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 ...

Mathematical modeling of tight roof periodical falling [PDF]
, 2018 The paper proposes a method to determine of a coal seam roof falling step basing upon the analysis of stress and strain state of the rock mass area with mine workings formed as a result of coal preparatory and extraction operations.

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).

Indications for different types of brittle failure due to active coal mining using waveform similarities of induced seismic events [PDF]
Solid Earth, 2013 Longwall mining activity in the Ruhr coal mining district leads to mining-induced seismicity. For detailed studies the seismicity of a single longwall panel beneath the town of Hamm-Herringen in the eastern Ruhr area was monitored between June 2006 and ...

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 ...

Review of an Improved Longwall Panel Layout for Ground Control in Longwall Mining
Shock and Vibration, 2022 Conventional longwall layout (CLL) for mining coal, trona, etc. is still fraught with problems including low resource recovery, wavy ground surface subsidence, bumps or rockbursts, gateroad support and maintenance, poisonous air hazard, spontaneous ...
