A device using measurement of local deformations on conical ended borehole bottom was used for long term monitoring of stress changes induced by underground mining activity. The problems of rock stress and its measurement have been investigated in the Institute of Geonics for a long time. At present, we need a method for determination of stress and its changes as reaction to the impact of the underground human activity. The paper deals with principles and used metod of strass measurement, basic description of the equipment and experiment in situ. A new device for determination of stress change tensor was developed on the basis of strain measurement applied to a conical shaped borehole bottom. Within the frame of this development a special probe interlocked to data logger was realized. This type of device was used for the long-term monitoring of the stress – strain changes.
