Products

Stability, rock structure and runout in one suite.

Each tool answers a specific ground engineering question, from the critical slip surface to where falling rock comes to rest.

Slope stability

JSlope

Assess slope stability and compare design options.

  • Find critical slip surfaces and factors of safety.
  • Compare groundwater, loading and reinforcement cases.
  • Cut sections from 3D terrain, with no mining CAD.

Rockfall and runout

JRunout

Assess where falling rocks and failed material could travel.

  • Review trajectories and runout distances.
  • Check impact energies at barriers.
  • Compare berms and protection layouts.

Rock slope kinematics

JStereonet

Interpret joint orientations and assess rock slope failure modes.

  • Plot orientations and identify structural sets.
  • Assess planar, wedge and toppling failures.
  • Explore discrete fracture networks in 3D.

Rock wedge stability

JWedge

Assess rock wedges and planar failures, then compare support options.

  • Review surface wedges and planar sliding.
  • Assess underground openings and intersections.
  • Compare joint sets, loads and rock-bolt support.

Rock strength and lab data

JLab

Fit strength parameters to test data and compare failure envelopes.

  • Compare material strength criteria.
  • Calibrate parameters against laboratory results.
  • Export charts and engineering reports.

Geological mapping

JMapper

Map discontinuities on textured rock surfaces and interpret their orientations.

  • Import and calibrate textured OBJ models.
  • Link surface measurements with an equal-angle stereonet.
  • Analyse structural sets, spacing and trace lengths.

Radar monitoring coverage

JRadar

Compare radar positions and identify visible ground, blind spots and displacement sensitivity.

  • Import terrain and place monitoring radars.
  • Inspect visibility, vector loss and nominal pixel width.
  • Save terrain and radar configurations in portable projects.

3D voxel-based runout

JVoxel

Map potential failure masses and inspect their simulated deposition on terrain.

  • Map finite release surfaces and identify enclosed masses.
  • Compare voxel deposition, thickness and travel distance.
  • Save complete terrain studies in portable projects.

How engineers use it

From section to decision.

The same four steps whether you are checking a road cut, a pit wall or a rockfall barrier.

  1. 01

    Section

    Draw the section or cut it from 3D terrain in JSlope, with no mining CAD step, then assign materials and groundwater.

  2. 02

    Analyse

    Search for the critical slip surface, trace rockfall paths or check kinematic failure modes, on your workstation or in the cloud.

  3. 03

    Compare

    Run design cases side by side: groundwater, loading, reinforcement, berms and barriers.

  4. 04

    Report

    Print the views and tables that document the decision for review.

JSlope in use

The section, the search and the result in one view.

Draw the geometry, assign materials and groundwater, then review the critical surface and compare design cases without leaving the viewport.

JSlope results view of a highwall and lowwall section with thousands of trial slip surfaces, the critical surface divided into slices, the water table and the results panel.
Critical surfaceA non-circular search through a highwall and lowwall section: every trial surface, the critical surface with its slices, and the water table.
JSlope zoomed onto one slice of the critical surface, labelled with its weight, inter-slice, normal, shear and pore-pressure forces.
Slice forcesWeight, inter-slice, base and pore-pressure forces on one slice of the critical surface.

JSlope 3D import

From terrain to section, and back into 3D.

Place imported terrain on the globe, cut sections where they matter, and review each analysed section on its plane in the terrain.

Sections from terrainNominate a section across imported terrain and preview its profile before building the 2D model.

Spatial workspacePlace the model on the globe: its coordinate system, site extent, local origin and grid bearing.
