Comprehensive geophysical detection of some 4 rock-dumping place was carried out with shallow seismic method and high density resistivity method.The data obtained by shallow seismic reflection and high-density resistivity method was analyzed and studied,including the comparison of the data obtained by different detecting methods,the comparison of the data obtained by same detecting methods but from different detecting devices and the comparison of the data obtained from same detecting places but in different time.Combining geological data,geophysical abnormities were distinguished,and cranny,weak face and slipping face in the rock-dumping places were defined.It provides a scientific foundation for the forecasting and alarm of geologic hazard in mine.
