探讨了煤层巷道巷旁煤柱及采空区冒落浮煤逾渗漏风裂隙的分形特征 。
The fractal fearure of percolation leakage crack in the pillars on sids of coal drift and caved coal in mined-out area is discussed,and the formation and expansion of percolation leakage crack ranging in a structural position of coal drift in one working face are also discussed and analysed.
