A coal authority mining report identifies the environmental and stability risk arising from any past, current and future underground and surface coal mining activity that affects a property. 

This includes information on mineshafts, subsidence claims, reported hazards and mine gas emissions.

Coal authority mining reports in England and Wales also include information from the Cheshire Brine Subsidence Compensation Board (CBSCB) identifying if the property has been the subject of a claim for subsidence damage caused by brine extraction.


Bristol Coal Mining Archives’ reports are based on the extensive archive built up over many years by the late John Cornwell, who obtained information from both public and private sources. 

BCA holds the most extensive collection of such information for Bristol, South Gloucestershire and Somerset. 

The collection comprises early maps, plans and other archive material covering coalmining and other past industrial activity.

The reports are divided into five sections:

  • past mining activity 
  • shafts and adits 
  • water and drainage levels 
  • surface geology 
  • subsidence.

The postcodes areas in which we operate fall within this coalfield are all of those for Bristol (BS), parts of South Gloucestershire (GL) and those for parts of Bath (BA) in particular the following: BS1, BS2, BS3, BS4, BS5, BS10, BS11, BS13, BS14, BS15, BS16, BS20, BS30, BS31, BS32, BS34, BS36, BS37, BS39, BS40, BS41, BS48 and some parts of BA1, BA2 and BA3.
