Deep Underground Science and Engineering, EarlyView.Stability analysis of compressed air energy storage caverns transformed from horseshoe‐shapes roadways in an abandoned coal mine is carried out. Both initial damage areas and two cavern shapes are numerically simulated using a one‐way coupling iteration algorithm of an improved generalization α method.

, 2013 We present a new algorithm to sample the constrained eigenvalues of the initial shear field associated with Gaussian statistics, called the `peak/dip excursion-set-based' algorithm, at positions which correspond to peaks or dips of the correlated density

Dynamics of Silent Universes [PDF]
, 1994 We investigate the local non--linear dynamics of irrotational dust with vanishing magnetic part of the Weyl tensor, $H_{ab}$. Once coded in the initial conditions, this dynamical restriction is respected by the relativistic evolution equations. Thus, the

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 ...

Energy Science &Engineering, EarlyView.ABSTRACT The degree of fragmentation of coal rock determines the porosity distribution of goaf porous media, which can be expressed using empirical formulas. However, this method fails in regions with nonuniform caving, dynamic disturbances, or deep high‐stress conditions. Therefore, this study developed a porosity optimization model comprising A and B

Evaluating shear test methods for stabilised rammed earth
, 2012 Rammed earth is an accessible, sustainable and increasingly popular building material. Owing to a lack of research, current design standards for rammed earth have taken a conservative stance on material attributes like shear strength.

A Novel True Triaxial Apparatus for Testing Shear Seepage in Gas-Solid Coupling Coal
Geofluids, 2018 To study the effects of shear stress on the mechanical and seepage properties of gas-bearing coal in three-dimensional stress conditions, a novel true triaxial apparatus (TTA) was developed for the rigid loading of the major principal stress σ1 and the ...
