Maximising coal recovery in challenging geologies represents a significant efficiency opportunity for most coal mining operations to increase the value of their resource. As the easy coal is mined out, mine operators need to become more skillful at mining thin, steep, deep and undulating seams productively and without sacrificing coal quality.
