The horizontal retort process was the dominant one for a very long time. It is now mostly replaced by the vertical continuous retort process (Rosenqvist, 1974). In the horizontal retort process the retorts are first charged with a loose mixture of ZnO and an excess of coke breeze and then heated to a maximum temperature of 1400°C (2552°F) to ...
This is known as "room and pillar" mining. When most of the coal seam has been extracted, the pillars then are mined one by one, allowing the roof to naturally cave in. Longwall Miner. Twenty percent to 30 percent of mined coal underground is from longwall mining. This is performed by a mechanical cutter that shears coal off from a panel on the ...
