A Literature Review on Haulage Systems DiVA
网页The haulage system for ore and waste, one of the most important operations in underground mining, involves transportation of mined-out material from the faces (draw points) to the loading areas, and then to the mine surface (Atkinson, 1992). Material removed from the loading area can be transported vertically or horizontally to the surface.
