Abstract
A system for seismic tomographic measurements is presented, and both hardware and software are described. The system is intended to operate in the distance range 100-1000 m. An explosive source is used to generate signals which are picked up by receivers at the surface and in boreholes. Tomographic results from two field experiments are presented. The first experiment concerns mapping of an ore body in a mine, whereas the second concerns rock quality determination.
