Determination of the suitable height at sublevel – caving methods

Abstract

The paper in a short form deals with theoretical aspects of the sublevel-caving methods on iron deposits Nižná Slaná and Kobeliarovo. This mining method in a stope-block use the LHD system mechanization by the all underground caving stoping technology. By mining is a big problem the determination of height at one sublevel in the alternation siderit lens. They are use a numerical methods of the determinatoin.
