The thesis is devoted to determining the parameters of the bucket to increase productivity of dredgers while mining deep-water organic-mineral sediments. It was achieved by increasing the fill factor through determining the rational geometrical parameters of the bucket. Analytical dependencies of the rational height and length of the bucket on the cutting parameters and physical-and-mechanical properties of the excavated sediments were determined. Expressions for defining forces while digging plasticity water-saturated soils were developed. Experimental investigations of the process of digging deep-water organic-mineral sediments in laboratory conditions and in the real conditions of operating single-bucket dredger in the Black Sea at the depth of 1885 m were carried out. The technique for calculation of the bucket\'s parameters was developed.
