大采深全断面地表沉陷预测模型研究

应用弹性板理论，建立了开采沉陷中全断面大采深地表预测基本模型，在此基础上导出了走向和倾向主断面的预计模型以及任意点的下沉、倾斜、曲率、水平移动和水平变形预测函数，并讨论了预测中所采用一些参数的计算方法．结果表明，用弹性板理论建立的预计模型具有与其它模型相似的性质，并且简单、直观、易用，克服了以往预计模型的不足，更好地符合现场实际．最后，用实例证明了该模型的应用效果．

Study of Ground Subsidence Prediction Model for Full Section and Deep Mining

Ground subsidence prediction model for full section and deep mining was established by using the elastic plate theory.On the basis of this,deformation prediction models for main sectional planes in both strike and dip directions were deduced and the subsidence,inclination,curvature,horizontal displacement,horizontal deformation prediction functions at random points were calculated.In addition,some parameters in predicting model were also discussed.The results show that this prediction model has a similar characteristic to other ones and is intuitive,simple and easy to use,coincident with the practical conditions in-situ.The effect of the prediction model was proved good with a practical example.
