Abstract：Water inrush in working face and support failure of the driven roadway caused by underground seepage occur from time to time. Based on experimental study on permeability behaviors of argillaceous rock during the complete stress-strain loading process，an analysis of the gradual development process of rock fissure under spatiotemporal changes in the roadway constructing area is carried out. Dynamic permeability evolving laws and three-directional(i.e. axial，radial，and circular) distributing characteristics of the surrounding rock have been explored. The laws are of great importance to determine key parameters of grouting depth，layout of grouting holes and optimum grouting opportunity. Further studies are presented to get perfect grouting opportunity and rational layout of grouting holes to prevent seepage disasters. A whole set of grouting control technology is put forward. A successful engineering case of a roadway crossing fault zone lying in sandstone bed aquifer is presented to provide valuable guidance for surrounding rock mass of roadway constructed under the threat of seepage. Thus，the slowing-down and even elimination of seepage disasters can be expected.
