A Novel Surface Subsidence Prediction Model Based on Stochastic Medium Theory for Inclined Coal Seam Mining

Advances in Civil Engineering, 2023
Most coal resources are deposited in the form of inclined coal seams, and surface subsidence basin morphology induced by the mining of inclined coal seams is frequently skewed. The probability integral method with symmetrical distribution characteristics

Subsidence Prediction of Overburden Strata and Surface Based on the Voussoir Beam Structure Theory

Advances in Civil Engineering, 2018
The hard and stiff strata (key strata) bear the overburden load in the form of a voussoir beam structure (VBS) after break. The VBS affects both the surface subsidence and the stope underground pressure.

Analysis on Subsidence Law of Bedrock and Ultrathick Loose Layer Caused by Coal Mining

Geofluids, 2021
In the process of coal mining, when the buried depth is large and the loose layer is thick, the ground subsidence tends to be abnormal, thus causing great damage to the surface ecological environment.
