摘要
探讨了煤层巷道巷帮煤体及采空区冒落煤体逾渗漏风裂隙的分形特征,并对东滩煤矿43_上08工作面煤层巷道构造位置逾渗裂隙的形成与扩展情况进行了分析和讨论。
In this paper, the author discussed the fractal features of percolation leakage crack in the damaged pillars of the sub-level caving mining roadway. The fractal features of the damaged coal in the mined-out area are also mentioned. Moreover, the producing and opening situation of percolation crack at the fault area in the 4308 caving roadway in Dong-tan coal mine is intro-duced.
