Constraints on the thermal and tectonic evolution of Greymouth coalfield [PDF]
, 1999 The southern end of the Paparoa Range in Westland, South Island, New Zealand, comprises an asymmetrical, southward plunging, faulted (Brunner-Mt Davy) anticline, the eastern limb of which is common with the western limb of an asymmetrical (Grey Valley ...

Deep Underground Science and Engineering, EarlyView.This study demonstrates the feasibility of an underground closed‐loop thermal storage facility at a post‐mining site, intended for seasonal heat energy storage. Its principal design shows water flow directions in winter and summer (1, 2), heat pumps (3), an upper water reservoir (4), and connecting pipes (5).

Tectonic discrimination diagrams revisited [PDF]
, 2006 The decision boundaries of most tectonic discrimination diagrams are drawn by eye. Discriminant analysis is a statistically more rigorous way to determine the tectonic affinity of oceanic basalts based on their bulk-rock chemistry.

Dynamic cracking properties and generating conditions of coal under rapid gas release
Deep Underground Science and Engineering, EarlyView.Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Experimental Study on the Mechanical Properties of Tectonic Coal Using Reconstituted Coal Specimens
, 2023 Tectonic coal, an aggregate of coal particles formed by compacting pulverized coal, has been developed extensively in China. Currently, reconstituted coal specimens are widely adopted to investigate the mechanical properties of tectonic coal, but they ...
