Abstract: Three-dimensional finite-difference calculation method was used to analyze the mechanical process of deep development of mine. Then, the mining history, the stresses, displacement and destruction of the surrounding rocks after technical reconstruction were compared, and the potential happening possibility and place of ground pressure disaster after deep development were forecasted. Finally, the viable technical measures were given.
