Abstract: Facing to the problem that the influence of expansion fracture fillings on fracture seepage is rarely studied at present, based on the test results of the hydrated properties of fracture fillings and the mechanical parameters of altered rock mass of Daye Iron Mine, the influence of the mechanical response of fillings on fracture seepage is discussed on the basis of the comparison of expansion stress of fracture fillings with mechanical parameter of altered rock mass. It is showed that the expansion effect of fracture fillings has an important influence on the deformational of altered rock mass. Both tensile effect and shear effect produced by fracture fillings can greatly increase the permeability of the fracture. What’s more, the plasticizing effect and liquefaction effect of fracture fillings can also improve the permeability of the fracture.

Key words: fracture fillings, mechanical responses, seepage, expansion effect
