采动过程中地表移动变形计算研究

Computation Study of Ground Movement and Defor-mation during Mining Process

本文把地表点的移动过程看成是时间的函数，利用负指数推导出采动过程中地表点的移动变形计算公式。经实测验证说明，这种方法能够较准确地反映地表点的移动过程。

The pro-cess of movement of a surface point is regarded as a function of time. The formula for calculating the movement and deformation of the surface point dur-ing mining are derived with the negative exponent. As evidenced by field observation the method used can present a comparatively accurate picture of the move-ment process of the point of interest.
