Abstract: | Adopting FLAC 3D , the effect of top-coal thickness in second miming on the parameters such as roof-floor displacements, maximum and minimum principle stresses and their evolution laws are studied in this paper The simulation results provide the theoretical basis for the determination of top-coal thickness and the success mining. |
