We can look the stratum movement and subsidence as a whole system to study. The common nature of stratum movement and the development procedure of crack arch are described. Meanwhile
based on the ground observation by the global positioning system (GPS)
the boundary angle and the motion angle
which aim at special geologic conditions
are determined. The relation between the position of underground working face and ground subsidence velocity are found.
