Abstract: The in-seam seismic exploration is usually carried out in one or several roadways.In this paper,the method,the applied apparatus and the data analysis and interpretation of in-seam seismic exploration performed in borehole are discussed.It is believed that this method is a feasible one,expanding the application scope of in-seam seismic exploration,and having an important practical value for the detection of small-scale structures by use of in-seam seismic exploration.
