Loading and haulage
The need for mechanized underground mining and development operations
has led to the ever-growing use of trackless equipment. There are multiple track-
less choices available in loading and haulage today. Front-end loaders and LHD
(Load-Haul-Dump) machines are the two most used alternatives. The LHD have
proven to be the most successful alternative, especially in underground mining.
The LHDs have the capability to climb steep terrains, move fast over long dis-
tances and their outer dimensions are favorable to underground mining opera-
tions. LHD technology has increased the productivity and mechanization level
in different applications. Front-end loaders have been more popular in surface
excavations. In addition, the constructing industry, in large excavation has used
more front-end loaders than LHD. However, LHD technology gives the advan-
tage of using same loading units at different excavation sites in underground
construction, and thus makes it more versatile and powerful in these applica-
tions.
