷落柱的解释精度越高的结论。
Based on the establishment of the seismic geological model and the observation system with the largest offset of the typical collapse column in the coalfield, the influence of offset on seismic imaging was analyzed by theoretical analysis and seismic illumination analysis. Then the ray tracing algorithm is used to simulate the forward modeling, and the influence of the observation system under different maximal offset conditions on the detection accuracy of the collapse column is analyzed. The conclusion that the lower the maximum offset is, the higher the interpretation accuracy of the collapse column is.
