Surface Mining & Excavation Machines

Traditional surface mining has left untold tons of minerals underground, simply because there was no way to get to it safely and efficiently. The Vermeer innovative Terrain Leveler ® surface excavation machines can work where explosives can''t, with top-down cutting that lets you reach valuable mineral seams and get the most product out of the ground as possible.
