Abstract: Combing with the field practice, the theoretical analysis method and numerical simulation method are adopted to analyze occurrence mechanism of the impact ground pressure of the deep irregular island mining face and explore the prevention and control technique of the impact ground pressure of the deep irregular island mining face. The working face roadways are deployed in low stress areas and the unloading lanes are diverted in irregular areas so as to form stress buffer to prevent and control the impact ground pressure. The research results of this paper can provide some reference for the design of irregular island mining face in deep mine.

Key words: Irregular island mining face, Impact ground pressure, Prevention and control technique
