DYNAMIC PLOUGH OF POWERED SUPPORT FOR EXCAVATION OF KIMBERLITE ORE

摘要

FIELD: excavation of mineral resources. SUBSTANCE: dynamic plough of powered support is intended for excavation of kimberlite ore and other mineral resources with large spalling. Dynamic plough includes frame, mechanism moving powered support over sections gear to load and transport ore. At least two hydraulic hammers with energy of singular impulsive force not less than 1000.0 J with individual wedge tools are made fast to frame, are interconnected in parallel and linked to water supply unit. Each hydraulic hammer has built-in member that starts functioning at 50-75% load. Angle of attack of edge of wedge tool amounts to 31-35% to plane of face along travel of plough. Distance between wedge tools should not exceed three widths of their edges. EFFECT: diminished breaking of crystals. 5 dwga
