A Comprehensive Method for Subsidence Prediction on Two-Seam Longwall Mining

Energies, 2019
The purpose of mining subsidence prediction is to establish a reliable assessment for surface subsidence resulting from underground mining. In this study, a new method for predicting subsidence in two-seam mining is proposed.

Micromechanical computational modeling of reservoir compaction and surface subsidence

Matemática Contemporânea, 2000
The authors generalize computational dual porosity models developed for the case where the solid matrix undergoes elastic deformations. Variational formulation and the corrosponding two-level finite element approximations are proposed to discretize the dual porosity system.

Study on the Bearing Structure of Key Strata and the Linkage Evolution Mechanism of Surface Subsidence in Shallow Coal Seam Mining

Applied Sciences
Shallow coal seam mining results in the formation of various bearing structures in key strata, leading to varying degrees of surface subsidence and severe disruption to the surface ecological environment.

Dynamic prediction on goaf surface subsidence for the last two periods based on the Erf time function

Meitian dizhi yu kantan
BackgroundThe surface subsidence induced by coal seam mining represents a continuous dynamic evolution process. Constructing a full-time perdition model for surface subsidence in goafs holds significant theoretical and practical values for the rational ...

A Novel Approach for Predicting Mining Subsidence in Near-Horizontal Coal Seams by Coupling Key Stratum and Stochastic Medium Theories

Geofluids
With the increasing scale and intensity of coal mining, the subsidence range of the goaf continues to expand, seriously affecting the stability of surface buildings and restricting the ecological environment protection of mining areas.
