Study on the Energy Evolution and Stability of Roadway Surrounding Rock Under the “Simultaneous Mining–Driving” Condition

Energy Science &Engineering, EarlyView.
Based on theoretical analysis, the energy‐evolution behavior of the surrounding rock at various depths on the solid‐coal side of the 221303 material roadway during the “advancing‐toward‐mining” process was first clarified. Numerical simulations were then performed to validate and elaborate on the theoretical results.

Stress Redistribution Mechanisms and Subsidence Control of Fluidized Gangue Backfilling in Underground Coal Mining: Integrated Experimental and Numerical Investigation

Energy Science &Engineering, EarlyView.
Fluidized gangue backfilling controls mining subsidence through stress redistribution in composite backfill‐pillar systems, reducing surface settlement and stress concentrations. Multi‐scale experimental and numerical analysis provides quantitative design parameters for optimizing ground control in sustainable underground coal mining operations ...

Study on Damage Characteristics and Evolution Law of Macro‐Meso Structure of Surrounding Rock Under Mining Stress

Energy Science &Engineering, EarlyView.
Investigating the differential impact of mining stress on roadways, we find that in horizontally stressed environments, the inner surrounding rock exhibits more pronounced macro‐meso damage compared to the outer side. ABSTRACT The control of surrounding rocks in dynamic pressure roadways has consistently been one of the challenging predicaments in the ...

Study on Deformation Law of Crossing Layer Drilling Superimposed Floor Roadway

Energy Science &Engineering, EarlyView.
Based on deformation law of crossing layer drilling superimposed floor roadway, low dip angle drilling is particularly susceptible to complications such as borehole blockage and collapse. ABSTRACT Floor extraction roadway crossing layer drilling is a pivotal strategy for gas control in areas prone to coal and gas outbursts.

Cheia de axé (full of axé): Spirituality, resistance, and repair in Pernambuco's Afro‐Brazilian traditional communities

Feminist Anthropology, EarlyView.
Abstract This article explores how Afro‐Brazilian communities in Pernambuco respond to state‐led industrial development through culturally rooted practices of resistance and repair. Drawing on archival and ethnographic research in the coastal municipalities of Cabo de Santo Agostinho and Ipojuca, this study traces the effects of Brazil's large‐scale ...

Queer configurations: The female divine, regional identity, and Queer‐religious belonging in South India

Feminist Anthropology, EarlyView.
Abstract This article explores how queerness and religion intersect in a unique enactment of Bathukamma, a flower festival honoring the female divine in Hyderabad, the capital of the South Indian state of Telangana. Drawing on theories of figuration, I analyze how local queer organizations celebrate the festival in a way that engages two distinctive ...
