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.
