Earth miners play a crucial role in the mining industry because these machines are designed to facilitate large mining and earth-moving projects. Along with the specialised skills of the operator, pushing material, scooping loose soil, and removing material are done by using earth movers. Earth movers work in close tandem with bulldozers.
