Table 1 - Results for Testing using the AEISG Code of Practice
Table 2 - Results for Testing using the QMR Reactive Ground Test
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). One samples, SP-RG5 contained more than trace level of reactive sulphide of 2.2%. The pH of sample SP-RG5 was 7 and at this level of pH the coal also contained in the sample inhibited a reaction when tested as per the AEISG Code of Practive.
Conclusion:
All samples were found to be not reactive when tested as per the AEISG Code of Practice and QMR Reactive Ground Test.
