中文摘要：

以平煤七矿为例，利用分形理论计算了二1煤层底板断层构造的分维，与不同区域的研究成果进行对比，讨论了断层构造复杂程度并对其进行了划分，利用Surfei.绘图软件，绘制了断层分维的等值线图。结果显示，平煤七矿断层分维值为0.7295~1.7297,断层总体复杂程度较复杂。本研究对矿井安全生产及水害防治具有借鉴价值。

英文摘要：

Using fractal theory, based on data from the No. 7 mine of Pingdingshan, the fractal dimension of faults structures ( Ds) in II-l coal bed was computed, and the structures complexity of faults structures was analyzed and divided. Then the contour map of Ds was drawn by using Surfer software. The result showed that the mine water irruption rate was found to increase with the fractal dimension. The values of Ds are between 0. 729 5 and 1.729 7 ,and the overall complexity of the fault structures is more complex in the study area. This study has a positive reference for controlling coal mine flood.
