The fascination of tunneling with compact components
Tunnel builders can be dealing with vastly different substrates. Mostly, however, he drills and blasts rock. Digging deep has become a relatively safe, high-tech process. Today, gigantic tunnel boring machines, often operated by just one expert, do the painstaking work. Driving up to 40 meters a day, they work their way through rock or silt almost independently.
At the same time, they secure the tunnel walls with steel arches and line them with a layer of concrete. Drainage systems built in parallel drain water out of the mountain. However, blasting still takes place in the same way. Several successful projects have shown that these conveyor belt systems are very suitable and cost-effective alternatives to track-bound overburden trucks for the removal of rock, as they enable very good performance due to high system availability, as well as high operational reliability and high load-bearing capacity.
