Log‐Periodic Power Law Singularities in Landslide Dynamics: Statistical Evidence From 52 Crises
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Landslide movements typically show a series of progressively shorter quiescent phases, punctuated by sudden bursts during an acceleration crisis. We propose that such intermittent rupture phenomena can be described by a log‐periodic power law singularity model. Amounting mathematically to a generalization of the power law exponent from real to

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.

Energy Science &Engineering, Volume 13, Issue 8, Page 4252-4266, August 2025.ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding

A New Method to Assess the Possibility of Brittle Failure of Rock Induced by Deep Excavations
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 6, Page 1725-1746, 25 April 2025.ABSTRACT Spalling and rockburst are severe criticalities that can emerge while excavating deep tunnels in rock masses under heavy natural stress states. Here, rock brittle failure can induce massive releases of the energy stored during the excavation and dangerous projections of rock blocks into the opening.

Review on Rockburst Theory and Types of Rock Support in Rockburst Prone Mines
Open Journal of Safety Science and Technology, 2015 As the depth of mining increases, the occurrence of seismic events is becoming a more common phenomenon causing serious problems regarding to the stability and safety of mines. However, seismicity and the accompanying rockburst phenomena are not a well-defined and well-understood in underground excavations in these times. Efforts to clearly explain the

Deep Underground Science and Engineering, Volume 4, Issue 1, Page 3-17, March 2025.Hybrid rock fragmentation prediction models were developed by the combination of four machine learning methods and a Bayesian optimizer. Also, the prediction capabilities of the prediction models were evaluated based on R2, the root mean square error, and the mean absolute error.

Energy Science &Engineering, Volume 13, Issue 2, Page 752-764, February 2025.Dynamic impact failure test flow of bolted rock ABSTRACT Bolt support mechanisms represent a key technique to support the surrounding rock in coal mines. In deep rock engineering applications, the bolt‐supported structure of the surrounding rock of a deep roadway under high bearing stress may fail under dynamic loads such as those of blasting ...

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 ...
