In order to avoid the useless tunneling and the low mining rate, the mine seismograph measurement new technology is applied to measure the coal seam washout zone with long distance and high resolution. Based on the analyzing geophysics characteristic of the coal seam washout zone, this paper investigates the characteristics of time-distance curve of the measurement technology, and studies the application example of detecting the development and boundary scope of the old river-seam coal seam washout zone long-distance ahead of tunnel. The result shows that the measurement of the development and the boundary scope of the coal seam washout zone by using the mine multi-wave seismograph meet the practical requirement with small error and being consistent with the actual conditions during the process of mining.
