The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support. Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive.

From Shovels to Machines West Virginia
At first, machines helped miners load more coal; eventually, they put the majority of miners out of work. Beginning in the late 1940s, coal companies rapidly introduced longwall and continuous mining machines. Longwall machines sheer coal from the face in a circular motion. The broken coal falls into a pan line, which leads to a conveyor belt

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.
