Audit and Diagnostic Assessment of Productivity in Continuous Miner Sections

SGE Ashworth

Mine level study of the human and social influences on continuous miner section output, using interviews, focus groups, observation and work study at participating collieries, for mine managers.

by SGE Ashworth | February 2003

What this report found

Section performance was limited by the will and motivation of the workforce, not by equipment, layout or technical competence, all of which were found sound. Team based bonus payments were the strongest motivator and reinforced cooperation across shifts and functions, but dependence on bonus income to meet monthly expenses turned it into a source of stress. Recognition in front of colleagues and family motivated strongly.

Consolidated review of six field studies on highveld opencast rehabilitation, covering soil profiles, pasture performance, crop potential and soil water, for mine environmental staff and regulators.

What this report foundRehabilitated opencast soils carried pastures and cash crops, but compaction and cover soil depth set the ceiling on what they could produce.

What this report found

Rehabilitated opencast soils carried pastures and cash crops, but compaction and cover soil depth set the ceiling on what they could produce. Only land with deep cover soils suited maize and sunflower, and deep ripping with regular tillage was needed. Bulk density standards were not met at the trial sites, which the review judged enough to have changed the results.

What this report found

Sets out the steps to establish a small scale coal mine in South Africa, from mineral rights and regulatory approvals through finance, mining and processing choices, marketing, and environmental management and closure. The information a new entrant needs sits in many separate places, so the guideline draws it together from practitioners rather than from any single published source.
