Abstract
Изобретение относитс к добыче природного камн , в частности к выполнению замкнутого горизонтального пропила при проходке пионерных траншей. Цель - повышение эффективности способа за счет снижени энергоемкости процесса резки при одновременном снижении потерь камн . Способ включает выполнение вертикальной щели 1, ширина которой обеспечивает прохождение приводного вала 2 дл выполнени горизонтального пропила. Затем осуществл ют горизонтальный замкнутый пропил 4 дисковой пилой (ДП) 3. Вертикальную щель 1 прорезают ниже зоны работы горизонтальной ДП 3 на величину H≥B.D/B (β-1), где D - диаметр ДП дл выполнени горизонтального пропила, B - ширина пропила, B - ширина вертикальной щели, β - коэффициентт разбухани штыба. Штыб 5 собираетс в нижней части вертикальной щели 1, тем самым предотвраща заштыбовку и заклинивание ДП 3. 1 ил.The invention relates to the extraction of natural stone, in particular to the implementation of a closed horizontal kerf while sinking pioneer trenches. The goal is to increase the efficiency of the method by reducing the energy intensity of the cutting process while reducing stone losses. The method includes making a vertical slit 1, the width of which allows the drive shaft 2 to pass to perform a horizontal kerf. Then, horizontal closed sawing 4 is carried out with a circular saw (BF) 3. Vertical slot 1 is cut below the working zone of horizontal BF 3 by the value of H≥B . D / B (β-1), where D is the diameter of the DP to perform horizontal cutting, B is the width of the cutting, B is the width of the vertical slit, β is the coefficient of swelling of the tip. Pin 5 is assembled in the lower part of the vertical slot 1, thereby preventing the pinning and jamming of PD 3. 1 sludge.
