    Economic evaluation of optimum bench height in quarries

    economical bench height has been suggested to be 12 m (Lechner, 1971). Today, bench height can be designed up to 15 m in large quarries, while it can be 12 m in small ones. Moreover, in small open pit gold mines it is feasible to design bench heights up to 7.5 m since it requires selective mining and the achievement of less dilution (Hustrulid and
