Mine Dewatering In Arid, Saline Environments In Western Australia: The Response Of Biota Emerging From Rehydrated Sediments, Charelle Harkins

Theses : Honours

Mine dewatering is a critical part of the mining process to prevent flooding of underground or open pits, to allow for the excavation of the available resources. Groundwater is abstracted from underground pits to the surface through extraction bores. The issue of where to discharge the excess water is a major concern. The use of natural wetlands is one option for mine water discharge. Saline lakes in arid areas are ideal receiving environments for discharge options, acting as evaporation facilities for the storage and disposal of excess mine water. Mine water discharge into ephemeral lake systems modifies the volume of …
