Surface collapse over abandoned sub- surface coal mines continues to be a problem in many parts of the world. High-resolution P-wave reflection seismology was successfully used to locate water-filled cavities in a 1-m (3-ft) thick coal seam at depths of 9 m (29 ft) in southeastern Kansas. A dominant frequency of 275 Hz was attained enabling us to delineate the top of the coal seam. To our knowledge, this study is one of the first to locate water-filled coal mine cavities at depths of less than 30 m (100 ft) wing high-resolution P-wave seismic reflection techniques.
