Study on the effect of mining height on overburden strata movement in longwall mining

International Journal of Coal Science & Technology
The mining height of a coal seam is a critical factor influencing the detachment, collapse, and formation of the collapse angle of the strata during strata movement. To clarify the mechanism by which mining height affects strata movement characteristics,

Experimental and constitutive modeling investigations on marble in Jinping Underground Laboratory

Deep Underground Science and Engineering, EarlyView.
The objective of this study is to reveal the underlying mechanisms behind the brittle‐ductile transition of the marble through a combination of experimental research and constitutive modeling. A series of triaxial compression and triaxial cyclic loading tests are conducted.

Study and application of dynamic response characteristics of support in full-mechanized top coal caving with large mining height

Meitan xuebao
The dynamic response characteristics of stope support include the information of support resistance increase and live column shrinkage, which is not only an important index to reflect the strength of mining pressure behavior in working face, but also the

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, EarlyView.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.
