| 摘 要： | 在对综放工作面的煤样进行微观研究基础上,首次运用多重分形理论对顶煤裂隙的不均匀性和各向异性进行了定量表征,并将顶煤裂隙不均匀系数运用于渗透系数研究中,计算结果与实测基本吻合,表明运用多重分形方法,可为研究顶煤节理裂隙及其渗透性研究提供一个新的方法。

| Abstract: | Based on study of coal samples in mechanized longwall top-coal caving mining(MLTCM) face,anisotropy and inhomogeneity of top-coal fractures are quantitatively expressed,and inhomogeneity is applied in the study of permeability,the calculation results fits well with the observation results,which shows that multi-fractal method can provide a new method for the investigation of top-coal fracture and its permeability. |
