Bord and pillar mining

Bord and pillar mining

This diagram shows the traditional method of bord and pillar mining. Miners extracted coal along roadways or bords, with the coal between the bords acting as pillars holding up the roof. The outer pillars were then mined, leaving the roof to collapse in a controlled way as the miners retreated towards the exit.
