Construction of Domain Knowledge Graph Base for Coal Mine Rock‐Burst Prediction and Prevention Based on Ontology

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT In China, as the mining depth of coal mines increases, the occurrence conditions of coal seams are becoming increasingly complex, leading to a continuous rise in the risk of rock‐burst. The frequent occurrence of such accidents has caused severe losses to the safe production of coal mines.

A Rapid Method for the Determination of Coal Seam Gas Pressure Based on Raw Coal Adsorption

open access: yesEnergy Science &Engineering, EarlyView.
The method flow of coal seam gas pressure measurement based on raw coal gas adsorption is introduced. ABSTRACT The residual gas pressure of pre‐pumped coal seams is one of the key indices to check the effect of regional outburst prevention. The success rate in direct measurement is low, and it is generally obtained indirectly by use of the Langmuir ...

Investigation Into the Evolutionary Characteristics of Damage in Rock Strata at the Base of Soft, High‐Gas Coal Seams Under High In Situ Stress During Permeability‐Enhancing Blasting

open access: yesEnergy Science &Engineering, EarlyView.
This study established a bidirectional loading gas‐solid coupling blasting simulation system capable of multidimensional characterization in the laboratory, revealing the core mechanism by which in situ stress significantly inhibits the expansion of explosion cracks in deep soft coal floor blasting for enhanced permeability. The research indicates that

Feelings of female solidarity: An ethnographic account of trans‐exclusionary feminism

open access: yesFeminist Anthropology, EarlyView.
Abstract In this article, I argue for an ethnographic engagement with trans‐exclusionary feminism. Using my fieldwork in a gender‐critical collective in the United Kingdom as an example, I show how feminist anthropology can give insights into the motivations and emotional trajectories of gender‐critical feminists.
