摘要: 介绍了分形理论中的时间序列 (R/S)分析方法, 讨论了赫斯特指数的理论意义和实际计算方法, 并将其应用于矿井瓦斯涌出量预测。通过对矿井瓦斯涌出量时间序列的分形处理, 根据极差、标准差的结构分维值的大小, 对矿井瓦斯涌出量的增量趋势做了分形预测。

Abstract: The concept of rescaled-range (R/S) analysis of fractal theory is inrtoduced in this paper.It is discussed,that the theoretical significance and the practical computing method of the Hurst exponent H,and use H for the prediction of gas emission in coal mine.Base on the fractal calculation of gas emission in coal mine and according to the value of structure fractal dimension,a fractal prediction for the incremental tendency of gas emission in coal mine is conducted.
