Characteristics, relative economics and applications of hydraulic cutter head dredge and bucket line dredge (ladder dredge) as mining tools; outline of basic operating principles of continuous feed machines; it is shown that dredge is capable of selective mining where mineral deposit may occur in multiple bedding planes; type of dredge to be considered depends on total depth of deposit, bed thicknesses, dip of ore beds, and nature of materials to be mined.
