Surface excavation machines (SEMs), like the Vermeer Terrain Leveler SEM, use top-down cutting that allows the operator to separate materials, extract higher value and more consistent sized product. The end product reduces the need for a primary crusher, reducing energy and expenses. Also, surface excavation equipment is more environmentally friendly than traditional methods. Mining operations can significantly reduce the amount of explosives they use, which helps reduce the amount of dust and vibration produced. They are also able to comply with more stringent government regulations affecting drilling and blasting methods.
