Impact · The Coaltech Case Studies

Research that left the page and changed the mine

Since 1999 the coal industry has funded one shared research programme: ours. These are eighteen of the hundreds of projects the programme has funded, chosen for the depth of their impact on how mines run, close and clean up. Every claim traces to a published report in the open Library.

The case studies

A selection of eighteen, told the way they happened: the problem, the work, the proof. The full record of every funded project lives in the Research Library.

SURFACE ENVIRONMENT

We brought a poisoned wetland back to life

Eight years at Zaalklapspruit. The Dongalock innovation, the first diatom index for damaged wetlands, and water that cleans itself again.

2015 to 2023Read the case study →
SURFACE ENVIRONMENT

The standard the industry rehabilitates by

We commissioned the rewrite of the national rehabilitation guideline. Published 2019. On desks across the sector.

2017 to 2019Read the case study →
INTEGRATED MINING AND PROCESSING

Five phases to stop the spark underground

How ignitions start at a continuous miner’s cutting head, and the protocols that stop them.

2015 to 2020Read the case study →
SURFACE ENVIRONMENT

How to close a mine and walk away honestly

Pitlakes, relinquishment criteria and the risk models that make a closure plan defensible.

2018 to 2024Read the case study →
INTEGRATED MINING AND PROCESSING

Washing coal without water

We tested the world’s dry technologies on our own coals, then bought our own pilot plant.

2015 to 2024Read the case study →
SURFACE ENVIRONMENT

The water that outlives the mine

Brine frozen into clean water and salt. Treatment that runs where no plant can be staffed.

2012 to 2026Read the case study →
INTEGRATED MINING AND PROCESSING

The fire that needs no spark

Twenty years of sponcom science, ending in the guidelines opencast mines now run on.

2005 to 2025Read the case study →
FUTURE TECHNOLOGIES

The number the sector negotiates from

6.73 Mt CO2e, Scope 1 and 2. The baseline that turned an estimate into evidence.

2022 to 2026Read the case study →
INTEGRATED MINING AND PROCESSING

From discard dump to road surface

60 million tonnes of discard a year, reframed as feedstock: asphalt, building components, rare earths.

2021 to 2026Read the case study →
FUTURE TECHNOLOGIES

Cleaner fire: the HELE-CFB programme

From first studies to a R10 million, nationally co-funded localisation programme for IRP 2025.

2017 to 2026Read the case study →
SURFACE ENVIRONMENT

Farming with the water a mine leaves behind

Twenty years of trials. Crops and pastures growing safely on treated mine water.

2006 to 2023Read the case study →
INTEGRATED MINING AND PROCESSING

The formula that holds the roof up

The pillar strength database and the mapping of century-old workings nobody wrote down.

2011 to 2019Read the case study →
INTEGRATED MINING AND PROCESSING

The room that keeps a crew alive

Life-sustainability trials with crews inside the bay and the conditions measured.

2022 to 2025Read the case study →
INTEGRATED MINING AND PROCESSING

Blasting where the ground is already burning

The hot hole doctrine for opencast mines, and the instruments that find the heat first.

2020 to 2022Read the case study →
INTEGRATED MINING AND PROCESSING

The dust you cannot see

Honest sampling, masks that get worn, and the 2025 best practice guideline.

2019 to 2025Read the case study →
INTEGRATED MINING AND PROCESSING

The laboratory that studies explosions

We funded the upgrade of the national coal dust explosibility facility, completed 2025/26.

2024 to 2026Read the case study →
SURFACE ENVIRONMENT

Keeping soil alive while it waits

The stockpile science and the Soil Handbook: rehabilitation that starts on day one.

2016 to 2021Read the case study →
SURFACE ENVIRONMENT

Cattle on the discard dump’s doorstep

Kenaf grown in coal discard, regenerative farming on rehabilitated land, and the carbon counted.

2023 to 2026Read the case study →
