Some methodological drilling: Blasting parameters in the excavation of tunnel [PDF]
Podzemni radovi, 2017 The method of excavation tunnels, as infernal object depends primarily on the rock mass along the tunnel route, as well as rock mass in the nearby environment of the route. This paper presents a methodology for determining the drilling - blasting parameters in one of the various zones along the route of the tunnel.

Mechanism of surrounding rock failure in impact stress and in-situ stress in circular tunnel
Geomechanics and Geophysics for Geo-Energy and Geo-Resources, 2023 With depth increase of many mines, the damage of surrounding rock by high ground stress cannot be ignored under the blasting excavation method. In view of the strong disturbance of surrounding rock caused by dynamic excavation and unloading under high ...
