The Minnesota Department of Transportation (MnDOT) relocated a portion of T.H. 53 between Eveleth and Virginia, MN. The preferred alignment crosses the existing Rouchleau iron ore pit on a 1,100-foot bridge. Two abutments and one pier of the bridge will be founded on bedrock. Future iron ore mining adjacent to the alignment will create rock slopes up to 500 ft high. After mining, the new roadway will be atop a trapezoidal cross-section 300 ft wide at the top and with downslopes of about 53 degrees.
Join nearly 1,600 blasters, manufacturers, government officials and industry leaders at the world’s largest conference on explosives engineering, sponsored by the International Society of Explosives Engineers.
Miss Aravena has worked in various projects focused on underground and open pit mining. These mainly focus on developments of geotechnical models, structural and geological studies.
