| 摘 要： | 透射地震CT技术应用于矿井工作面中小断层和陷落柱的探测在理论上是可行的.通过3个室内物理模型的模拟,证明透射地震CT技术能够对介质差异明显的界面反应清晰,即对模拟的煤层中小型断裂构造和高速异常体反应灵敏.因而该技术可有效地应用于矿井工作面中小断层和高速陷落柱的探测,为其在井下的实际应用提供了充分的证据.

| Abstract: | It is theoretically feasible that transmission seismic layer computer tomography technique can be used to detect the small faults and collapse columns in the mining working face. Three indoor physical simulations verify that the transmission seismic layer computer tomography technique has a strong response to the interface where media has apparent difference (responding sensitively to the small faults and the high-speed anomalous bodies in the simulated coal seam). Therefore, this technology can be effectively used in the detection of small faults and high-speed karsts collapse columns in the mining working face. The present work provides support for its practical application in the mine. |
