Damage Characteristics and Stress Distribution Law of Overburden Rock in Multiple Mining of Close Coal Seams

Energy Science &Engineering, EarlyView.
This study on close coal seams shows that multi‐seam mining increases the height of the fractured zone from approximately 26 m (single upper‐seam mining) to about 49 m. When the lower seam is mined after the extraction of the upper seam, the heights of both the caved zone and the fractured zone increase by approximately two times.

Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds

Fire and Materials, EarlyView.
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product (FTP ...

“You just want to re‐open our biggest wounds, don't you?”: Homeplace ethnography as (polluted) environmental method

Feminist Anthropology, EarlyView.
Abstract When I was 12, my family told me a story about their community falling apart and coming together, a time when someone tried putting a nuclear facility in their (our?) hometown. Since we moved when I was too young to remember, the story had little significance until I embarked on a “hometown” ethnographic journey for my dissertation.
