FIELD: mining.
SUBSTANCE: method for producing fibres from mine rock involves crushing of mine rock till granules of the specified size are obtained, supply of crushed rock to zone of melting and drawing of the fibre from the melt. At that, graded granules are produced during rock crushing process; melting zone is made so that it is extended along vertical axis; graded granules are lowered in turn under action of their gravity force into melting zone, and fibre is drawn from the melt of each graded granule.
EFFECT: improvement of method.
