Coal mining World Coal Association
In room-and-pillar mining, coal deposits are mined by cutting a network of ‘rooms’ into the coal seam and leaving behind ‘pillars’ of coal to support the roof of the mine. These pillars can be up to 40% of the total coal in the seam although this coal can sometimes be recovered at a later stage. Longwall.

The Work of a Coal Miner in the Gilded Age and Progressive Era
The first and the most laborious part of the work of coal digging consists in undermining, or bearing in, or holing the rooms. This is generally performed in the bottom of the coal seam with the pick. An undermining is made of varying depth-sometimes three to four feet, frequently five to six feet; the miner stands upon his feet and strikes

About the Coal Industry
The majority of Canada’s coal is produced by surface mining either strip mining or open pit. Strip mining is only a temporary use of the land and reclamation can be carried out at the same time mining takes place. With open pit mining, once the pit is mined it’s backfilled with earth and resurfaced with native trees, shrubs and grasses.
