Development of Design and Technological Parameters of Ore Extraction for Underground Mining

Abstract

While defining rational constructive and technological underground mining technique parameters we should consider many factors, especially in caving methods. The experience of exploiting caving technologies shows that the use of traditional designs of this technique is not always efficient and economically expedient. The article presents alternative caving methods, developed by specialists of the department for "Geotechnologies of mineral resources development" of the Moscow Mining Institute, for the conditions of Kola Peninsula polymetallic deposits, chromite deposits of Western Kazakhstan. What is more, we proposed the vector of caving systems development in the deep and high stress mining with difficult geomechanical conditions.
