不同应力环境下回采巷道围岩稳定性模拟研究
Simulation Research on Surrounding Rock Stability in Stoping Roadways under Different Stress Environments
摘要
Abstract
To study the impact of stress on the surrounding rock stability in stoping roadways,numerical simulation software is adopted to carry out research on the distribution characteristics of stress,displacement,and plastic zone of surrounding rock in stoping roadways under different stress environments.The results show that the vertical stress of the roadway after excavation presents a concentration feature in the horizontal direction,and the concentration value gradually increases with the increase of mining stress coefficient and lateral pressure coefficient;Different degrees of deformation appear around the roadway.With the increase of mining stress coefficient,the displacement of the roadway roof and floor gradually increases,and the displacement of the two sides first decreases and then increases;With the increase of lateral pressure coefficient,the displacement of roadway roof and floor first decreases and then increases,and the displacement of both sides gradually increases;The range of plastic zone increases with the increase of mining stress coefficient and lateral pressure coefficient.The field ground pressure monitoring results verify the rationality of roadway support parameters,and it is expected that the research results can provide a reference for roadway stability in complex environments.关键词
