Occurrence and distribution of barite in the permo-triassic siksikpuk formation along the Brooks Range haul road [PDF]

, 1980
Barite commonly occurs in Permian to Triassic age rocks along the north flank of the Brooks Range. The Siksikpuk Formation (Wolfcampian to lowest Guadalupian age) is noted for its barite and is well exposed in the vicinity of Galbraith Lake along the ...

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

Microscopic time‐dependent mechanical behavior of shale derived from nanoindentation

Deep Underground Science and Engineering, EarlyView.
This study conducted grid nanoindentation creep tests to systematically analyze the microscopic creep behaviors of shale. Based on the analysis of creep strain rate sensitivity, the primary mechanism of microscopic creep in shale was found to be the extension and closure of microcracks.

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
