Orthogonal array analysis of overburden failure due to mining of multiple coal seams [PDF]
Journal of the Southern African Institute of Mining and Metallurgy, 2019 This paper presents a numerical analysis that uses an orthogonal array to investigate overburden failure caused by longwall mining of multiple coal seams. An LN(s k) array is said to be an orthogonal array with s levels, N rows, and k columns. This analysis identifies the contrasting factors that influence the height of the caving and water-conducting ...

Yantu gongcheng xuebao, 2018 Many high embankment dams are directly located on the deep overburden layer. After the dam is constructed, large stress and shear displacement will appear in the dam foundation, which has great influence on the seepage stability of the overburden layer ...

Numerical Simulation on Failure Rules of Overburden Strata in Shallow Coal Seam
IOP Conference Series: Earth and Environmental Science, 2021 Abstract The mining, under the condition of the shallow coal seam, the thick loose beds and the thin base rock in Shendong mining area in Shaanxi province of China, makes the surface subsidence take on the situation of the discontinuous falling crack failure.

Law of overburden failure and roof water damage in Yuandatan Coal Mine
Meikuang Anquan, 2022 The Jurassic coal field in northern Shaanxi Province is generally threatened by roof water damage, so it is vital to study the law of overburden failure for mine safety production. Taking Yuandatan Coal Mine as an example, the development height of “two zones” in overlying rock of 11201 first working face of 2# coal seam was analyzed and studied ...

Effects of Overburden on Deformation and Failure of Anti-Dip Slopes under the Action of Seismic Load
, 2011 A large number of mountain disasters were induced by Wenchuan Earthquake, and as one type of them, the deformation and failure modes of anti-dip slopes were influenced by overburden.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome
FEBS Letters, EarlyView.This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
