FRACTAL CHARACTERISTICS OF FRACTURE DISTRIBUTION IN COAL

摘要: 运用分形理论对平顶山高庄矿戊8煤中断裂分布的分形特征进行了研究,结果表明,煤中断裂分布具有良好的统计自相似性,可以用分维描述。分维等值线图能有效地反映煤中断裂分布的复杂程度、分布范围和展布方向。分维是煤中断裂分布长度、条数和分布均匀程度等参数的综合指标,该指标随以上参数的变化而变化。

Abstract: The fractal characteristics of the fracture distribution in Coal seam No.V₈ in Gaozhung Coal Mine, Pingding-shan, are studied with the fractal theory. The results indicated that the fracture distributions are of well statistically self-simi-larity, described by using fractal dimension. The contour map of the fractal dimension can efficiently reflect the complexity, the range and the direction of fracture distributions. The fractal dimension is a comprehensive index of the length, number and homogeneity of the fracture distribution, which varies with the variations of above stated parameters.
