Разработан методический подход к оптимизации стоимости вскрышных работ в зависимости от гранулометрического состава взорванной горной массы. Предложена укрупненная методика оценки удельных затрат на вскрышные работы, обоснованы принципы факторной зависимости гранулометрического состава взорванной горной массы и стоимости проведения горных работ; выполнены апробация методики на основе экспериментальных данных, полученных в результате серии взрывов в условиях золоторудного карьера, и верификация полученных расчетных значений путем сопоставления удельных затрат методом укрупненного счета и прямых экономических расчетов; доказана валидность предложенного методического подхода на основе учета параметров удельной стоимости эксплуатации и производительности оборудования на вскрышных работах. Результаты исследования могут быть использованы в инженерных изысканиях при обосновании параметров проекта буровзрывных работ с учетом технологических особенностей горнотранспортного комплекса.
