This paper explores the applicability of this framework for high-dump situations for a range of coal mine spoils. This is achieved by comparing their framework-assigned strength envelopes with direct measurements of their strength obtained from a custom-built large direct shear machine (LDSM). The machine can test at a much larger scale, in terms of combined specimen size (720mm x 720mm x 600mm) and stress (s’n up to 4.6MPa) than has ever been achieved using a direct shear machine for geotechnical testing of rockfill. A critical outcome is that the LDSM data highlights several non-compliant mine spoils, and stress-dependent shearing behaviour, for which correct application of the published framework will not provide reliable shear strength parameters for design.]]> Mon 07 Nov 2022 16:30:53 AEDT ]]>
