  • Longwall innovations to debut - Australian Mining

    DBT has built Australia's first Longwall Top Coal Caving (LTCC) system at the AUSTAR mine in the Hunter Valley. The LTCC shield on display — like the ones in service in the mine — allows mining to the total seam height of up to 8 m by using a longwall shearer to cut the bottom 2.8-3 m and then caving the top coal.
