| 摘 要： | 该文通过对皖北刘桥矿区4、6煤层顶板部分钻孔岩芯裂隙统计,基于岩石质量指标并不能很好反映沿钻孔裂隙间距(结构面密度)的变化、块度的大小以及对小于10cm薄弱带的信息反映不够,该文运用分形理论的方法对刘桥矿区4、6煤层顶板岩体质量进行了定量评价。结果表明,分维值能够较好地反映煤层顶板的岩体质量。

| Abstract: | Through the statistics of drilling core fracture in parts of the 4th,6th coal seams roof of Liuqiao mine area,based on the RQD couldn't reflect the distance changes of the drilling core fracture,the size of mass and the information of less than 10cm weak strip,the paper quantitatively evaluates the rock quality in parts of the 4th,6th coal seams roof of Liuqiao mine area by fractal theory.The results show that fractal dimension values can reflect rock mass quality of coal seams roof. |
