摘要
The paper presents the results of initial stress measurements at the Udachny mine located below the open pit. Measurements were carried out by methods of slot unloading according to the method of the Institute of Mining Engineering, Ural Branch of RAS and circular electrical probing. To clarify the degree of influence of the open pit on the measured stresses and the actual rock pressure hypothesis, finite-element modeling of the stress-strain state of the sub-pit rocks under different hypotheses of rock pressure was carried out. The gravitational character of stress distribution in the host rocks (dolomites, limestones) and gravitational-tectonic - in an ore body (kimberlites) is established.
