Underground mining tunnels constitute a very particular environment for radio wave propagation - with characteristics of both indoor and outdoor "Regular" environments. This paper shows how a general-purpose Wi-Fi-based indoor positioning system, OwlPS (Owl Positioning System) was adapted to work in that particular environment. A series of experiments, conducted in a formerly exploited gold mine at 70 meters below the surface, across about 400 meters of drifts, is then introduced; it primarily aims at determining the positioning accuracy that can be reached in such a context with a Wi-Fi-based positioning system using the signal strength at 2.4 GHz.
