摘要
大量的开采实践证明,采动上覆岩层的一定范围及地表的移动变形具有流变特性,这种特性是地表动态移动变形的主导因素。作者以Knothe理论为基础,通过Zero模型,建立覆岩移动变形的流变模型,分析地表动态移动变形特性,给出地表动态下沉盆地的移动变形预计理论及其参数。
Many of mining practice proved that the range of overlying strata and surface displacement and deformation have creep characteristics. It is the main factor of dynamic displacement and deformation. The article based on Knothe theory, and completes the theological model about overlying strata displacement and deformation by Zero model, and analyses the surface dynamic movement and deformation characteristics. Given the prediction theory and the parameters of dynamic displacement.
