WebMay 30, 2024 · Key properties of the rock include velvety texture and appearance, conchoidal fracture, and fine grain. It may be very hard and tough. It is a contact metamorphic rock, formed when magma bakes its source material. Source Flett, John S. (1911). "Hornfels". In Chisholm, Hugh. Encyclopædia Britannica. 13 (11th ed.). WebIn deep rock engineering, evaluating the likelihood of rock burst is imperative to ensure safety. This study proposes a new metric, the post-peak dissipated energy index, which accounts for strain rate and size effects in assessment of the rock burst proneness of a rock mass. To investigate rock burst proneness, conventional compression tests were …
