Machines Used in Coal Mining Career Trend

Nov 28, 2018  For extracting coal which lies close the surface, huge drag-line shovel machines remove the topmost layers of soil and rock, exposing the coal, which is then removed by smaller machines. Surface mining may involve removing sections of hills or top layers of a flat surface area. The layers of rock and dirt covering the coal are reserved for ...

Brief History of Mining Advancement of Mining Technology ...

Coal mining . Some coal mining began before 1900, but the most productive coal mining techniques didn’t develop until after the turn of the century, including the first conveyor belt and mechanized coal loading. Bituminous coal overtook anthracite in the mid-1800s. In the 1960s, smaller coal companies merged into larger, more diversified firms.
