Abstract:Purpose is to determine a function of the reduced expenditures connected with drilling-and-blasting operations, loading and hauling operations, and rock fragmentation depending upon the cost of machine-shift of the applied facility, its operation modes, hardness of rock being blasted, cost of the used explosive, and rock fragmentation quality based upon the developed optimization mathematical model. Methods. Method of statistical evaluation of natural blockiness structure of the rock as well as quality … Show more
“…Moreover, it is critically important for the environmental and ecological sustainability of mineral resources mining [6]- [8]. The main objective of new technological solutions should be in the provision of sustainable development of a mining region both in terms of ecology and economy by involving greater volumes of the associate raw materials being today the mineral industry wastes [9]- [12]. However, in case of building industry those wastes can be a source of material production.…”
