Namoi Existing Mine Development Surface Water Footprints

Abstract

The dataset was derived by the Bioregional Assessment Programme from a source dataset. The source dataset is identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.

The Namoi Existing Mine Development Surface Water Footprints represents the area in a mine site that impacts surface runoff through interception preventing its entry to the natural stream network. The footprints includes the entire area disturbed by coal mine operations, including mine pits, roads, spoil dumps, water storages and infrastructure. It may also include otherwise undisturbed parts of the landscape from which natural runoff is drained into mine-disturbed areas or retained in reservoirs. As new parts of the mine lease areas are opened up and rehabilitated areas established, the footprint changes over the life of a mine's operation.

This dataset includes the surface water mine footprints data for the Boggabri and Tarrawonga mines in the Namoi subregion.

Note: A footprint of the Canyon mine is also included, although this was not used in the modelling.

Purpose

To determine the mine areas affecting surface water runoff for use in the Namoi surface water modelling.

Dataset History

Footprints data for Boggabri, Canyon and Tarrawonga baseline mines were supplied by the NSW Department of Trade and Investment, Regional Infrastructure and Services and have been registered as a separate dataset: Historical Mining Footprints DTIRIS NAM 20150914. The areas covered by these files are the mine pit and support facilities from 2006 to 2012.

From this dataset Kmz files have been generated to enable cross-checking of the footprints to images on Google Earth, with modifications made if required. Files with GE in the file name have been digitised from Google Earth.

The Canyon mine is already in maintenance and is no longer being actively mined. This mine was not included in the modelling, but is kept here for completeness.
