Mechanism and Predicting Theory-Based of Rockburst Evolution [PDF]

, 2017
Mechanism and predicting of rockburst is complicated, and there is no mechanism and prediction model to explain the occurrence of rockburst satisfactorily. In this chapter, the mechanism of rockburst stress-energy evolution is obtained by analyzing the pre-peak stage of rock compressive deformation.

A review on rockburst prediction and prevention to shape an ontology‐based framework for better decision‐making for underground excavations

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 331-349, June 2026.
A scientometric analysis of 2449 journal articles and a comprehensive review of 336 papers were conducted, discussing and identifying challenges and research gaps in rockburst prediction and prevention and proposing an ontology‐based framework for better decision‐making in underground excavations. Abstract With underground engineering projects becoming

Rockburst prediction based on multi-featured drilling parameters and extreme tree algorithm for full-section excavated tunnel faces

Journal of Rock Mechanics and Geotechnical Engineering
The suddenness, uncertainty, and randomness of rockbursts directly affect the safety of tunnel construction. The prediction of rockbursts is a fundamental aspect of mitigating or even eliminating rockburst hazards.

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

Energy Science &Engineering, Volume 14, Issue 6, Page 2941-2960, June 2026.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Study on the Energy Evolution and Stability of Roadway Surrounding Rock Under the “Simultaneous Mining–Driving” Condition

Energy Science &Engineering, Volume 14, Issue 4, Page 2225-2247, April 2026.
Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.

Landslide Activity in the European Alps ‐ Part 1: A Machine Learning Based Instrumental Catalog From the Analysis of Seismological Data

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Landslides in the European Alps are a growing concern in the context of climate change. However, landslide catalogs for the European Alps remain incomplete, often lacking precise timing and containing few, if any, entries for remote areas.

Stress analysis of crack characteristic of anthracite under dynamic loading

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 56-65, March 2026.
In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under

Analysis of Underground Cavern Surrounding Rock Stability and Anchoring Effects Under High Stress Using an Optimized DDARF Method

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study focuses on the stability of surrounding rock (SR) in underground cavities of China’s western high‐stress regions, using the tailwater pressure–regulating chamber of a hydropower station on the lower Jinsha River as the case. Models with and without bolts are established for excavation simulation.
