摘要
以深部软岩中黏土矿物为研究对象,运用Image-proplus专业图像分析软件,对黏土矿物微观结构SEM图像进行处理,提取孔隙信息,结合分形理论,对微观孔隙结构进行分形数值分析。研究表明：软岩中黏土矿物微观孔隙结构分布具有分形特征,试样的分形维数在1~2。具有不同微观结构形态的相同类型黏土矿物和具有同种微观结构形态的不同类型黏土矿物,其分形维数均有差异。孔隙分布均匀程度与分形维数成反比。
This paper is mainly devoted to study on clay mineral of soft rock in deep mine. Based on the fraetal theory, the paper presents a numerical analyisis on the fractal characteristics of micro pore structure for clay mineral with the help of SEM technique and image-pro plus professional software. The results show that the micro pore distribution of soft rock clay mineral has the fractal characteristics and the fractal dimension is 1 to 2, and there is difference between the same clay mineral with different micro pore structure and different clay mineral with same micro pore structure. Homogeneous degree of micro pore distribution is inversely proportional to the fractal dimension.
