Unveiling spatial heterogeneity in urban underground space development patterns and mechanisms for differentiated planning: A points of interest‐based study of Shanghai

open access: yesDeep Underground Science and Engineering, EarlyView.
This study investigated the spatial patterns and development mechanisms of urban underground space (UUS) in Shanghai using underground points of interest data. It revealed distinct development mechanisms between the main city and suburbs, highlighting the need for differentiated UUS planning and policies to optimize underground space resources ...

Geodiversity is an inseparable but underutilized aspect of ecological connectivity assessments under climate change

open access: yesEcography, EarlyView.
Conservation has shifted towards a climate change adaptation approach in which expected species range shifts are increasingly considered to mitigate effects of climate change and habitat fragmentation on biodiversity. As part of this, ecological connectivity needs to be ensured to support gene flow and viable populations in the face of changing ...

A bedform phase diagram for dense granular currents Senior Lecturer in Geology Head of Geology, Lecturer Post doc researcher

open access: yes
Pyroclastic density currents are a life-threatening volcanic hazard. Our understanding and hazard assessments of these flows primarily rely on interpretations of their deposits. The occurrence of stratified layers, cross-stratification, and dune bedforms in these deposits has been assumed as indicative of dilute, turbulent, flows causing traction ...

Experimental and Theoretical Investigation on the Progressive Breaking Law of Thick and Hard Rock Strata in Deep Mining

open access: yesEnergy Science &Engineering, EarlyView.
This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...
