What this report found

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.

What this report found

Three modes of intervention were found in coal company procurement: preferential procurement rules, segmentation of goods and services by suitability for transformation, and support programmes for small suppliers. Progress stalled where supplier development was handled by staff carrying other duties, since work not tied to production loses time and has no target. The remedy proposed is procurement targets linked down through commercial and production management.
