Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

Energy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Understanding Sex‐Specific Behavioral States of Bobcats in Response to Highway Proximity in South Texas

Ecology and Evolution, Volume 16, Issue 8, August 2026.
ABSTRACT Roads are a major source of landscape fragmentation that can influence movement patterns, survival, and behavioral states of carnivore species. Understanding their behavior and response to roads is crucial for developing effective mitigation strategies such as wildlife crossing structures, exclusion fencing, and habitat connectivity planning ...

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, Volume 14, Issue 8, Page 3697-3725, August 2026.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Modified vehicle lighting reduces wildlife collision risk by enhancing deer and wild pig avoidance responses at night

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Generally, LED headlights had neutral or beneficial effects on wildlife responses, suggesting they could reduce collisions given the increased illumination levels they provide drivers. Additionally, our results support previous research indicating increased frontal vehicle illumination can reduce dangerous encounters with wildlife. Our findings suggest

The role of mining-induced seismicity amplitude and frequency in gob-side roadway rib spalling

Energy Exploration & Exploitation
During underground coal mining, Mining-induced seismicity is a crucial factor leading to roadway deformation. Based on a case study of rib spalling caused by mining-induced seismicity in China, this paper utilizes the Universal Distinct Element Code to investigate the mechanism of rib spalling.

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study

Engineering Reports, Volume 8, Issue 4, April 2026.
The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.
