Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework

Energy Science &Engineering, EarlyView.
ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...

Research on the Mechanism of Sand Bridge Stuck Drill in Deep Coal and Rock Gas Horizontal Wells

Energy Science &Engineering, EarlyView.
Accounting for wellbore collapse debris and the bulldozer effect, this study develops models for permeable and impermeable sand bridge sticking in deep CBM horizontal wells, deriving resistance and volume formulations. Validated in Changqing, results show impermeable bridges dominate; controls (fluid optimization, staged drilling, circulation, speed ...

Analysis of the Algorithm Monitoring the Geometric Parameters of the Powered Support Based on Station Tests

Energy Science &Engineering, EarlyView.
ABSTRACT The powered roof supports in the longwall complex are placed and interconnected next to one another, typically about 125–250 units in a longwall face. It is an essential component in the longwall complex, which also includes a shearer (or plow) and an armored face conveyor.

Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters

Energy Science &Engineering, EarlyView.
Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.
