Diesel-powered loaders are a pillar of modern underground
metal mining. As these mines are getting deeper and hotter and the emission
regulations stricter, ventilation costs are soaring, affecting production cost.
Also, the cost of diesel fuel is expected to rise. These may make the use of
diesel engines more problematic. Electric load-haul-dump machines (LHDs) are an
interesting alternative. This paper compares features and performance of diesel
and electric, cable-powered LHDs. It overviews equipment offerings, and
compares, analyzes and discusses technical parameters, operational problems and
cost issues. The paper gives some conclusions about electric LHD applicability
and performance, indicates possible applications, and suggests further research
