Abstract:Aiming at the rock burst in roadway under the complex conditions in deep mine, theoretical research was carried out on the stope overlying strata structure, obtaining abutment pressure distribution characteristics of the working face; stress distribution characteristics of the working face surrounding rocks were ascertained with numerical simulation. Large-hole drilling and deep hole blasting were applied in the high rock burst risk area, and an anti-scour yield support technology was employed using anti-scour yieldable bolt. The industrial test showed that the technology effectively solved the rock burst problem for roadway under complex mining conditions and ensured the safe and efficient production.
