Broadmeadows uses the punch longwall mining method, accessing coal seams directly from the pit created by the original surface mine. While longwall operations began in 2005, Broadmeadows did not adopt LTCC technology until 2013. Today, the mine uses Cat longwall equipment and technologies to produce 4.5 million tonnes (4.9 million tons) of coal.
