FIELD: production of heat-insulating materials. SUBSTANCE: feedstock for producing mineral fibers with low-temperature plasma contains the following components, pts wt: ash of thermal power stations, 42.0-50.0; waste of mining industry, 28.0-32.0; correcting addition, 2.0-10.0; binder, 6.0-10.0; water, the balance. Diameter of produced fibers is 5.6-6.6 microns. Feedstock allows using readily- available kinds of ash which favours reducing environmental pollution by eliminating dumps of waste. EFFECT: improved production procedures. 3 tbl
