Abstract:
A coal collapse column identification method and related apparatus that includes acquiring seismic shot gather data in a target region and a seismic wave migration velocity file; calculating a diffraction wave travel time of each piece of single-shot data at different imaging points according to the data; performing Mahalanobis distance calculation processing on each single-shot data and the diffraction wave travel time thereof to acquire a diffraction wave amplitude value sample point of each piece of single-shot data; imaging respectively on a diffraction wave of each piece of single-shot data; and superposing imaging processing results of all the single-shot data corresponding to the seismic shot gather data to obtain a diffraction wave imaging result of the seismic shot gather data so as to facilitate coal collapse column identification according to the diffraction wave imaging result. A diffraction wave corresponding to seismic shot gather data is extracted through a Mahalanobis distance.

Claim (Index 6):
The method according to  claim 5 , wherein the step of imaging respectively the diffracted wave amplitude sampling points of each piece of the single-shot data to obtain a diffracted wave imaging result of the each piece of the single-shot data comprises:\n adding the amplitude value sampling points satisfying the preset condition that are extracted from each of the amplitude sampling point sequences, to obtain a diffracted wave imaging result corresponding to the each of the amplitude sampling point sequences; and superposing the diffracted wave imaging results of all the amplitude sampling point sequences corresponding to the single-shot data, to obtain a diffracted wave imaging result corresponding to the single-shot data.
