Optimization and Improvement of Dust Removal System of Continuous Shearer in Daliuta Coal Mine

open access: yes, 2020
In view of the fact that the existing continuous coal mining machine dust removal system can not solve the problem of dust overrun during the operation of the driving face of Shendong Daliuta Coal Mine, we point out the design defects of the existing ...

Life‐history traits and phylogeny structure taxon‐specific species–substrate relationships in deadwood

open access: yesOikos, EarlyView.
To understand the structuring of species assemblages, integrating life‐history traits and evolutionary heritage in analyses is vital. This allows the assessment of a mechanistic link between species and their environment. Deadwood systems are vital for nutrient cycling and biodiversity support, governed by complex intra‐ and inter‐specific fungal and ...

Impact of Waste‐Derived Slate Dust on Structural, Thermal, and Thermomechanical Behavior of Recycled Poly(Ethylene Terephthalate)

open access: yesPolymer Composites, EarlyView.
This study investigates the use of waste slate dust as a filler in recycled PET. Incorporating up to 20 wt% slate dust caused no filler‐induced molecular degradation, increased the crystallization temperature, thermal conductivity, and storage modulus. ABSTRACT Recycled polyethylene terephthalate (rPET) is widely considered a sustainable alternative to

Float coal dust explosion hazards [PDF]

open access: yes
"In underground coal mining, dust is produced at the face, at conveyors, at transfer points, and by the normal movement of workers and machines. The coarse coal dust particles settle rapidly.

Depositional and Hydrological Relationships Between Buried Dead Ice and the Active Layer in the McMurdo Dry Valleys, Antarctica: A Study of Sediment Geochemistry and Cation Concentrations

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The McMurdo Dry Valleys, the largest ice‐free region in Antarctica, are home to a cold‐desert hydrologic system of glaciers, snowbanks, streams, and lakes. Freshwater is also stored as dead glacial ice, which is poorly constrained in terms of ion concentrations and interactions with both in situ and overlying sediments.

Sustainable Utilization and Fire Protection of Wood‐Based Composites in Buildings: Innovations, Challenges, and Future Directions

open access: yesSustainable Development, EarlyView.
ABSTRACT The increasing use of wood and wood‐based composites in construction reflects a global shift toward renewable materials that support sustainable development objectives, including carbon reduction and responsible resource use. While wood offers substantial environmental benefits compared to conventional materials such as concrete and steel, its
