The challenge of ventilation - Guillermo Gaviria Echeverri tunnel

Since 2018, numerous challenges have been faced in constructing the Guillermo Gaviria Echeverri Tunnel (GGE) in the mountains of western Antioquia—a tunnel that will be the longest in the country and in all of the Americas.

Behind the drilling and ventilation of the GGE is Epiroc, a Swedish company and a global leader in the mining and construction industries. Epiroc's Boomer XE3C and Boomer E2C jumbos with ABC Total navigation systems have excavated approximately 1.4 million cubic meters of soil, facing varied rock quality (between Type 3 and Type 5 Special) and the inherent challenges of a project of this length, particularly ventilation.
