Analysis of Instability Mechanism Ore Hauling Tunnel in Lanjian Iron Mine 1~#、3~# and Engineering Control
To the instability phenomenon appeared at haulage tunnel local section of a mine,simulation was done by using finite element numerical,effects from continuously decreased mining level,open pit blasting vibration were considered,combining prestressed anchor cable and steel arch support effect were analyzed,provided a certain reference for similar tunnel analysis.
