Study on the coal erosion regularity using seismic liyhology information

In this paper,the coal erosion model is designed and simulated numerically.The coal erosion regularity is studied on synthetic data.Multiple seismic lithology information is obtained by use of seismic attribute technique,spectrum decomposition technique,seismic faces analysis and seismic inversion technique.The coal erosion regularity is comprehensively analyzed and studied by seismic lithology information with drilling and mining geology data.Comparison with conversion interpretation method,the multiple seismic lithology interpretation method can accurately locate the coal erosion range.
