Drift Mining, Mining Process, Mining Techniques, Gold, Zinc,
Drift Mining. Drift mining is a process of accessing precious geological material, like coal, by cutting into the side of the earth, rather than tunneling directly downwards. Drift mines have flat entries into the coal seam from a hillside. Drift mines are different from slope mines, which have a tending opening from the surface to the coal vein.
