Task-Specific Postures in Low-Seam Underground Coal Mining

Of these mines, 148 (28%) were. considered low seam with a seam height of less than 109.2 cm and produced 19.1 million tons of coal. For economic reasons, the seam height of the coal corresponds with the working height (from mine floor to mine roof) of the mine. Thus, at least 6% of underground coal produced in the United States in 2009 came ...

(PDF) Method Extraction of Lower and Upper Coal Seam in ...

According to one formulae by Shevyakov, 1958, if the distance between the two seams is lesser than 12 h+3.5 h2 (h, being the height of the seams in metres) then there remains a chance ofunder-mining. If the seams are steep and the parting between them is small then even working in the upper seam may cause under mining in the lower seam.
