SHEAR-INDUCED PERMEABILITY EVOLUTION OF SANDSTONE FRACTURES

Shear-induced Permeability Evolution of Sandstone Fractures

In underground coal mines, shear-induced changes in regional fluid flow are a major factor causing water inrushes from faults into working faces.Shear slip along preexisting fractures tends to be activated during hydraulic fracturing, and this movement can either enhance or diminish hydraulic fracturing efficiency.To prevent water inrush disasters
