Tyne and Wear HER(5919): Newcastle, Nuns Moor, pillar-and-stall mine shaft - Details
Newcastle, Nuns Moor, pillar-and-stall mine shaft
Mine Drainage and Ventilation Site
An amorphous raised mound measuring 30 metres by 22 metres with a central depression which is 10 metres in diameter and 1 metres deep. There are traces of coal in surrounding rabbit scrapes. The use of pillar-and-stall mining (cutting horizontal headings out of the bottom of the shaft, leaving pillars of coal to support the roof) meant shafts could be spaced wider apart. The best example of a widely spaced grid pattern of shafts on the Town Moor is on Nuns Moor, where four shaft heads form a square pattern. These shaft heads have larger spoil heaps than the Bell Pits, indicating deeper shafts and a later mining episode. A diagnostic feature of the landscape indicating pillar-and-stall mining is the subsidence of the surrounding ground surface, due to the caving in of the galleries especially after the removal of the roof supports. Such areas of mining subsidence effect large areas of the Moor.
