RocTunnel3 Across Applications

  • Underground Mining
  • Tunnels
  • Underground Facilities

Underground Mining

Locate and assess block failures at multiple scales after blasting. You can characterize block failures from natural and excavation-induced joint sets, analyze required support capacities, and design your reinforcements.

Underground Mining

Tunnels

Assess and locate block failures in staged construction, design liners, and reinforcements for safe operations.

Tunnels

Underground Facilities

Assess the geologic hazards of underground energy and storage facilities, including seismic loading in complex geological domains.

Easily update your model with new survey data and perform probabilistic block stability analyses for safe long-term operations.

Underground Facilities

RocTunnel3 Seamlessly Integrates With

  • Dips
  • UnWedge

+

Import joint locations and orientation data including set statistics from Dips. For mapped joints, you can import the orientation and location of each defect.

When boreholes or scanlines are available, analyze joint set statistics in Dips, then import the mean dip, dip direction, and Fisher K to define synthetic joint sets in RocTunnel3.

RocTunnel3

+

Import model geometry, properties, and joints from UnWedge to fully define your model.

The Latest Features

  • Borehole Manager

    Easily construct complex stratigraphy and groundwater tables using the built-in borehole manager and locational borehole data. Various interpolation methods are available to best represent field conditions.

  • Support Design

    Apply and remove bolts, shotcrete, and support pressures in stages, and assess required support capacities and extents for every construction stage.

    Various bolt types are available, and you can easily view critical bolts and force diagrams and apply design standards or design factors of safety.

  • Key Block Analysis

    Identify key blocks that control large failure extents and simulate the successive unravelling of the excavation as key blocks are detached.
