Research on prediction of residual deformation in goaf of steeply inclined extra-thick coal seam.
The residual deformation of a goaf is studied to improve the foundation stability assessment for metro lines passing through the subsidence area of steeply inclined extra-thick coal seams. The variable mining influence propagation angle is introduced to describe the special form of the rock movement...
