Structural mapping workflow for underground mining and tunnelling

Capture structural observations at the face and share them across engineering teams from the first scan to the final decision.

The decision structural mapping serves

Structural mapping informs how the ground will behave. Every excavation plan, support design, and sequencing decision depends on understanding what structures are present, where they are, and how they're oriented.

When structural documentation is incomplete or arrives late engineers fill the gap with assumptions. Those assumptions carry risk into every decision that follows.

Structural mapping

How structural mapping works today

Most structural observations still start on paper or in photos with minimal spatial context. Orientation data is estimated, not measured. Observations are transcribed into spreadsheets or modelling software manually and every transcription step loses detail.

By the time a structural model is updated, the face has moved on. The geological record is always catching up. Teams reviewing conditions are working with yesterday's data to make today's decisions.

The result: engineering decisions that should be based on structural evidence are based on structural interpretation filtered through multiple handoffs and an outdated model.

The Workflow Stages

How it works with GroundedAI

Five stages. Two products. One connected workflow from underground to decision.

STAGE 1 - PLAN - LITHOS

Define structural capture requirements

Set which features need to be mapped per zone, what classification system applies, and who reviews the data. Strata holds the capture protocol so every field team works from the same brief.

Stage 2 - Capture - Lithos

Scan and annotate at the face

At the face, scan and annotate structural features directly on the iPad. Record discontinuity orientation, persistence, spacing, and surface conditions. Lithos works offline underground data syncs automatically when connectivity returns.

Stage 3 - Map - Strata

Map and classify structures

Captured observations are georeferenced and structured into a 3D model. Strata classifies features by type, filters by zone or cycle, and builds the cumulative structural record that grows with the project.

Stage 4 - DECIDE - STRATA

Review structural interpretations

Engineering teams review structural data in Strata with full spatial context. Compare current conditions to the geological model. Identify patterns, anomalies, or changes that affect excavation planning or support design. Document the decision.

Stage 5 - SHARE

Export to downstream systems

Export structural datasets to modelling software Leapfrog, Deswik, or open formats (DXF, CSV). Generate reports for design reviews, regulatory submissions, or project documentation.

The Platform

How Lithos and Strata support structural mapping

Lithos · Field capture

Capture structural features at the face

Scan and annotate structural features directly underground. Measure discontinuity orientation with 3D spatial accuracy. Classify features using project-defined systems.

Capture offline. Every observation is time-stamped, georeferenced, and attributed to a specific location and cycle. The capture record is immutable.

What was observed, when, and by whom preserved from the moment of scan.
Strata · Data management

Structure and share the geological record

Every captured observation arrives with its spatial context intact. Classify, filter, and organize structural features across the entire project. Build the cumulative model that engineering teams reference for every downstream decision.

Review captured conditions as soon as they're synced not hours or days later.

The structural record that grows with the project accessible to every team that needs it.

Frequently asked questions.

Data captured in Lithos flows directly into the Grounded platform, where teams can review conditions, generate reports, and align on decisions.
