Abstract: At present,developing as a mining geological surveying technique with stronger practicality,the in-seam seismic technique has been applied successfully.However,this technique has a definite suitable range,and is not applicable to all coal seams in all regions.Based on a lot of in-seam surveying data,the physical properties of coal seams and their surrounding rocks and the geometric shapes of coal seam occurrence are analyzed.The adaptability and classification of in-seam wave surveying in our country are concluded.
