摘　　要：在疏放控水初步降低水位后,采用模型试验和数值模拟分析第四系底粘土的采动变形破坏特征和隔水性。总结了底粘土采动变形、裂隙发育及裂隙粘土渗透性规律,提出微裂隙底粘土仍作为保护层一部分的主要结论。After earlier decline methods are used to of water level caused by dewatering, model test and numerical simulation analyze the characteristics of clay layer at the bottom of Quaternary system, including deformation, breakage and water-resistance during mining. Based on this the regulation of bonom clay deformation, development of fractured zone and seepage of failure clay layer is summarized. And the bottom clay layer with micro-fissures can be regarded as part of water-re sisting layer is them put forward.
