摘要：

The highlight of the paper is the potentiality of resource conservation and mitigation of ecological impact after blasting at open pit mines by application of the forced convection of detonation products in a hole, It is expounded how to drive the forced convection of gas-dispersion detonation products, as well as a convector and the designs of various charges to be used in the open pit mining are described. The prime elements of the turboblasting technology are described, and its case history is presented, backed by the actual data on the existent resource-saving and nature-oriented pay-off of the technology application at ore and nonmetallic quarries and coal open pits in Russia.
