Energy Science &Engineering, EarlyView.This study primarily investigates the optimal width for coal pillar retention in both sides of the worked‐out face section. Taking the 42201 haulage roadway of the 42201 working face at Shengxin Coal Mine as the primary research target, it analyses the optimum width for coal pillar retention through theoretical calculations, numerical simulations, and ...

Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Multifactorial Screening for Fine‐Scale Selection of CCS Industrial Clusters and Hubs in Brazil
Greenhouse Gases: Science and Technology, EarlyView.ABSTRACT As Brazil moves toward implementing its decarbonization commitments, carbon capture and storage (CCS) hubs are emerging as a key pathway for large‐scale CO2 abatement in hard‐to‐abate sectors. This paper presents a multifactorial, data‐driven framework to screen and prioritize potential CCS industrial clusters and hubs across Brazilian regions,

The relationship between cellular protein content and selenium accumulation in freshwater microalgae
Integrated Environmental Assessment and Management, EarlyView.Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Subsidences Due to Underground Mining
Geografie, 1986 The origin and evolution of sinkholes as well as of large subsidence depressions above underground excavations are explained by the changes in strain in rocks due to the mining activity. But on the periphery of the destructive ellipsoid the extension of rocks and the upheaval of the earth surface also take place, caused by the lowering of the strain ...
