Coalsnaughton mine subsidence demolitions: geotechnical lessons for engineers
Reviewed by Tom Sullivan

First reported on New Civil Engineer
30 Second Briefing
Homes on Benbuck View and Dunmoss View in Coalsnaughton, Clackmannanshire are to be demolished after Mining Remediation Authority investigations confirmed historic underground workings had caused active mine subsidence beneath the two streets. The decision follows visible ground movement reported on 18 May and subsequent detailed geotechnical assessments that ruled out practical stabilisation options for the affected plots. Engineers will now need to manage demolition, backfilling and long-term ground monitoring, with implications for foundations and service corridors on adjacent properties built over former coal measures.
Technical Brief
- Demolition sequencing must avoid surcharge loading on actively subsiding zones and protect adjacent foundations and services.
- Backfilling strategy will need to address both shallow voids and potential crown-holes above deeper galleries.
- Service corridors (water, gas, drainage) require rerouting or flexible connections to accommodate ongoing ground strain.
- For similar coalfield settlements, early integration of subsidence risk into planning and foundation selection is a key lesson.
Our Take
The Mining Remediation Authority also appears in a recent four-year, £9.4M professional services framework in our database, signalling that incidents like the Coalsnaughton subsidence are feeding into a more formalised national pipeline of legacy mine risk work in the UK.
In our Hazards coverage, the Mining Remediation Authority is more often associated with water-quality and stabilisation work at legacy metal mines in Wales (e.g. Nant y Mwyn lead mine) than with direct impacts on residential streets, so the Coalsnaughton case underlines how coal-era voids are now a front-line issue for built-environment safety.
