Appendix A Diagrams of causal pathways

Figure 15 to Figure 20 represent the causal pathways for hazards by identifying the activities, impact causes and impact modes for open-cut and underground coal mines and coal seam gas (CSG) operations. These were developed for the Maranoa-Balonne-Condamine subregion initially (Holland et al., 2016) but are generically useful across all subregions and bioregions. The hazard handling or scope discussed in Section 3.1 .3.1.1 is not considered in this representation. Collectively Figure 15 to Figure 20 graphically represent the hazard spreadsheets arising from the Impact Modes and Effects Analysis (IMEA) and allow many hazards and their natural groupings to be visualised simultaneously.

See Holland et al. (2016) for full explanation and interpretation of the final results, which might vary from that shown in these figures. Impact causes are underlined, impact modes are bold and activities are bullet points. Arrows indicate the spatial context for each hazard: aquifers, aquifer outcrop areas, watercourses, catchments. Hydrological effects to system components may cause potential impacts to assets or ecosystems that rely on surface water and/or groundwater. Hydrological effects are denoted by the round circles, where the light blue circles represent surface water hydrological effects and the dark blue circles represent groundwater hydrological effects. The system components are represented by the light blue triangle, grey oval and dark blue rectangle.
