摘　　要：介绍了多重分形的概念 ,在Chhabra和Jensen提出直接法的基础上 ,给出了以矿井涌水量时间序列的功率谱函数为特征量的多重分形谱的计算方法和步骤 .利用 6个矿井涌水量的实测数据对该方法的可行性和有效性进行了验证 ,同时说明了矿区地下水系统具有多重分形的特征 .On the basis of introducing the multifractals concept,power spectrum of mine hydraulic discharge act as a characteristic quantify is put forward,in order that the multifractal spectrum from time series of mine hydraulic discharge is calculated combining with Chhabra and Jensen put up instant calculating method. As a means of method on the calculating multifractal spectrum from time series of mine hydraulic discharge,each and every multifractal spectrum is obtained by use of actual measured value of mine hydraulic discharge from six shafts,they are proved not only feasibility and validity but also multifractals character of groundwater system in mining areas.
