SUMMARY Coda waves are highly sensitive to changes in the subsurface; we use this sensitivity to monitor small stress changes in an underground mine. We apply coda wave interferometry to seismic data excited by a hammer source, collected at an experimental hard rock mine in Idaho Springs, CO. We carried out a controlled stress‐change experiment in a mine pillar and we show how coda wave interferometry can be used to monitor the in situ stress change with modest hardware requirements.
