ITS and UCS Tests on Rock Cores

Indicative Funding
$7,130
Summary
The rock cores will be provided by Mt Carlton. They will be cut to length to diameter ratios of 2.5 and 0.5 for the uniaxial compressive strength test and indirect ensile strength tests, respectively. The UCS tests involved developing stress-strain plots and determining the uniaxial compressive strength and the Young's modulus. The indirect tensile strength requires the determination of the Is values. The client will be provided with a report that includes all results and photographs of the failure specimens.

UCS, Indirect Tensile Strength and 3-Point Beam Tests on MIM Paste

Indicative Funding
$129,900
Summary
JCU is requested to carry out an extensive series of different tests on 50 mm dia. X 100 mm cylindrical specimens prepared and cured in the geomechanics laboratory. The tests will be in three stages, covering the three different solid contents 74.5%, 76.5% and 77.5%. The tests include uniaxial compression tests, indirect tensile strength and three-point bending. For each mix, slump tests have to be carried out at the beginning, to develop the slump height versus solid content variation.

Mix Designs for Paste Aggregate Fills

Indicative Funding
$20,725
Summary
JCU is requested to prepare the paste aggregate fill (PAF) samples, mixed with tailings in three different proportions. The samples are approximately 200mm diameter and 400mm in length, and the PAF should exclude fractions larger than 20mm and those less than 1.18mm. In all three mixes, UCS tests will be carried out after 7, 14, 28, 56 and 100 days and strength and Young's modulus will be determined. In addition, the grain size distribution, specific gravity, bulk density, and moisture content will be determined. In addition, it is also required to carry out slump tests on the different mixes using the standard slump cone.

Uniaxial Compressive Strength of Cemented Rockfills

Indicative Funding
$5,000
Summary
The Senior Mine Geotechnical Engineer, Mr Daniel Hill (0403492577 Daniel.Hill@evolutionmining.com) will prepare six 300mm diameter and 600 mm long cemented rock fill specimens that have to be studied for uniaxial compressive strength. The stress-strain plots will be developed to determine the uniaxial strength and the Young's modulus for each specimen. Prior to test, the sample ends will be flattened by Townsville Concrete Sawing and the cost (Approximately $700) will be paid by JCU. In additional to the cemented rock fill samples, 19 cement grout samples (50mm dia x 100 mm) will be tested.

Strength Study of Paste Aggregate Fill from Lady Loretta Mine

Indicative Funding
$18,415
Summary
The main focus is to cast thirteen 200 mm diameter x 400 mm long specimens and carry out uniaxial compressive strength, thus developing complete stress-strain plots from which uniaxial compressive strength and Young's modulus will be determined. On each of the 13 mix, slump test will be carried out, and dry density will be determined. Nine of the samples will be PAF and the remaining four will only contain tailings with binder. Grain size distributions and the specific gravity will be determined for three mixes: (a) 100% tailings, (b) 75% PAF and 25% tailings, and (c) 100%PAF. The required Chemical analysis and QXRD will be carried out in the city or at the Advanced Analytical Centre.

UCS and Slump Studies on Paste Fills

Indicative Funding
$65,900
Summary
The first part of the test is to determine the solid content of the nine different tailing slurries that would produce 260 mm slump. The next stage is to prepare the required number of specimens (93 in total) from the slurries mixed at the above solid contents. These 50 mm diameter and 100 mm length specimens will be tested after specific number of days for uniaxial strength. Complete stress-strain plots will be developed and UCS, Young's modulus and failure strain will be determined.
