What this report found

Builds on an earlier productivity audit that identified fluctuating bonuses and incentives as an influence on output, safety and employee stress. The work examines how salaries, production bonuses and safety bonuses are graded and distributed across employee categories, how workers perceive that distribution, and whether incentives in practice motivate production and safe working. Stress and morale are treated as measures of wellbeing.

Dry Processing of Coal – Progress Report: Tests Conducted on the IMS / Slater Coal Marketing Allair Dry Jig

GJ de Korte

2016

Test work on a dry jig installed at a Balmoral site, covering coal sized below 50 mm and duff below 12 mm, for producers considering waterless beneficiation.

What this report foundA 30 tonne per hour pilot Allair dry jig upgraded run of mine coal to thermal coal specification, but could not effectively beneficiate finer duff.

What this report found

A 30 tonne per hour pilot Allair dry jig upgraded run of mine coal to thermal coal specification, but could not effectively beneficiate finer duff. Cut point densities and EPM values matched other dry processing equipment, though the jig appeared to give better control of the parameters governing separation. Four tests ran on run of mine coal and two on duff.

What this report found

Stockpiling degraded every soil property measured across four Witbank area mines. Clay content of topsoil and subsoil rose by 50 to 60 per cent, surface bulk density increased from stockpiling through to rehabilitation, and effective depth on rehabilitated areas was under 17 cm in most cases. Topsoil organic carbon fell by almost half and microbial species numbers dropped in the stockpiles.
