Work to fill large sinkhole at farm complete

Excavation work was carried out after the sinkhole was discovered

Safety works have been completed in a farm in Derbyshire after a 3m (9.8ft) deep sinkhole was discovered in May.

The Mining Remediation Authority said it was called after the surface hazard - which measured about 4m (13.1ft) in diameter - was found in a field in Stretton.

According to the authority, records suggested the collapse was over a shallow roadway leading from a historical mine entry to the abandoned Strathfield colliery.

It said the area was excavated and large stone was pushed into the roadway before the void was filled.

Following the excavation, a layer of fabric and mesh was laid

Project manager Rob Pilmore said ground investigation works took place in August to give time for the grass in the rest of the field to grow.

Following the excavation, a layer of fabric and mesh was laid about one metre below ground level, before the field was reinstated and seeded.

The field was then reinstated and seeded
