Subsurface subsidence prediction model and its potential applications for longwall mining operations
Subsurface subsidence prediction model and its potential applications for longwall mining operations

摘要(Abstract):

This paper summarizes the development of an enhanced influence function method to predict longwall mining induced subsurface subsidence.This model takes the stratifications of the overburden,particularly the massive hard rock(i.e.,limestone and sandstone) layers,into consideration.A new deformation term,total strain or void intensity,has been introduced and can be determined from the predicted subsurface movements.This term reflects the volumetric expansion of overburden rock under the influence of mine subsidence.A case study has demonstrated the applicability of the enhanced subsurface subsidence prediction model.
