Coal Mining Risk Assessment for Erection of Two Dwellings, Loxley New Road, Sheffield

Case Study Reference: 15-11-04

Planning Authority: Sheffield City Council

Planning Reference: 15/04051/FUL

Synopsis:

As the site was within an area where coal measures had the potential to cause surface instability a Coal Mining Risk Assessment was required to support the planning application for the erection of two dwelling on the site.

As part of the desk based assessment a Coal Authority report was procured for the site as well as the large scale geological map. Coal Authority maps for Sheffield City Council were also reviewed as part of the desk based assessment.

Whilst the Coal Authority data indicated there were no worked shallow seams under the site, the site was in an area where coal was close to or st the surface. The large scale geological map identified two outcropping coal seams within 20m of the site which may be present at depths of less than 10mbgl the site.

Given there was a potential risk of surface instability intrusive works were proposed once planning had been granted.

Both the Coal Mining Risk Assessment and the memo accepting the assessment are given with the documents associated with 15/04051/FUL.
