Mine working face inter-lane seismic wave CT detection method

The invention discloses a mine working face inter-lane seismic wave CT detection method which is a highly precise detection method for a geologic anomalous body in the mine working face, namely, seismic wave CT detection which is similar to medical CT and relates to a practical technique by taking the coal mine coal face as a research object and utilizing an upper lane and a lower lane for CT detection. An observation system relates to the relative relationship between a trigger point and a receiving point in space, and generally, the trigger point (adopting mining explosive as a seismic focus) is arranged at one lane, and the receiving point is arranged at another lane, and the observation mode of 'one-trigger, multi-receiving, and one-explosion, one-release' is adopted. After a coordinate system is established, the coordinate parameters of each point of the observation system are determined, and inversion calculation is conducted by utilizing an inter-lane seismic wave CT tomography technique, thus obtaining seismic velocity equal CT inversion slice in the working face so as to accurately and effectively judge the geological structure and the anomalous body trace in the working face. The method has better pertinence to the geological structure and the interpretation of anomaly thereof, and can provide reliable technical parameters for safe production in mines. The method broadens the application scope of the seismic wave CT detection technique and improves the accuracy for geologic anomalous body detection in the mine working face.
