| 摘 要： | 为了研究煤层底板承压水导升规律,基于流固耦合理论,在对煤层底板突水机理进行分析的前提下,建立了煤层底板突水的水文地质物理概念模型和数值模型,模拟了在不同方案下(不同的底板隔水层渗透系数、不同底板水压)原始导升高度与再导升高度的变化规律。

| Abstract: | In order to study the law of coal floor confined water conductivity, based on the fluid-solid coupling theory, under the premise of analysis of the coal floor water inrush mechanism, a hydrogeological conceptual model and numerical models of coal floor water inrush was established. Simulated under different scenarios(different floor aquiclude permeability coefficient, different bottom pressure)of the law of original water conducting height and water further conducting height. |
