| 摘 要： | 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

| Abstract: | The current methods for predicting mining subsidence are based on the linear distribution about main section of face,and the considerable predicting error could be occured in mining coal seams with monlinear distribution. Based on the stochastic medium theory,this paper deduces predicting formulas of ground movement and deformation with the aid of the method of curvilinear integral,computes the values of ground movement and deformation by way of the method of numerical integral and the overlap principle.As a result,applied range of the subsidence predicting theory can be widened,and the precision of predicting results also improved. |
