摘要
煤矿断层密度是评价煤层破坏程度的一个常用指标。由于它是单因素评价,所以在实际应用中往往受到限制。文中以平顶山五矿戊9 -10 煤层断层为例,采用分维计算方法对断层密度进行了重新定量,结果表明,断层密度分维与断层长度、条数和断层密度分布的均一性有关,它为煤矿断层密度的定量评价提供了一种新的方法。
Fault density in coal mine is a general being used index to evaluate the destructive degree of coal seam.Nevertheless,it is always limited in practice because it is a single factor evaluation.In tyis paper,a new method to quantify the fault density is presented by using fractal dimension calculation(as an example,all data come from Coalbed 9-10 in Coal Mine No.5,Pingdingshan).The results show that there is a relationship between the fractal dimension of fault density and the length,number of fault as well as homogeneity of fault density distribution.The fractal dimension of fault density can provide a new method to evaluate the fault density in coal mine.
