GEOINFORMATION SEARCH OF IMPORT-SUBSTITUTING RAW MATERIALS FOR WATERJET CUTTING OF MATERIALS

Abstract

The main objective of the mining industry is to provide the industries with raw materials for manufacturing the finished products or for operating tools in processing the materials. The waterjet cutting currently uses powders of carbide alloys, carbides, oxides and pomegranate sands as an abrasive. The latter are purchased abroad. The paper describes the main properties of sands and possible ways of import substitution, which allowed on the basis of geoinformation support for some deposits to reveal attribute features of sands and grinding products for use as an abrasive. The pilot tests on the use of shredded waste and natural sands as an abrasive have been carried out at a number of machine-building and stone cutting enterprises of the Urals. As a result, we have given the preliminary recommendations and indicated the ways to assess the efficiency of using the domestic mineral raw materials as an
abrasive in the waterjet cutting of materials.
