Longwall mining is a highly productive underground coal mining method that involves the extraction of a long wall of coal in a single, continuous operation. This animation shows longwall equipment in a coal mining operation. Longwall mining is known for its efficiency and high production rates but can have significant environmental and subsidence impacts. Proper engineering and safety measures are essential to minimise these impacts and ensure the safety of miners and the surrounding environment
