YANZHOU COALMINING CO. Longwall top coal caving technology at North Goonyella mine

摘要

Peabody Energy has announced a new licensing agreement with Yanzhou Coal Mining Co. for the installation of its longwall top coal caving (LTCC) technology to enhance recovery of metallurgical coal at Peabody's North Goonyella mine in the Bowen basin, Australia. Yanzhou is a subsidiary of Yankuang Group Co. Ltd. Peabody estimates the new technology will allow the recovery of up to 3.9 million t of additional high quality metallurgical coal from the mine, with opportunities for future use in other areas. LTCC technology improves the recoverability of coal over traditional longwall mining methods and will allow the operation to mine the full coal seam thickness of 6.5 m versus the conventional longwall mining method of 4.2 m.
