A Water-Rock Coupled Model for Fault Water Inrush: A Case Study in Xiaochang Coal Mine, China

Advances in Civil Engineering, 2019
Water inrush disasters in mining frequently occur under the influence of confined water-bearing fault zones. Therefore, investigating the fault water inrush mechanism is necessary to reduce the number of occurrences of this type of disaster.

Real‐time prediction of tunnel boring machine thrust based on multi‐resolution analysis and online learning

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 28, Page 5212-5227, 28 November 2025.
Abstract This study introduces a novel integrated framework for real‐time tunnel boring machine (TBM) thrust prediction, addressing critical limitations in handling non‐stationarity, complex spatiotemporal dependencies, and abrupt disturbances. First, a real‐time windowed multi‐resolution analysis process, which performs decomposition strictly within ...

Analysis of squeezing‐induced failure in a water tunnel and measure of rehabilitation: A case study of Tishreen tunnel, Syria

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 498-510, September 2025.
Different failure modes observed in Tishreen tunnel include Floor heave, wall spalling, crashing of slab, and lining convergence reaching the failure limit. Abstract Squeezing phenomena can lead to severe loads in deep tunnels, especially in the presence of a low ratio of surrounding rock strength to overburden pressure.

Identification and Prediction Method of Working Face Water Inrush of Isolated Overburden Grout Injection

Energy Science &Engineering, Volume 13, Issue 8, Page 4046-4058, August 2025.
ABSTRACT Isolated overburden grout injection (IOGI) is an economical and efficient green mining technology. During the grout injection process, a large amount of slurry bled water will enter the underlying rock strata below the grouting layer. Under certain conditions, the slurry bled water may seep along the overlying rock layer into the water ...

Evaluation of Water-Inrush Risk and Water-Preserved Mining Under Goaf Water

Water
In coal seam mining operations, the presence of overlying water bodies presents persistent challenges, particularly during multi-seam extraction, where water accumulation in upper seam goafs requires careful management. This study examined the Lingzhida Coal Mine, focusing on the geological conditions of the 3# seam (upper) and the 15# seam (lower), as
