ABSTRACT
/Full article available only in Bulgarian language/

Expenses for maintenance of mine roads at any moment depend on volumes of
road surface, needed for laying at the same moment, to transform roads into a usable
condition. A method is presented for their quantitative determination toward a series
of consecutive moments and principles of statistical modeling are applied for
determining the regularities of change of expenses with the time.

Key words: mine roads, exploitation expenses, methods for statistical modeling
