Application of collapse column identification technology based on spectral decomposition

In order to solve the identification problem of coal field collapse columns, the collapse column X7 exposed in exploration area 1200 of Xingdong Mine was taken as research object, the basic information from seismic exploration, logging, site disclosure and comprehensive geological research results were integrally used. Based on advanced spectral decomposition technology, the spatial distribution of the collapse column X7 was estimated on seismic attribute profiles. Application study in Xingdong area showed that spectral decomposition technology is superior to the conventional seismic attribute analysis method for collapse recognition. Spectral decomposition is reliable and effective, and provides a basic tool for prediction of complex geological body in other areas.
