STEMMING MACHINE FOR FORMATION OF SHORT COMBINED STEMMING OF BLAST HOLES WITH STONE MATERIAL

摘要

FIELD: mining.;SUBSTANCE: invention relates to drilling and blasting operations and can be used in various industries, using explosive loosening of rock massifs. In stemming machine for formation of short combined stemming of blast holes with stone material, equipped with hydraulic grab-manipulator and two hoppers with heating and vibration of walls, on bottoms of which there are plate-type feeders, feeding stemming material, according to invention, fine and lumpy materials are placed in different hoppers, and are fed to a common rotary chute pivoted in lower part of hoppers.;EFFECT: higher efficiency and reduced labour intensiveness of works during formation of short combined stemming of wells by mechanising process of arrangement of stemming material.;1 cl, 3 dwg
