What is Longwall Mining? (with pictures) - Info Bloom

30-01-2021  Longwall mining is a highly productive underground coal mining technique. Longwall mining machines consist of multiple coal shearers mounted on a series of self-advancing hydraulic ceiling supports. The entire process is mechanized. Longwall mining machines are about 800 feet (240 meters) in width and 5 to 10 feet (1.5 to 3 meters) tall.

Longwall Mining Method and Design

Longwall mines produce more than 30 pct of all underground coal, up from 5 pct just 15 years ago. The continued growth of longwall mining without appropriate multiple-seam planning may increase the cost and risk of mining. Optimization of the mine design factors is arguably the primary means for controlling interactions between operations.

Longwall Mining in Seams of Medium Thickness

In continuous mining, a machine known as a continuous miner cuts the coal from the mining face and deposits it directly into a haulage vehicle; an efficient technique that obviates the need for drilling and blasting. Room-and-pillar mining in low seams is generally less efficient than longwall mining because as much as 50% of coal is lost.
