A small-scale quadratic rock segment of 30 × 30 mm 2 (with 1500 spheres) was subjected to biaxial compression (Fig. 6). The pre-existing macro-pores were neglected. The micro-pores corresponded to the free space between spheres (the initial specimen's porosity was 5%). The diameter of spheres lay in the range of 0.7–1.3 mm …

Small-Scale Processing of Hard Rock Ores. December 2014 by Chris Ralph. Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that …

Deformation measurement is crucial for understanding the mechanical responses of rock masses; however, full-scale tests on rock masses are difficult and costly. With the development of 3D technology, small-scale tests provide a promising solution. Nevertheless, traditional DIC codes usually fail due to the existence …

Similar phenomena have been reported and discussed in other studies in terms of small-scale rock blasting (Dehghan Banadaki, 2010; Jayasinghe et al., 2019; Gharehdash et al., 2020). At a distance of approximately 30 mm from the top surface, a fracture surface can be seen. As the stress wave propagated parallel to the axis of the …

Small-scale shear tests on rock specimens were performed in this work to investigate the rock bridge breakage stage, while large-scale physical simulation tests were conducted to investigate the block instability stage. Due to the cost and other constraints, large-scale simulation testing of rock bridge breakages takes time to execute. ...

5.4 Small-Scale Deformation. The microscale behaviour has been analysed in term of global stress-strain response of elementary areas. However, deformations at microscale occur within the EAs due to solicitations. To enlighten them, an analysis of the small-scale deformation is presented during a biaxial loading ((sigma _3 = 12, hbox …

ABSTRACT. This paper describes a small laboratory test on flexural toppling failure of rock slope. This failure process involves slip between columns and tensile rupture across the colums. Gypsum columns with non-persistent cross joint were used to make a physical modeling for the slope failure mechanism.The slope model composed of the …

To investigate the influence of a small-scale single structural plane with hard fillings in the surrounding rock of deep tunnels on the rockburst process, a series of biaxial compression tests were conducted on granite specimens (200 mm × 200 mm × 30 mm) with a circular hole of 50 mm in diameter. The characteristics of the rockburst …

These observations are not consistent with 1-D thermal diffusion models, which predict complete age resetting of low-temperature thermochronometers >50m from the contact (Karlstrom et al., 2019, Biasi and Karlstrom, 2021, Shuster et al., 2023).Thus, this location is an ideal setting for exploring hydrothermal circulation and water–rock …

understanding rock properties and providing reliable guid-ance for engineering support. A small-scale test, with the advantages of low cost, easy operation, high precision, etc., is signicantly better than a large-scale test. Nevertheless, ideal small-scale specimens are dicult to prepare, and nat-
