陈四楼煤矿南部深部采区的断层构造较多,是煤矿深部煤层开采突水的重要影响因素,通过对南部深部采区断层的非线性量化分析,获得研究区断层的分维值平均为1.10,在0.7925~1.4534之间,断层构造复杂程度为中等.并获得了研究区突水的单位涌水量与断层构造分维之间的关系,且随着断层分维的增大,矿井突水的单位涌水量也会增大.
陳四樓煤礦南部深部採區的斷層構造較多,是煤礦深部煤層開採突水的重要影響因素,通過對南部深部採區斷層的非線性量化分析,穫得研究區斷層的分維值平均為1.10,在0.7925~1.4534之間,斷層構造複雜程度為中等.併穫得瞭研究區突水的單位湧水量與斷層構造分維之間的關繫,且隨著斷層分維的增大,礦井突水的單位湧水量也會增大.

There are many fault structures in deep mining areas within Chensilou southern coal mine that are affected by water inGflows within deep coal mining areas.Nonlinear quantitaG tive analysis has been conducted within these faults.The results showed that the faults'average fractal dimension is 1.10.Between the range of 0.7925~1.4534,the fault structure degree of complexity was considered medium.The relationship between the volume of water inGflow and fault fractal dimensions have been obtained.The results indicate that with increasing fault fractal dimensions,the volume of water inGflow will also increase.
