摘　　要：通过分析我国煤矿底板突水的基本特点,探讨了其底板突水机理,将煤矿底板突水划分为两大类型,即构造底板突水、工程扰动底板突水。从底板受力和破坏形式的差异出发,将底板分为"三区"和"五带"。运用箱体模型解释了地下水不同储水带、导水带间的径流、补给及排泄现象。Through the analysis of basic characteristics of water inrush from coal seam floor and discusses mechanism of water inrush from coal seam floor,water-inrush is divided into two types：water inrush from coal seam floor led by geologic structure and water inrush from coal seam floor led by engineering disturbance.According to the difference of the force of coal floor and failure forms,coal seam floor is divided into Three Districts and Five Bands.The Box Model can be established to explain the phenomenon of runoff,supply and excretion between different water belts and water flowing fracture of groundwater.
