AN ANOTHER WAY FOR OPEN PIT MINE DESIGN OPTIMIZATION – FLOATING SLOPES METHOD

Abstract

Authors of the work presents main principles of a new method of design the ultimate pit which is primarily applicable for bedded formations, but also can be acceptable for other types of deposits. On the basis of main criteria of optimum design (profitability and slope stability), the authors have tested theirs procedure and proposed a new method for optimum design of open pit mines, for which the most suitable name would be the Floating Slopes Method.
