ABSTRACT: The article presents the results of the mineral and chemical study of basaltic rocks of the Selendumsky deposit with its further melting in electric arc plasma to generate melt, obtain stone cast and fibrous materials based on it. To conduct tests on melt generation the processing samples of the Selendumsky basalt deposit of Transbaikalia were used, sieve analysis of the samples showed that the main part of its mass is represented by particles ranging in size from 7.0 to 1.0 mm (90.35%). The study of basalt in thin sections revealed that there are lenticular textures leading to the appearance of small zones of tectonic crushing and cataclase. The studies of the mineral and chemical composition revealed that in obtaining of the melt and generating of the mineral fiber composition from it the Selendumsky basalt for its composition is included in the following limits: SiO2 47,5-55,0; l4,0-20,0 Al2O3; 3,0-8,5 MgO; 7, -11.0 CaO; other rocks (no more than 5%). For the research on the generation of basalt melts an electromagnetic process reactor with working regimes of melting was applied. When studying the melting mechanism of the raw material using the electric arc melting apparatus a simulation environment was used in terms of the TEPPA computer program.
