Deep Underground Science and Engineering, EarlyView.This study highlights that with the static and time‐dependent evolution of slip versus dilation tendency parameter space, structurally controlled deep geothermal systems can be selected within areas of higher permeability and lower seismic hazard. Abstract Faults play a vital role in the Earth's hydraulic system by facilitating fluid flow when dilating

Adsorption Dynamics Characteristic of Tectonic Coal in Yuwu Coal Mine
Meikuang Anquan, 2020 Aiming at the methane adsorption dynamics characteristics of tectonic coals, Yuwu Coal Mine of Lu’an Group in Shanxi Province was chosen as the engineering background. Four tectonic coal samples with different degrees of destruction were selected for high-pressure mercury intrusion porosimetry and methane isothermal adsorption experiments, and the pore

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 ...

Influence of man-made edaphotopes of the spoil heap on biota [PDF]
, 2018 The aim of the work is to investigate the influence of man- made edaphotopes of colliery spoil heap on biota by bioindication method. The physicochemical properties of edaphotopes were investigated: humidity, substrate temperature,

Critical expansion points: Mechanical signs of surrounding rock instability
Deep Underground Science and Engineering, EarlyView.This study proposes the Rock Bearing‐Expansion Model (RockBEM) with critical expansion points (CEPs) to quantify post‐peak damage stages in deep‐buried rock masses via plane strain compression test (PSCT). CEP hysteresis&interval ratios reveal bearing performance dynamics and failure severity, advancing mechanistic insights into deep underground rock ...
