摘　　要：以新河井田地质资料为基础,绘制了断层走向、倾向玫瑰花图和倾角分布直方图,表明井田内断层以SN和NE走向为主;利用断层分维值和断层影响因子指数对断层发育特征进行定量评价,对比两者的结果可以看出:后者在评价断层时考虑了断层规模大小,断层影响因子较大区域主要围绕两个大断层(嘉祥支和嘉祥支三断层)分布,大断层发育区岩层较破碎,导通的含水层越多,越容易引发矿井突水事故。On the basis of Xinhe mine geological data, making the faults strike/dip rose diagrams angle distribution histogram, indicates that the faults are mainly high angle normal faults with SN and and NE strikes, and analyses the fauhs mechanical reason. Quantificationally evaluated the faults developmental characteristics using the fault fractal dimension values and the fault influencing factor index. Comparing the results of the two： the fault size was taken into account in the latter one, the large areas of factor index distribute around two large faults （Jiaxiang branch and Jiaxiang branch three）, strata of large fault zones is bi：oken, the more aquifers were connected, the more likely to lead to mine water inrush accidents.
