Abstract: The quality of seismic imaging is great affected by the complex lithology and salient relief surface of the mountainous area.This paper takes the Peigou coal mine 31 mining area as a study example.Firstly, different equipment for boring hole in the data acquisition stage under different surface conditions is adopted to ensure the quality of the original data.Secondly,a "two step" static correction method is used to solve the imaging problem in the stage of processing data that causing by the change of altitude and lithology. Through the above measures,high quality results are obtained.Preliminary validation of the mine production shows that the method is correct,and its accuracy is good.
