Mining Survey

0/6 steps
STEP 1

Underground Control

STEP 1 — ESTABLISH UNDERGROUND CONTROL
Set up control points in the mine.

Why we do this:
Underground surveys need their own control
network. Surface control isn't visible underground.

What you need:
• At least 2 control points per section
• Points in stable rock, not ore
• Permanent markers (pins, bolts)

In METARDU:
→ Create new project
→ Set survey type: Mining
→ Add control points as Primary
STEP 2

Instrument Setup

STEP 2 — SET UP IN TUNNEL
Position total station for inclined measurements.

Key points:
• Centre over control point
• Measure instrument height (HI)
• Account for tunnel clearance
• Ensure clear sight lines

For inclined traverses:
• Measure slope distance
• Measure vertical angle
• Measure horizontal angle
STEP 3

3D Traverse

STEP 3 — RUN INCLINED TRAVERSE
Measure between stations with full 3D data.

In METARDU Mining Tools:
→ Select 3D Traverse
→ Enter slope distance
→ Enter vertical angle (+ or -)
→ Enter horizontal bearing
→ Calculate 3D coordinates

Formula:
HD = SD × cos(VA)
VD = SD × sin(VA)
ΔE = HD × sin(bearing)
ΔN = HD × cos(bearing)
ΔZ = VD
STEP 4

Volume Calculation

STEP 4 — CALCULATE VOLUMES
Compute volumes from cross sections.

In METARDU Mining Tools:
→ Select Volume calculator
→ Choose method:
  - End Area (simple)
  - Prismoidal (accurate)
  - Cut/Fill (for earthworks)

Enter section areas at chainages.
STEP 5

Subsidence Monitoring

STEP 5 — MONITOR SUBSIDENCE
Track point movement over time.

In METARDU Mining Tools:
→ Select Subsidence Monitoring
→ Enter epoch 1 coordinates
→ Enter epoch 2 coordinates
→ Calculate 3D movement

Track:
• Vertical settlement (ΔZ)
• Horizontal movement (ΔE, ΔN)
• Total 3D displacement
STEP 6

Generate Report

STEP 6 — MINING SURVEY REPORT
Document your survey results.

Include:
• Traverse calculations
• Volume computations
• Subsidence data
• Control point coordinates
