煤矿中断层构造对开采条件、瓦斯突出、矿井突水等都有显著的影响。以陈四楼煤矿为例,利用分形理论计算了深部采区断层构造的分维,对断层构造的复杂程度进行了讨论和划分;分析了不同区域断层构造分维值出现差异的原因;建立了断层构造分维与矿井突水单位涌水量的对应关系,随断层分维的增加,矿井突水的单位涌水量也将随之增大。研究区的断层分维在0.7925~1.4534,断层总体的复杂程度为中等。
煤礦中斷層構造對開採條件、瓦斯突齣、礦井突水等都有顯著的影響。以陳四樓煤礦為例,利用分形理論計算瞭深部採區斷層構造的分維,對斷層構造的複雜程度進行瞭討論和劃分;分析瞭不同區域斷層構造分維值齣現差異的原因;建立瞭斷層構造分維與礦井突水單位湧水量的對應關繫,隨斷層分維的增加,礦井突水的單位湧水量也將隨之增大。研究區的斷層分維在0.7925~1.4534,斷層總體的複雜程度為中等。

In coal mines,faults structurces have a significant impact for mining conditions,gas outburst,and mine water inrush.Based on data from Chensilou Coal Mine,this paper computed the fractal dimension of faults structures(Ds) in deep mining area,discussed and divided the structures complexity of faults structures,analyzed the differences of Ds in different regions via fractal theory.The results allowed us to draw the following conclusions.(1) The values of Ds are between 0.7925 and 1.4534,and the overall complexity of the fault structures is medium in the study area.(2) We find that mine water inrush will be greater with Ds increases,and the function between Ds and mine water inrush is established.
