APPLICABILITY OF BOTTOM TRAWL TO LARGE-SCALE SAMPLING OF DEEP-SEA FERRO-MANGANESE NODULES

Features of geological exploration of deep-sea nodule fields are discussed. The basic methods and equipment for sampling ferro-manganese nodules are described. The article puts forward a bottom trawl designed for the large-scale sampling of nodule fields and presents calculated data for application domain of the trawl.
Ferromanganese formations of the bottom of the oceans are considered as mineral raw materials of the future, and near future, in addition, IMC are excellent sorbent for wastewater treatment from ions of metals in the metallurgical industry, etc. When planning the possibility and magnitude of cluster trailing you must consider a number of natural and technological factors. To the natural factors, in the first place, are the depth and density of occurrence of IMC, their granulometric composition, bottom topography, composition and properties of the host rocks and the depth of immersion in these nodules, and weather conditions; to technological – productivity of the complex. In studies of deposits of ferromanganese nodules the main objective (as with the production of geological exploration on the continental mineral deposits) is to obtain the most possible and accurate information with a minimal amount of work and time is close to instantaneous.

Keywords

Ferro-manganese nodules, sampling, deep-sea mineral deposits, bottom trawl, occurrence density, geological exploration efficiency.
