The coal seams came to outcrop although the actual coal seam outcrop was generally covered by soil. The No 2 seam was a particularly important horizon and is between 5 and 6 m thick. Only the lower 2 to 3 m was mined as the rest was considered of too low quality. .
Coal seams are relatively thick and close to the surface, which allows for lowcost mining; a quarter of South Africa's bituminous coal is between 1550 m below the surface and much of the remainder between 50200m. Half of reserves are in seams 46m thick and a further third in 24m seams (Petrick Commission, 1975).
"Low coal seam" means "the coal seam which the thickness less than meters." Nowadays, there are several countries doing this research and test about steeply inclined low coal seam mining technology, but the result is not ideal. Fortunately, this problem was resolved by Chongqing Energy Group recently.

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. This can be achieved in what is known as 'retreat mining', where coal is mined from the pillars as workers retreat. The roof is
