Concept Paper on Decline Ramp Opening in Deep Horizons XIth to XIIIth, of the Mine Trepca in Stanterg

Abstract

The paper focuses on a study to find out the expenses and time duration of opening of deep horizonts XIth - XIIth in Trepça mine with decline shaft (ramp) and is giving the result which can be recommended in practice and bring benefit to the mine.Although this subject was not treated so far, in practice of underground mines in Kosovo, by scientific thematic methods of opening optimization and comparison of this method especially in a case when is imposed the hoisting method in the mine since current method cannot be used further because of limits that hoist machine has. Depending of that, it will depend shorter time of investment return and favorable production, that can have decisively impact on the mine economy.In this paper were analysed and compared essential points, expenses parameters starting from needed labor force, expenses and time for opening main objects, the underground water drainage problems, needed analytical and statistical calculations.
