The article analyzes the results of studying the physical-mechanical properties of the rocks of the Charmitan gold deposit (Uzbekistan) and estimates the liability of the deposit to rock bursts. It is shown that there are rocks and ores at the deposit with high strength properties that are capable to accumulate significant potential energy and undergo brittle failure. It is concluded that the Charmitan field, by the physical-mechanical parameters of host rocks, belongs to the category characterized by the manifestation of rock pressure in a dynamic form.
