Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

Deep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Research on the intelligent capability maturity and evolution logic of open-pit coal mines

Gong-kuang zidonghua
Existing studies on the construction of intelligent open-pit coal mines have primarily focused on areas such as overall planning, basic architecture, and the evaluation of the completeness of construction content. However, there has been limited research

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Research on intelligent evaluation system of open-pit mine

Meikuang Anquan, 2022
In view of the lack of unified standards for the intelligent evaluation system of open-pit mines in our country, the lack of construction basis, evaluation criteria and other key issues in the construction process, research on the intelligent evaluation
