现行的地表移动预计方法，都是建立在开采工作面主断面为线性分布的基础上，因此，对于非线性分布煤层的预计将会产生较大的误差。本文以随机介质理论为基础，利用曲线积分的方法建立了地表移动与变形预计公式，并且利用数值积分法和叠加原理解算地表移动与变形值，扩大了地表移动预计理论的应用范围，同时也大大提高了预计值的精度 The current methods of predicting surface movement are all based on the linear distribution of the main section of the mining working face. Therefore, the prediction of the coal seam with nonlinear distribution will produce large errors. Based on the theory of stochastic medium, the prediction formula of surface movement and deformation is established by the method of curve integral. The numerical integration and superposition principle are used to calculate the movement and deformation of the earth’s surface, which expands the application range of the theory of surface movement prediction. Greatly improve the accuracy of the expected value
