underground lode (hard rock) miningthere are five steps in development mining remove previously blasted material (muck out round), drill rock face, load explosives, blast explosives, and support excavation. production mining is further broken down into two methods, long hole and short hole. short hole mining is similar to development mining, except that it occurs in ore.

lhd (load, haul, dump machine) lhd loaders are similar to conventional front end loaders but developed for the toughest of hard rock mining applications, with overall production economy, safety and reliability in mind. they are extremely rugged, highly maneuverable and exceptionally productive. more than 75% of world's underground metal mines use lhd for handling the muck of their excavations.
