METHOD OF ROCK MASSIF DISINTEGRATION BY CROSSWISE CUTS

摘要

FIELD: mining.;SUBSTANCE: rock massif is disintegrated in crosswise direction by heading-and-winning machine planetary-disc actuators It is performed by serial intersecting cuts in radial-tangential and tangential-radial directions made by cutters of disc running in opposite directions. Said discs are set at the angle to plane formed by cutter lengthwise axis and radial direction relative thereto.;EFFECT: decreased working forces of hearing and wining machine.;2 cl, 3 dwg
