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.
