Title: Study on Stability Effect of Large Diameter Deep Hole Mine Blasting Vibration on Surrounding Rock of Mining Tunnel
Abstract: In order to study the impact of blasting vibration on surrounding rock of mining tunnel by large diameter deep hole blasting in mining operation.The FLAC3D 3.0 was chosed as basic computing tools based on the actual blasting vibration loading.From the stress and deformation of mining tunnel,the condition and its changes of stress,deformation and plastic zone of surronnding rock in tunnel under blasting vibration loading was researched,and finally the impact of large diameter deep hole blasting vibration on surrounding rock of mining tunnel.In the process of simulation,the corresponding changes of monitoring points show the impact characteristic of blasting vibration on surrounding rock.
