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 5):
The method according to  claim 4 , wherein the step of extracting amplitude sampling points satisfying a preset condition from each of the amplitude sampling point sequences according to the Mahalanobis distances of all the amplitude sampling points ranked in the preset order in the corresponding amplitude sampling point sequence comprises:\n calculating, as for any one of the amplitude sampling point sequences, the number of the sample points to be removed from the amplitude sampling point sequence, according to the Mahalanobis distance of each of the amplitude sampling points ranked in the preset order in the amplitude sampling point sequence and a preset Mahalanobis distance threshold of a reflected wave amplitude sampling point; performing sampling point removing processing on the amplitude sampling points ranked in the preset order in the amplitude sampling sequence, according to the preset Mahalanobis distance threshold and the number of the sample points to be removed, to obtain remaining amplitude sampling points in the amplitude sampling point sequence; and extracting the remaining amplitude sampling points as amplitude sampling points satisfying a preset condition in the amplitude sampling point sequence.
