The paper presents the use of selected non-destructive testing methods for the purpose of specifying information on weathering and cracking of surface layers of granite rock massif in the medieval Jeroným Mine (the Czech Republic). Two non-destructive methods have been tested, namely the measurement of ultrasonic pulse velocity and the measurement of Schmidt hammer rebound value. Field measurements were performed in two selected galleries, which were mined out by hand tools during the oldest period of mining activities in this locality, and later they were extended by blasting operations. Measurements in these galleries have enabled to analyse rock massif cracking and weathering depending on used mining method.
