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
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.

Coal can feed products well beyond combustion. The study sets out routes to rare earth elements held in particular seams, building materials made with carbon fibre and carbon char, coal foam and graphene composites, carbon black and activated carbon, including a coal derived activated carbon reported to hold four times the gas of compressed natural gas at lower pressure.
Audit and Diagnostic Assessment of Productivity in Continuous Miner Sections
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.

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.
Simulation of Regional Collapses in Bord & Pillar Workings

Three dimensional modelling of a documented subsidence event in the Witbank coalfield, aimed at reserves in the seam above old workings that current pillar strength formulae sterilise.

Finite element simulation reproduced the rapid collapse of bord and pillar workings in the 2 Seam at a Witbank colliery, showing that progressive pillar deterioration triggers snap through of a strong sandstone plate in the overburden. Too little was known about the chosen collapse to back out a real pillar safety factor, so the calibration goal was not met.
