Failure mechanism of the coal wall at the working face based on an eccentric compression mechanical model

Deep Underground Science and Engineering, EarlyView.
In this study, the nonuniform distribution of the bearing pressure in front of the coal wall has been revealed based on in situ monitoring data and numerical simulation results. Therefore, an eccentric compression mechanical model of the coal wall was established to study the deformation and failure characteristics of a coal wall. The slenderness ratio

Experimental study on dynamic behavior analysis of coal and its acoustic emission response characteristics under impact failure

Deep Underground Science and Engineering, EarlyView.
Based on acoustic emission response characteristics, it can be more accurate to identify the damage evolution process of coal under the combined dynamic and static loads, reveal the moment corresponding to coal damage, and identify the characteristics of coal failure. The research results are conducive to the further use of acoustic emission monitoring

Form and load transfer aspects of foundation systems: Case‐based implementation and adaptation for buildings

Deep Underground Science and Engineering, EarlyView.
Upon conceptualization of structural behavior, foundations in terms of their form are divided into linear (1D), planar (2D), and volumetric (3D). Regarding the load transfer mechanisms, linear foundation systems are considered vector‐acting, planar foundations are divided into section and surface‐acting, and volumetric ones are recognized as block ...

Stress analysis of crack characteristic of anthracite under dynamic loading

Deep Underground Science and Engineering, EarlyView.
In this article, the dynamic compression test of anthracite under five strain rates is carried out, the evolution law of three kinds of crack characteristic stress is analyzed, and a prediction model of the crack characteristic stress threshold considering the strain rate effect is established. Then, the rationality of crack characteristic stress under
