Abstract: Simulation analysis were done on breaking arch developing and evolving process of both single stope and compound mining field by FLAC3D, evolution law and change shape of breaking arch at stope upper part of short distance coal seams uplink stope structure space under single stope and compound mining field two different situations were obtained.

Key words: Short distance coal seams, Ascending mining, Breaking arch, Stope structure space, Evolution law, Numerical simulation
