Watch Collapsed Mines Re-Shape in Real Time

EchoQuilt builds a live navigable 3D quilt of the underground from passive crew sound and footstep vibration — current with every roof shift and pillar slump.

A roof collapses 1,200 feet down a coal seam at 2:47 AM. By 3:15, the original survey is already wrong — pillars have shifted, voids have filled with rubble, and the rescue squad is staring at a map of a mine that no longer exists. EchoQuilt re-maps the affected workings in twenty minutes from passive squad breathing, boot-strikes, and tool vibration the team is already generating. Incident command at the portal sees the new geometry on a tablet before the first breathing-apparatus crew reaches the working face. Trapped-miner voice calls and pipe-tap signals get triangulated against the live quilt, narrowing the search radius from a 200-foot cross-cut to a specific chute.
