Grazing trials on tall fescue pasture irrigated with gypsiferous mine water on rehabilitated mined land, run over several seasons. The work covers steer stocking rates, dry matter intake by cattle, and the factors that control pasture quality and intake, among them nitrogen fertilisation, stage of growth, sward structure and grazing intensity. Findings are reported study by study.

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.
Create Sedimentological and Structural Models to Assist in Identifying Geological Features That Impact on Mining
2001
Regional geology mapped in three dimensions from borehole data supplied by three mining groups, built for mine geologists and planners assessing seam disruption before layout design.

A three dimensional model of the northern Witbank and Highveld coalfield was built from more than 1100 borehole logs, with strata sorted into 13 major groupings and surface topography taken from satellite elevation data. It runs on open source visualisation software rather than a commercial package. Delays limited coverage to about a quarter of the coalfield.
