矿井涌水量的R/S方法分析
|
摘要
R/S分析方法是以时序数据为基础的一种非线性理论方法,可以应用于对时间序列数据进行分析与预报。文章通过正确估算赫斯特指数、分维数,分析其变化规律,对涌出时间序列进行了分析,初步探讨了涌水量的变化规律。实例研究表明,该方法对矿井水涌出的变化规律的预测是可行的,并有较好的预测精度和推广应用价值。
R/S analysis approach is a kind of non-linear theory one,based on the time-sequence data,which can be applied to analyze and predict the time-sequence data.In this paper,by means of the correct evaluation of Hurst exponent and fractal dimension,the author intends to analyze the changing patterns and spouting time-sequence,meanwhile to do a preliminary probe in the variation of inflow.The case study shows that this apporach owns a feasible prediction of the spouting variation in mine water,has a good predictable accuracy and poses the widespreadly applicable value.
