Basic Technical

Void Space Geometry Mapping

noun

Pronunciation: /vɔɪd speɪs dʒiˈɒmətri ˈmæpɪŋ/

The process of accurately documenting and measuring underground voids, cavities, and excavated areas within abandoned mines using survey techniques and geophysical methods. This mapping is essential for determining backfill requirements, stability risks, and resource allocation in reclamation planning.

Plain English

Measuring and mapping empty spaces underground in abandoned mines to plan how to fill them during reclamation.

Etymology & History

Origin languageEnglish-Greek hybrid

Rootvoid (from Latin voidus, empty) + space (from Latin spatium) + geometry (from Greek geometria, measurement of earth) + mapping (from Old French mape, cloth/map)

First recorded use1990s

Usage frequencyUncommon

Usage

"Void space geometry mapping using 3D laser scanning identified 2.3 million cubic meters of underground voids requiring backfill material."

Style guide notes: Use full phrase in initial mentions; acceptable to shorten to 'void mapping' in subsequent references within same document.
