摘　　要：通过对芦岭矿 810采区四含渗透性的测试 ,分析了粗颗粒含量与渗透系数、破坏水力梯度之间的关系 ,指出了在采动裂隙和原生裂隙波及四含时 ,四含土体会产生管涌型破坏 ,并在现场观测中得到了验证。With the test and measurement of the permeability of the Quaternary aquifer in No. 810 mining block of Luling Mine, the paper analyzed the relationship between the coarse particle content and the permeability coefficient and the relationship between the coarse particle content and the destructive hydraulic gradient. The paper pointed out that a tube inrush type failure could be occurred in the soil mass of the Quaternary aquifer and had been approved when the mining cracks and primary cracks reached the Quaternary aquifer.
