High-extraction retreat mining is a form of room-and-pillar mining that extracts most of the coal. Rooms and pillars are developed in the panels, and the pillars are then systematically removed (fig. 1F). In early (pre-1960) longwall mines, mining advanced in multiple directions from a central shaft (fig. 1G).
