Inter alia, CAE Fidesys applies the strength geomechanical analysis for scientific support of ore mining technical solutions at the mines of the Polar Division of MMC Norilsk Nickel PJSC.

Problem description

Adopting design solutions based on irrelevant data on the properties of rocks and massifs leads to a decrease in economic efficiency and safety of production.
The need to model the possibility of strengthening the destroyed rock mass.
The need to take into account the relationships found in tests between the degree of strengthening, the elastic modulus and the propagation velocity of transverse waves.

Achievement

Modeling based on CAE Fidesys revealed that rock mass strengthening behind the support tie is the main measure for better mine structure stability in case of increased horizontal stresses.
