Failure Mechanism of Asymmetric Large Deformations Under Repeated Mining in Roadways

Energy Science &Engineering, Volume 14, Issue 3, Page 1195-1212, March 2026.
Principal stress‐evolution diagram at different advance positions of 42205 working face. ABSTRACT To address the challenge of controlling severe asymmetrical deformation in roadways subjected to repeated mining, this study (i.e., based on the engineering context of the Buertai Coal Mine) investigated the characteristics of the regional stress field in ...

Quantifying the Hydrological Niche of Upland Swamp Plant Communities Using Indicator Species

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Coastal Upland Swamps of the Sydney Basin Bioregion, Australia, are highly biodiverse upland mires. Swamp vegetation organises into five communities, thought to occupy distinct positions along a hydrological gradient. Longwall mining reduces the duration of root zone saturation, but lack of quantitative understanding of hydrological niche ...

Hardening and Hollowing Out Private Property: Rentiership, Dispossession, and Planetary Extraction in the Marcellus Shale

Antipode, Volume 58, Issue 1, January 2026.
Abstract Southwestern Pennsylvania (SWPA) has long been an energy extractive periphery, continuously remade through cycles of dispossession and accumulation. Here we examine the changing dynamics of private property in these cycles and its central role in the latest phase of extraction—unconventional oil and gas development (UOGD).

Method for Characterizing the Development State and Spatiotemporal Evolution of Mining‐Induced Overburden Fractures

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Mining‐induced coal seam extraction causes deformation and fracturing of the overburden, leading to the development of fractures, which pose significant threats to mine safety, surface structures, and natural ecosystems. To address the challenge of quantitatively characterizing overburden fractures caused by coal seam mining, this study, taking the 12 ...

Distribution Characteristics of Stress Sources and Surrounding Rock Structure Control Techniques of Gob‐Side Entry Driving in Extra‐Thick Coal Seam

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
To address the challenges of surrounding rock control caused by complex stress sources and intense ground pressure in gob‐side entry driving (GED) with narrow coal pillars under extra‐thick coal seams, this study takes the 10 m‐thick coal seam 8204 panel of Tashan Coal Mine as the engineering background.

Synergistic Bearing Effect and Failure Mechanism of Backfill–Coal Pillar Composite Structure

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Constructing backfill walls adjacent to the yield coal pillar can effectively enhance its stability. The backfill and coal pillar form a synergistic bearing structure that jointly maintains the stability of the overlying strata. To reveal the synergistic bearing effect and failure mechanism of the backfill–coal pillar structure, this study first ...

Off-Site Geological Surveying of Longwall Face Based on the Fusion of Multi-Source Monitoring Data

Mathematics
A high-precision coal seam model is crucial to improving the adaptability of unmanned mining technology to geological conditions. However, the accuracy of a coal seam model constructed with boreholes and geophysical data is far from the required accuracy

Hydraulic support crushed mechanism for the shallow seam mining face under the roadway pillars of room mining goaf

International Journal of Mining Science and Technology, 2017
While the fully-mechanized longwall mining technology was employed in a shallow seam under a room mining goaf and overlained by thin bedrock and thick loose sands, the roadway pillars in the abandoned room mining goaf were in a stress-concentrated state,

Variability and Trends in Selected Seismological Parameters During Longwall Mining of a Coal Seam Disrupted by a Rockburst

Applied Sciences
Seismic tremors provide valuable insights into stress redistribution and accumulation, often serving as indicators of these processes within the rock mass, which can precede or accompany rockburst occurrences.
