Abstract:

Put forward three suggestions for reducing the mining stress concentration through theoretical analysis. Analyzed the status quo and improvement scheme of Zhazixi antimony mine by MIDAS-GTS and FLAC3D.The results showed that the stress concentration is obviously and not easy to predict under the status quo of disordered mining way.The stress concentration appeared for the first vein mining footwall and could be avoid better for vein mining on the plate first of improved scheme.So to prevent and control the rock burst by stress concentration of Zhazixi antimony mine should choose vein mining on the plate first.

Key words: rock burst, mining safety, stress concentration
