Mining Methods and Equipment School of Mechanical

Coal and iron ore, for example, typically occur in shallow-dipping stratified deposits. Thus mining benches can be designed to be long and straight, facilitating the use of an overland conveyor and minimising expensive crusher repositions. Deep gold and copper applications, however, require a high vertical rate of mining that in turn require crusher repositioning to be more frequent.
