Application of a new brittleness index to estimate the proneness to brittle failure of rock around a deep tunnel [PDF]
, 2023 A major problem that may arise during the excavation of deep tunnels is the incidence of brittle failure of rock, induced by the stress release in a particularly heavy natural state of stress.

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**
Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 163-179, August 2025.Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.To address the substantial mining pressure from unstable rock formations, impact compression tests were performed on coal–rock combination specimens of varying strengths using a split Hopkinson pressure bar (SHPB). The dynamic mechanical properties, energy dissipation patterns, and failure modes of the specimens were systematically analyzed ...

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.The structural plane significantly changes the rock failure behavior. The connectivity of the structural plane generally varies for the rocks in different engineering practices or rock environments. In this manuscript, a series of direct shear tests on granite specimens are carried out using the true‐triaxial testing machine.
