Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage

Deep Underground Science and Engineering, EarlyView.
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the cavern.

Early warning for landslide of rock slopes in open-pit mine based on rockfall video monitoring

Yantu gongcheng xuebao
The stability of rock slopes is one of the most critical issues for the safe production in an open-pit mine. Providing early warning signals and issuing accurate evacuation orders for the rock landslides is of practical engineering significance.

Image processing for erosion control of open-pit mines

, 2016
Soil erosion is one of the most severe land degradation problems afflicting many parts of the world where topography of the land is relatively steep. Owing to inaccessibility to this steep terrain, such as slopes in open-pit mines and forested mountains,

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.
