| Abstract: | 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. |

| Keywords: | under unconsolidated water-bearing strata bottom clay deformation and breakage fissures closure protect layer |
