During upward backfill mining of the close-distance coal seam group, the reasonable design of the backfill body compaction ratio (BBCR) of lower coal seam goaf plays a key role in controlling overburden strata movement and deformation. In this paper, the

Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

The rock-mixed ratio of top-coal caving mining significantly affects the coal quality and economic benefits. This ratio at longwall top-coal caving (LTCC) faces is jointly determined by multiple factors, including geological conditions, extracting and ...

Benthic contributions to the chemical seascape: Insights from Mediterranean underwater caves
Abstract Chemical mediation plays a major role in the functioning of marine ecosystems, yet most of the molecules sustaining species interactions remain largely unknown. As an initial step toward clarifying these processes, this study investigates how benthic biodiversity shapes the chemical composition of seawater, using underwater caves as model ...

Terrestrial Analogs to Titan for Geophysical Research
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Abstract River corridors are essential to life, but have been subjected to centuries of alteration, disconnection, and simplification. Process‐based river restoration has increased in recent years, with the goals of reversing degradation and reestablishing natural processes. Our objectives are twofold: (a) qualify the historic, ecologic, and geomorphic
