One of the effective ways of overburden transportation at open pits is hydraulic transportation. Application of this method in the period of quarry operation is sometimes difficult due to the presence in the quarry of other technological schemes with the use of dry mining equipment or complicated mining and technical conditions. At the same time, when using only dry mining equipment, it is not always possible to solve the whole complex of problems associated with excavation, transportation and stacking of rocks in dumps at a high technical and economic level.
