Abstract

In this article, new classification features of machines for underwater mining of solid minerals are proposed, such as their cyclical and continuous operation. It is established that for cyclical machines starting from a depth of 300…500 m the speed of movement of the executive body (trawl, drag, etc.) and the concentration of minerals do not have a determining value. When selecting equipment for underwater mining at a depth of more than 100 m and forecasting its performance, it is proposed to take into account the depth of development for cyclical machines, the speed of lifting and lowering of the executive body, and for continuous machines, reliability indicators, for example, the readiness coefficient determined by expert means.
