Application of intelligent top-coal caving technology in overlying aquifer protection of extra-thick coal seam

Meitan kexue jishu
The grassland areas in eastern Inner Mongolia and northern Xinjiang are rich in coal and groundwater resources. The mining fissures formed by high-intensity coal mining are easy to lead to the strong water-rich aquifer, and it is very easy to cause the ...

Prediction of the height of caving zone above the undercut in block caving mining method

Rock Mechanics Letters
The block caving is one of the most commonly used methods in underground mining of massive, low/high grades, and deep deposits. As a result of undercutting, caving occurs and propagates toward the upper part of the ore block. It is essential to predict the height of caved ore and its volume based on shape of the caved zone to make an economic decision.

Expanding the Faunal Interpretation of the Cova Eirós (NW Iberia) Middle Paleolithic–Early Upper Paleolithic Record With ZooMS

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The Cova Eirós archaeopaleontological site preserves the most comprehensive archaeostratigraphic sequence in the northwestern Iberian Peninsula, with an exceptionally rich record spanning from the Mousterian to the Upper Paleolithic. The extensive fragmentation of the faunal record and the rich taxonomic diversity at this site have limited the

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.

Catchment conversion to agriculture alters freshwater macroinvertebrate community responses to flow disturbance: results from a replicated in‐stream experiment

Oikos, EarlyView.
Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

Detecting social‐ecological fit in Natura 2000 governance and management: Evidence from LIFE projects focused on forest protected habitat types

People and Nature, EarlyView.
Abstract Protected areas represent complex social‐ecological systems that require governance and management approaches that valorise and enhance positive relationships between people and nature. This study analyses the alignment between social and ecological systems to detect the social‐ecological fit of projects focused on biodiversity conservation ...

A dramaturgy of uncertainty: Transdisciplinary manoeuvres across forestry and theatre

People and Nature, EarlyView.
Abstract The uncertainties of climate change mean that forestry adaptation strategies are often complex and contested. Research has suggested that there is an interest in the forestry sector for facilitated dialogue about uncertainty (de Pellegrin Llorente et al., 2023).

Epistemic diversity and the politics of knowledge in plant disease management: Insights from the Xylella fastidiosa epidemic in southern Italy

PLANTS, PEOPLE, PLANET, EarlyView.
Xylella fastidiosa is a major plant pathogen affecting crops such as grapes, citrus, almonds, and olives, with potentially severe consequences for agricultural production and rural livelihoods worldwide. This paper examines the conflict around the management of the X. fastidiosa outbreak affecting olive trees in southern Italy.
