根据大量的突水资料分析认为,底板突水与:(1)底板承压水的水压、水量;(2)底板隔水层的厚度、岩性及其组合结构;(3)底板地质构造及承压水沿构造裂隙上升的高度(称其为“原始导高”或“隐伏水头”)以及(4)采矿活动矿压对底板破坏的深度和强度等因素的综合作用有关。近期研究认为,后二因素是最直接因素。查明、控制或改造这些因素,是预防底板突水的关键。
According to a large number of water inrush data that the floor water inrush and: (1) floor pressure of water pressure, water; (2) the floor aquaculture layer thickness, lithology and composite structure; (3) floor geological structure And the combined effects of confined water rise along the structural fissure (called “original” or “hidden head”) and (4) the combined effect of mine rock pressure on the depth and strength of the floor. Recent studies suggest that the latter two factors are the most direct factor. Identifying, controlling or modifying these factors is the key to preventing water bursting from the floor.
