Abstract

In order to investigate the influence of mining back from the upper working face on the lower roadway, this paper takes the south roadway of the -655m level of Hebi 8 Mine as the research object, and studies the plastic damage characteristics of the roadway surrounding rock under the influence of mining disturbance of the 3107-working face in the south roadway of the -655m level. Through numerical simulation, this paper explores the stress distribution and plastic damage characteristics of the roadway peripheral rock in the -655m horizontal south roadway of Hebi eight mine, and clarifies the deformation and damage range of the roadway peripheral rock.

Keywords: Numerical Simulation, Ground Stress, Stress Distribution, Plastic Damage
