摘要
将层状岩体视为各向同性材料，采用富氏积分变换得出了水平煤层开采覆岩离层的解析表达式。同时，采用动态模型辨识和参数识别方法、相似材料模拟方法，并结合部分实测资料，对采动覆岩离层的动态发育规律进行了探讨。
The stratified rockmass was regarded as an isotropic medium, and an analytic expression for separation of overlying strata in mining a flat coal seam was obtained by using Fourier integral transformation. At the same time, the dynamic process of rock separation was studied by using a dynamic model and parameter identification, simulation test with equivalent materials and checked with some measured data.
