Research of the Backfill Body Compaction Ratio Based on Upward Backfill Safety Mining of the Close-Distance Coal Seam Group

open access: yes, 2022
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 for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

open access: yesEnergy Science &Engineering, Volume 14, Issue 6, Page 2941-2960, June 2026.
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.

Study of evaluation of economic rock-mixed ratio of longwall top-coal caving working face based on entropy weight-extension theory

open access: yesMeitan kexue jishu
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 ...

Field Study on the Law of Surface Subsidence in the High-Intensity Fully Mechanized Caving Mining Working Face with Shallow Thick Bedrock and Thin Epipedon in Hilly Areas

open access: yes, 2021
Shallow and thick coal seams occur extensively in hilly areas in Shanxi Province and Shaanxi Province, China. The surface damage and landslides caused by shallow fully mechanized caving mining have a very serious impact on the environment.

Benthic contributions to the chemical seascape: Insights from Mediterranean underwater caves

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
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

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
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 ...

Determination of parameters of the underground inclined coal seam mining in Quang Ninh basin under protected objects on the surface

open access: yes, 2017
Based on analysis of mining and geological conditions of natural occurrence of coal seams at Quang Ninh basin it has been determined that more than 37 % of deposit reserves are located under the protected surface objects. To justify the possible variants

Monitoring Change in Floodplain Vegetation Due To River Restoration Treatments With Remote Sensing in the Intermountain West

open access: yesWater Resources Research, Volume 62, Issue 6, June 2026.
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
