摘要:This paper aims to solve the problem of roadway rock burst under the complex deep mining conditions. The abutment pressure distribution characteristics of the working face were simulated based on the theoretical study of stope overburden structure. The stress distribution characteristics of the working face surrounding rocks were ascertained by the FLAC3D numerical simulation. According to the results above, the roadway rock burst risk area was predicted based on the occurrence mechanism of rock burst. However, the idea effect can't achieved only by the previous rock burst control measures in high impact risk area. Therefore, an anti-scour yield support technology was studied to adapt to the roadway deformation and avoid support system failure. The industrial test was carried out in the No.113L09 working face crossheading of Ji-er coal mine. The results showed that the anti-scour yield support technology could effectively solve the problem of roadway rock burst under the complex mining conditions and ensure the mine safety and efficient production. © 2015 ejge.
