Basics of an open pit mine mine engineerDesign of Surface Mine Haulage Roads A Manual

Open pit mines can be used in coal mining and they are used extensively in hard rock mining for ores such as metal ores copper gold iron aluminum and many minerals In a open pit coal mine the pit bottom would be the bottom mined coal seam elevation since it is usually feasible to extract multiple seams when surface mining coaluse and control components Thus designing haulage roads to accommodate these vehicles leaves a wide margin of safety for all other surface mining equipment Extensive engineering data for all makes and models of large off the road haulage vehicles was solicited from manufacturers
