Review of Current and Expected Underground Coal Mining Methods and an Evaluation of the Best Practices Associated with These
Review of underground coal production systems in South Africa set against practice in Australia, China and the United States, with guidance on equipment choice and section planning.
by André William Dougall | 2010
South African underground sections average about 60 000 t a month, against 130 000 to 160 000 t for single pass bolter miner units on continuous haulage, while the better sections target 1.4 to 1.6 Mt a year. Australian longwalls deliver 5 to 7 Mt a year from one face, compared with 3 to 5 Mt at the two local wall operations.
