Modeling of technical solutions to strengthen workings for LLC "Institute Gipronickel"

Description of the problem

  • 1
    Making design decisions based on irrelevant data on the properties of rocks and massifs leads to a decrease in economic efficiency and safety of production.
  • 2
    The need to model the possibility of strengthening the destroyed rock mass.
  • 3
    The need to take into account the experimentally established connections between the degree of reinforcement, the modulus of deformation and the velocity of propagation of transverse waves.

What was done

Based on modeling in CAE Fidesys, it was found that the main measure to increase the stability of the workings in conditions of increased horizontal stresses is to strengthen the rock mass by tightening the support.
