Introduction. Mineral deposits opencast and underground mining is accompanied by excavation and conveyance of enormous rock masses. As a result, geological medium natural stress state is disturbed. Its balance restoration is accompanied by dynamic events of various forms and intensity, often catastrophic. That is why the problem of deposits safe exploitation is relevant in scientific and practical terms. At the territory of the Ural region there are several regions where the level of technogenic load is estimated to be potentially dangerous. One such region is Solikamsk-Berezniki region; the largest in the world, the Upper Kama (Verkhnekamskoe) potassium salt deposit (VKMKS) has been mined there since 1932, along with hydrocarbon, underground waters, and other mineral deposits. There is also a large reservoir there. Geological medium within the deposit is in the state of unstable balance. Catastrophic dynamic events of 1995, 1999, and 2006 give evidences of this.
Research aim is to generalize the experience of studying dynamic events at VKMKS and substantiate the criteria of their forecasting.
Research methodology. Generalization and analysis of the results of geological and geophysical survey made at VKMKS.
Research results. Structural-tectonic models of the Upper Kama deposit and its separate parts have been built, within the limits of which hazardous dynamic events took place.
Conclusions. Features characterizing deposit sites within which dynamic events took place have been formulated. These features can be considered as criteria for potential dynamic events forecast.

Key words: Upper Kama (Verkhnekamskoe) potassium salt deposit; dynamic events; forecasting; criteria; geological and geophysical data.
