Create Sedimentological and Structural Models to Assist in Identifying Geological Features That Impact on Mining

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.

by Mark Grodner | December 2001

What this report found

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.

What this report found

Co-treating coal discards with sewage sludge by hydrothermal carbonisation gave hydrochars with better physicochemical properties than treating either waste alone. The blended hydrochar reached a surface area of 20.35 m2/g and a pore volume of 0.38 cm3/g, and removed 97.19% of nevirapine and 93.32% of lamivudine from recycled water. Routes to activated carbon and hydrogen storage were also assessed.

Audit and Diagnostic Assessment of Productivity in Continuous Miner Sections

SGE Ashworth

2003

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.

What this report foundSection performance was limited by the will and motivation of the workforce, not by equipment, layout or technical competence, all of which were found sound.

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.

What this report found

Eutectic freeze crystallisation was compared with evaporative crystallisation as a route for treating hypersaline mine brine. Optimised commercial evaporative crystallisers use 40 to 50 kWh per cubic metre of feed. Laboratory work measured a eutectic temperature of -21.1 degrees Celsius for pure sodium chloride solution, and found that a large difference between coolant and solution caused scaling on the heat exchanger wall.
