    How It WorksAutonomous OperationLTCC Around The WorldA Productive AlternativeLongwall Top-Coal Cavingisn’t just an alternative mining technique; it can be the difference between a productive, profitable mine and an unsustainable operation. The technology reduces waste and operating costs, making for a more efficient operation. “By achieving the highest productivity possible, operations can stay profitable even in difficult economic times,” says Mundry. “And compared to other methods of high-face longwall mining, LTCC technology improves mine safety.”
