                Load-Haul-Dump (LHD) machines in mining

     Diesel-driven LHDs are versatile and flexible in mining. They are used in
several tasks in addition to production and development, such as cleaning the
roads, material haulage etc. The loading system and the use of LHD machines
greatly depend on the mining method. Loading from a stope into a primary
crusher is usually done in one or two stages. The most common ways of loading
and transporting in an underground mine are:
     • Loading with an LHD from a stope or through draw points into the ore
pass. The haulage distance is usually between 50 and 400 meters. Further load-
ing with LHDs from the ore pass into the crusher, or chute loading into a train or
a conveyor belt, which transports the ore straight to the crushing plant or into the
ore pass which leads to the crushing plant
     • Loading from a stope straight into the crusher or into the ore pass that
leads to the crushing plant. Tramming distance is usually between 50 and 400
meters, but longer distances are also used.
     • Loading from a stope into dump trucks, which transport the ore to the
crusher or to the ore pass leading to the crushing plant. Tramming distance is
usually under 100 meters.
     • Loading from a stope into a train or a conveyor belt, which transports the
ore pass, or straight to the crushing plant.
