A » Longwall mining is an efficient coal extraction method where a long wall of coal is mined in a single slice, typically using a shearing machine. Hydraulic supports hold up the roof temporarily as coal is removed, allowing for continuous operation. The process enhances safety and productivity by automating coal cutting and requires less manual labor, effectively extracting large quantities of coal from underground seams.

A »Longwall mining involves extracting coal or other minerals from a long, continuous wall of rock. A shearer cuts the coal, which falls onto a conveyor belt. Hydraulic supports advance as mining progresses, allowing the roof to collapse behind. This method is efficient for large, uniform deposits, maximizing extraction while minimizing waste.
