Abstract

A dual-porosity poroelastic model is presented with the emphasis on identifying the effect of interaction between fractures and porous matrix on the change in fluid pressure and solid deformation as a result of mining. In comparison to a single-porosity poroelastic model the analysis reveals that the dual-porosity model generates larger deformation and produces a substantially different fluid pressure profile in the initial period. The poroelastic behaviour of the porous media is apparently affected by fluid exchange between the fracture phase and the porous matrix phase, resulting in a history of delayed pressure dissipation. -from Authors
