Abstract
We report testing results for a 50 m laser strainmeter installed 300 m under the ground in a mine of PJSC Priargunsky Industrial Mining and Chemical Union (Krasnokamensk) and demonstrate its ability to record microseisms and waves of infrasonic-sonic bandwidths. Processing and interpretation of the collected data provides information about microseismic to tidal strain changes in the Transbaikalian region.
