Numerical Simulation Study on Mining Subsidence Laws in Licun Mine

Ground movement and deformation caused by mining work of 8301 working face in Licun Mine is simulated by using software FLAC^3D .With the observation and analysis of surface subsidence, tilt deformation, the horizontal movement and the horizontal deformation four aspects, basic laws of ground subsidence caused by coal mining is obtained, which provides a theoretical basis for controlling surface subsidence.
