Environmental Geochemistry and Mine Drainage Management

After removal of the coal, open cast pits are backfilled with permeable spoil (waste rock) that can produce poor quality drainage

WATER IMPACTS OVER A WIDE AREA

Solution[H+] has been involved in dozens of projects to assess and manage the impact of coal mining on surface and groundwater resources.

Despite the threat of climate change, coal remains an important industrial feedstock and fuel. South Africa has a long history of exploiting its significant reserves of coal through underground and open cast mining methods. Vast volumes of rock have been exposed to air and water with drastic changes to their chemical stability. This has resulted in dissolved salts and acidity affecting rivers, wetlands, and groundwater.

Local coal miners generally appreciate the need to manage mine water quality. The challenge is to obtain meaningful geochemical sampling and analysis of the enormous volumes of material involved. Solution[H+] has helped many clients address this challenge.
