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,并将其应用于矿井涌水量的分形预测。通过对井田涌水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,对矿井涌水量的增量趋势作了分形预测。
The concept of rescaled-range analysis of fractal theory is introduced in this paper.Discussion is made on the theoretical significance and the practical computation method of the Hurst exponent H and its ap-plication for the prediction of coal mine inflow growth.Based on the fractal calculation of mine inflow growth and according to the value of structure fractal dimension,a fractal prediction for the incremental tendency of gas emission in coal mine is conducted.
