Abstract:The mechanical properties of rock materials significantly depend on their size due to their heterogeneity and the spatial randomness of joint development—a factor often neglected in pillar design and stability analyses within mining engineering. The rock samples examined herein were 100 mm in diameter and 100 mm, 200 mm, or 300 mm in height. This research analyzed the respective mechanical phenomena and failure patterns of rock specimens with varying height-to-diameter ratios under uniaxial compression. The ex… Show more
