Work to secure a mine shaft in Gosforth, Newcastle upon Tyne, has been completed.

The Coal Authority carried out the essential works to make the mine shaft safe for residents, which caused a ground collapse near homes and garages in the area.

The team designed a permanent solution which required over 65 cubic metres of reinforced concrete to repair an area in Craster Square which collapsed at the end of last year.


Tim Marples, Head of Public Safety and Subsidence at the Coal Authority, said: "When the ground collapse occurred we immediately fenced off the area and filled the void to make it safe.

"We then carried out ground investigations which included drilling boreholes to investigate the mine shaft's structure and fill materials, as well as the conditions underground.

"We've completed the construction of a hexagonal, steel reinforced concrete slab to cover the mine shaft, which now sits two metres below the ground.

"Underneath it we've injected 35 cubic metres of resin grout into the shaft to ensure the area is completely stabilised.

"This approach means that the mine shaft is now safe and local residents are protected."
