Improvement of Technology for the Development of Dredgers for Underwater Work and Mining.

Abstract For the current period of time, the existing technologies for underwater operations and mining have a number of shortcomings. Existing dredgers have limitations in the amount of pumped liquids, depth of development, conditions where these devices can be used. Many types of dredgers can be used for mining, cleaning the world's oceans and small ponds from accumulated debris. The working bodies of the dredgers themselves also have limitations in work, which, due to the use of the wrong materials, cannot work with hard soils or have a short service life.
