Tunnelling under strict seismic regime on tunnels "Veliki Gložac" and "Zaranač"

Tunnell excavation by drill+blast is often limited when the new tunnels have to be excavated close to the existing tunnels in traffic, or in urban areas. Controlled blasting with constant seismic monitoring can be applied very efficiently with good advance rates and with no damage to surrounding objects. Recent examples of excavating two tunnels show general principle how to manage this problem.
