摘要
为界定煤矿井范围内断层的性质,本文应用瞬变电磁勘探资料阐明了断层导水性,基于分形理论评价了断层复杂程度。研究表明:刘庄正断层具有较强的导水性,徐庄正断层表现为阻水性质,其余断层展现为弱导水特征;断层分形维数平均值为1.118,复杂程度整体表现为中等;刘庄正断层附近巷道掘进和工作面回采时应加强底板水害防治。
In order to define the nature of faults in coal mine range,the transient electromagnetic exploration data is used to clarify the fault hydraulic conductivity,and the fault complexity is evaluated based on the fractal theory.The research shows that Liuzhuang normal fault has strong water conductivity,Xuzhuang normal fault shows water blocking properties,and the remaining faults show weak water conductivity characteristics;the average value of fault fractal dimension is 1.118,the overall complexity is medium;prevention and control of floor water disaster should be strengthened in roadway excavation and mining face near Liuzhuang normal fault.
