Figure 1 – AEISG Test Temperature Plot for Sample ___
Figure 2 – AEISG Test Temperature Plot for Sample ___
Figure 3 – AEISG Test Temperature Plot for Sample ___
Figure 4 – Samples ___ and ___ contained a large amount of visible pyrite
Figure 5 – Samples ___ and ___ reacted violently when tested as per the QMR Reactive Ground
Figure 6 – Sample ___ under the microscope showed trace pyrite
Under a microscope all samples were confirmed to contain pyrite (refer to Figure 4 and Figure 7). Prior to testing as per the AEISG Code of Practice each sample was assessed for reactivity risk based on pH, carbonate and amount of reactive sulphide using the QMR Reactive Ground Test (refer to Table 1 and Table 2 for results of both tests). Testing as per the AEISG Code of Practice resulted in sample ___ testing as marginal and samples ___ and ___ as not reactive. The QMR Reactive Ground Test confirmed that sample ___ was not reactive as the sample had only trace sulphide content. The QMR Reactive Ground Test also identified coal was inhibiting a reaction in samples ___ and ___ and that these samples will spontaneously react if subjected to acidic conditions (refer to Appendix 1)
Conclusion:
Sample ___ was found to be marginal and samples ___ and ___ as not reactive when tested as per the AEISG Code of Practice. The QMR Reactive Ground Test confirmed sample ___ was not reactive and that samples ___ and ___ contain a significant amount of pyrite that is prevented from reacting by the coal that each sample contains (with sample ___ not having sufficient coal content to produce a not reactive test when tested as per the AEISG Code of Practice). Samples ___ and ___ will cause the spontaneous detonation of a blast hole in acidic conditions. (Refer to Appendix 1)
