Implementation of the coal resource development pathway


Groundwater extraction from seven of the mines included in the coal resource development pathway (CRDP) for the Galilee subregion has been explicitly modelled by the groundwater analytic element model (GW AEM).

Anticipated groundwater production rates for mines were obtained from relevant environmental impact statements and applied to digitised polygons that represent the active mine working areas. To simulate dewatering of alluvial sediments proximal to mine pits, a constant head of –10 m was applied along the boundary of each mine footprint, representing complete dewatering of the Cenozoic and alluvial deposits.

The Galilee subregion CRDP consists of 17 proposed new coal and coal seam gas (CSG) resource development projects (see companion product 2.3 for the Galilee subregion (Evans et al., 2018b)). Of these, only seven coal resource developments included in the modelled CRDP are incorporated into the GW AEM as they had sufficient information for modelling (Table 12). As there are no baseline coal resource developments in the Galilee subregion, the CRDP is defined only by the additional coal resource developments.
