Abstract

Refraction and tomography surveys were used with good results for rock mass damage classification in pillars in the El Teniente underground mine. The panel caving system is used and the damage is caused by the advancing caving front in hard primary ore prone to rock bursts. Seismic refraction was an efficient method for sampling large distances of tunnel in a short period of time and did not suffer from mine development noise. Tomography was an effective diagnostic tool for showing the differences in rock quality in individual pillars. Zones of low velocity indicate damage, while high velocities indicate good rock quality and applied stress.<br />Refraction and tomography surveys were used with good results for rock mass damage classification in pillars in the El Teniente underground mine.
