Simulation Analysis of Support Method and Parameters of Mine Roadway Based on GTS-NX
Taking Mozushao Phosphorite Mine as the research object,through numerical simulation analysis of Midas GTS-NX,simulation analysis of its deep roadway excavation and support,the results show that the support parameters corresponding to the three different support methods can be effective Reducing the distribution of surrounding rock plastic area and small set-tlement of the roadway roof indicates that the support design is reasonable,and at the same time,the distribution of the plastic area can be effectively eliminated through combined support;bolt support,shotcrete support and steel arch support support In contrast,the bolt support is an active support.The shotcrete and steel arch support are passive support,but the shotcrete sup-port effect is more obvious.In order to prevent the stress from being released immediately after the tunnel is excavated,each support work ensures With digging and supporting;as the burial depth of the ore body increases,the phenomenon of sheet walls and floor bulges experienced by deep tunnels becomes more pronounced.
