A miner climbs on excavated rocks after a giant Sissi drill machine broke through the last section of rock at the construction site of the NEAT Gotthard Base Tunnel in Switzerland on March 23, 2011. Crossing the Alps, the world's longest train tunnel consists of two, parallel, single-track tunnels, each a length of 35 miles. The project should become operational at the end of 2016.

TU Delft Mining Engineering (EMC) It is the job of the Mining Engineer to locate, quantify and produce mineral resources in an economical and sustainable manner. He/she needs to be adept in the geological and mineralogical aspects of resource deposits and familiar with highly sophisticated techniques. A good understanding of the related fields of mineral and metallurgical processing and the environmental and economic implications are also very important. The European Mining Course (EMC)
