单裂隙粗砂岩渗流规律试验研究

摘要

以石嘴山矿西翼采区为研究背景,通过三轴应力作用下岩石单裂隙渗流试验、裂隙开度与有效压力关系试验和大尺度岩石表面粗糙度量测试验,结合渗流力学基本理论,揭示了三维应力下单裂隙粗砂岩渗流规律,建立了有效压力、裂隙开度与渗透系数的关系式,以期丰富裂隙岩体渗流的理论研究.%Based on geologic background of Shi Zuishan colliery, the single rock fracture seepage tests under the triaxial stressdo exists, the relations tests between the effective confining pressure and the fracture aperture. This paper revealed the single fracture gritstone seepage law in the three dimensional stress,and established the relationship among effective confining pressure, fracture pressure and coefficient of permeability, in order to enrich the seepage theory research on fractured rock mass.
