Both LHDs and mining trucks (figure 2) can be used in underground mines and fitted with automatic systems. However, while the former have a bucket and can therefore load the ore/minerals, the latter can be used only for transportation. In open cast mining, it is common to use larger trucks than those used in underground mines.
