摘　　要：阐述了采煤过程中底板岩层在矿压作用下的变形特征及其规律。在理论上提出了当倾向采场且平行其边缘的底板断层面同底板岩层中的最大膨胀线相吻合时，该类断层两盘的相对位移量最大，也最容易发生突水事故，并通过实例说明了底板断层的突水机理。最后，从水文地质和采煤方法两个方面，提出了防治突水的措施。This paper describes characteristics and regularity of deformation of floor rocks under ground pressure. It is pointed out in theory that the relative displacement of two walls of the fault is maximum, when the fault surface,which inclines to the workings and is parallel to the edge of the workings, is in coincidence with the maximum swell line in the floor strata. In such case, the water inrush may occur. The mechanism of water inrush from the fault in the floor is illustrated with examples. Finally, the measures for prevention and control of water inrush are proposed from the view point of hydrogeology and mining method.
