The article is devoted to the investigation of brittle fracture formation in underground mines of Kirovsk branch of JSC “Apatit” by applying numerical simulation and subsequent comparison with the results of field data. It includes the results of studies of rock failure forms with different directions, values and stress ratio, as well as the measures to reduce stress by drilling relief holes. Brittle fracturing and dependencies of its formation based on many factors, including mining, geological and geomechanical factors were researched. The results serve as the basis for the next research aimed at searching and grounding the effective ways to stabilize mine tunnels in case of brittle fracturing.
