ABSTRACT
The author presents the results of underground gravity survey carried out in three galleries of object "Osówka", which is part of the post-war complex "Rise" in the Owl Mountains in Poland. The structure was drilled in the gneiss. The aim of this survey was detection of the hypothetical galleries lying below the elevation level of survey. Results have shown the possibility of using the gravimetric method to explore galleries located under the measurement profile. Carrying out the correct interpretation is possible on condition the precise spatial projection of existing galleries. This projection allows for correct calculation of the gravitational effect of the excavation and remove it from measured values of gravity. Unfortunately, this survey has not confirmed the existence of an unknown gallery.
