| Περίληψη: | Underground mine surveys present unique challenges, including the logistics of deploying an energy source, placing geophones in solid rock, managing reverberation from the adit, and ensuring safety. We present the results of seismic surveying at the historic Deer Trail Mine in south-central Utah (USA). The mine is located along the eastern side of the Tushar Range. The surveys utilised a narrow, mostly horizontal adit, 120–510 m below the ground surface. The country rock consists of highly fractured and mineralised Permian to Pennsylvanian quartzites, shales, and limestones. A short test of a 96-channel common midpoint (CMP) P-wave profile was conducted using an accelerated weight-dropper source. We supplemented the P-wave survey with tests of surface-wave dispersion and horizontal-vertical spectral ratio modelling for shallow S-wave structure. These tests confirmed the capability to map shallow, small-scale structure. A conventional CMP 264-channel survey with an explosive source covered 1728 m. A static recording array was used for both surveys with 4.5-Hz vertical geophones. The conventional CMP profile imaged horizontal and dipping reflectors down to about 2000 m, interpreted as lithologic variations in the bedrock. Our study demonstrates the potential for high-resolution seismic exploration in an unconventional and challenging setting to guide the exploitation of deeply buried mineral resources.
