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 ...

Energy Science &Engineering, EarlyView.1. Against the backdrop of the dual carbon goals and the transformation of the energy structure, traditional coal and natural gas boilers struggle to meet the demand for economical and stable steam supply in small and medium‐sized enterprises. In response, this study proposes a solid‐state thermal storage steam production system, aiming to provide a ...

Pyrite oxidation in coal bearing strata:: controls on in-situ oxidation as a precursor of acid mine drainage formation [PDF]
, 2002 Pyrite oxidation in coal-bearing strata is recognised as the main precursor to Acidic Mine Drainage (AMD) generation. Predicting AMD quality and quantity for remediation, or proposed extraction, requires assessment of interactions between oxidising ...

Geopolitics and global strategy: Making money under anarchy
Global Strategy Journal, EarlyView.Abstract Research Summary Multinational firms conduct cross‐border trade and investment in a world of anarchy, where nation‐states must secure their survival in the absence of a world government. We develop a geopolitical‐economic order (GEO) framework to argue that the extent of geopolitical competition incentivizes states to create one of two types ...
