Mine collapse

Critical

⚠️ Check: Is the area safe for you to approach?

Tunnel collapses propagate — moving may trigger further roof fall.

Stay still. Cover mouth. Tap on metal. Save light. Call for help if signal works.

DEVELOPMENT FIXTURE — Do NOT light matches, lighters, or cigarettes — explosive gas risk.

DEVELOPMENT FIXTURE — Do NOT operate diesel equipment in sealed pocket — carbon monoxide kills.

DEVELOPMENT FIXTURE — Do NOT remove timber props unless trained — they hold the roof.

DEVELOPMENT FIXTURE — Do NOT shout unless rescuers are within direct earshot.

DEVELOPMENT FIXTURE — Use mine emergency communication if installed.
DEVELOPMENT FIXTURE — If phone reaches surface: call 112 — say mine name, level, and last known landmark.
DEVELOPMENT FIXTURE — Continue tapping on schedule so acoustic locators can triangulate.

Underground entrapment always needs specialized mine rescue.

DEVELOPMENT FIXTURE — Mine rescue teams need hours to days — conserve resources.
DEVELOPMENT FIXTURE — All rescued miners need medical evaluation for dust inhalation and crush injury.

This helper does not contact emergency services. You must call yourself.
