OPENING AND PROCESSING TECHNOLOGY OF STEEPLY DEEPING VEIN DEPOSIT ОN THE HIGHLANDS

Abstract

Technical and technological solutions on the development, preparation and mining extraction
providing efficient and safety mining of the
Kvaisinsky polymetallic deposit are worked out.
Technical and economic comparison of the patterns of deposit’s lower levels resources development is performed. It is determined that development with a motor transport grade from a running
adit is more efficient by discounted expenditures
than development by a new adit. Нigh efficiency of
subsurface ore mining is attained by introduction
the technology of ore caving and self-propelled
equipment employment with low expenditures.
