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 2):
The method according to  claim 1 , wherein the step of calculating diffracted wave travel times for each piece of the single-shot data from a seismic wave shot point position of the each piece of the single-shot data through any imaging point position in an underground imaging space to a seismic wave geophone point position of the each piece of the single-shot data according to geophone spatial positions and the seismic wave migration velocity file corresponding to the each piece of the single-shot data comprises:\n calculating travel times t S  from a seismic wave shot point position of each piece of the single-shot data to individual imaging point positions in an underground imaging space, according to geophone spatial positions and the seismic wave migration velocity file corresponding to the each piece of the single-shot data; calculating travel times t R  from the individual imaging point positions in the underground imaging space to a seismic wave geophone point position of each piece of the single-shot data, according to the geophone spatial positions and the seismic wave migration velocity file corresponding to the each piece of the single-shot data, wherein the travel time t R  and the travel time t S  of each piece of the single-shot data at one imaging point correspond to each other; and adding each of the travel times t S  and the travel time t R  corresponding to the travel time t S  for each piece of the single-shot data, to obtain a plurality of diffracted wave travel times corresponding to the each piece of the single-shot data.
