Rock mechanics test is not only the basis for obtaining the mechanical parameters of rock but also an important means for studying rock mechanics and engineering. In this paper, the uniaxial compression deformation test, Brazilian splitting test, and cornea pressure shear test are carried out for rocks in the Dajishan tungsten mine. The basic mechanical parameters such as …

Specimen Preparation. Rock specimen preparation is paramount regardless of what material you are testing or the level of sophistication of your rock testing system. A poor quality specimen can only produce misleading results, wasting valuable time and resources. As such, precise and accurate uniaxial or triaxial testing can only be achieved ...

The coal-rock samples were collected from the lower end of 402102 working face in Hujiahe mine, Shanxi. According to the standard of International Society for Rock Mechanics, the core drilling rig was first used to drill a cylindrical sample with a diameter of 50 mm [24, 25]. Then, the stone sawing machine was used to cut the sample to the ...

Loading rate is an important impactor of the mechanical properties, as well as the deformation and failure mode of coal and rock. Using an RMT-301 rock mechanics tester and a Soft Island acoustic emitter, uniaxial compression and acoustic emission (AE) tests were carried out on coal samples under different loading rates.

Rock burst occurs frequently as coal mining depth goes deeper, which seriously impacts the safety production of underground coal mines. Coal seam water injection is a technique commonly used to prevent and control such accidents. Moisture content is a critical factor tightly related to rock burst; however, an in-depth insight is required to discover their …

Glauconite pellets were separated from the whole rock by heating the lightly crushed samples with Na 2 CO 3 solution, followed by sieving (500 ASTM). Glauconite pellets were handpicked using a Zeiss Stemi 2000 stereo-zoom microscope for XRD analysis. The pellets were smear-mounted on a glass slide for oriented sample preparation.

The Hoek–Brown criterion was introduced in 1980 to provide input for the design of underground excavations in rock. The criterion now incorporates both intact rock and discontinuities, such as joints, characterized by the geological strength index (GSI), into a system designed to estimate the mechanical behaviour of typical rock masses encountered in …
