摘要
Abstract
In order to modify surface subsidence problem, authors used software Flac3dand did research on surface subsidence law of different mining range and iflling rates. The results show that with the working surface advancing, the surface subsidence parameters gradually increase, but the increment decreases gradually with 80% ifll rate.When the distance is 800m, the surface subsidence decreases with the iflling rate increasing.The parameters such as sink value, tilt, curvature, horizontal movement and horizontal deformation gradually decrease, and the decrease gradually increases.关键词
