Mining Global published several infographics to give a visual perspective on the different types of coal mining. The article takes a look at surface/opencast, room & pillar and longwall mining.

As quoted in the publication:

The preferred choice in underground coal mining is the Longwall technique which accounts for roughly 301 percent of all underground coal production. This process involves a cutting head that moves back and forth across a panel of coal. Once cut, the coal falls onto a flexible conveyor for removal. This method is conducted under hydraulic roof support that advances as the seam is cut.
