Object of research - processes of sedimentation iron-ore dust on the electrostatically charged fibres. Purpose - the increase of efficiency the dedusting air of workplaces on crush-sorting and mining and processing complexes by catching of dust a fibеr filter in aspiration shelters, decrease of dust sediments in aspiration pipelines, prevention of losses iron-ore raw material at his processing and transporting, decline of load on the filters of the aspiration-hauling installations. Methods of research: analysis and generalization of literary sources on the types and designs of dedusting devices in an aspiration shelters nodes overload of iron ore raw material; methods of mathematical statistics and statistical analysis for the valuation of dustiness air on working area and results of researches; methods of physical modeling for research of process bearing-out dust and determination of efficiency dedusting of fiber filter. Experimentally determined relations to the intensity bearing-out of dust from a distance installation fiber curtains in the gutter to the place of unloading rock mass from the upper bunker and from distances of fiber curtains to the place of fall the rock mass in the receiving bunker. Determined relations of efficiency dedusting of double fiber curtains from packing fibers on the curtain, size of the surface charge fiber curtains, distance between the fiber curtains of different sign of charge, quantity of fiber curtains, velocity of dusty air through the fiber curtains. The new construction of fiber filter is worked out for aspiration shelters of overload nodes, "Album of fiber filters" with the methods of choice parameters of fiber filters, methodical instructions for implementation of laboratory works. Carried out industrial research developed by the construction of fiber filter in the crush-sorting factory mine "Rodina" public joint stock company "Krivoj Rog's Iron-ore Combine", as well as building medium-fine crushing of a crush factory and concentrator 1 open joint-stock company "Poltava Mining". Novelty: determined relation of size intensity bearing-out of dust through fiber curtain from a distance her installation to the place of falling of mountain mass which submits a parabolic law, here the maximal decline of intensity takes place at distance within the limits of a 0,25-0,35 m; proven of efficiency besieging iron-ore dust within the limits of 31-32 % on kapron fibers with the most surface positive charge of 4,2 mkKl/m2 and within the limits of 27-28 % on polivinilchloride fibers with the most surface negative charge of 2,3 mkKl/m2; revealed relation of efficiency catching iron-ore dust in aspiration shelters, equipped two fiber curtains of a kapron and polivinilchloride of different sign of surface charge, from distance between them, at that most efficiency dedusting 67-68 % takes place at distance 0,05-0,15 m; shown of efficiency catching dust a fiber filter within the limits of 95-96 %, made from double kapron and polivinilchloride curtains, by turns set, in an amount not less 6 pcs. Introduced in industry and in the learning process. Branch use - mining.
