Coal Mining Encyclopedia of Alabama

Mining operations generally followed the pattern established in other coal regions, with drift, shaft, and slope mines being the most typical types. In drift mines, miners dug into outcroppings and followed coal seams along a relatively level path. These mines were easy to navigate but produced relatively little coal. Slopes, although somewhat deeper than drifts, also offered access to coal ...
