Abstract: The analysis of the effectiveness of drilling and blasting operations in the capital and preparatory you-the wages, the investigations about 100 passports BSB, used over the past 20 years in the mountains-tion of coal mines and ore mines of Kuzbass and 80 passports BSB used in various mountains-nodobyvajushchij basins of Russia and abroad. Based on the studies it is concluded that the choice of the scheme is determined not only ha the character of a blast hole location of the EXPLOSIVE charge relative to the plane of the face, the direction of crack vitasti or strata of rocks and other geometric factors, but mainly by providing conditions for the work of blasting charges for breaking rocks and full release, shattered rock mass formed from the cut cavity. The classification of explosive methods of forming cutters of the cavity in the construction of the research Institute of the mine workings, which can serve as a basis for choosing a specific design of the groove, providing the required indicators of the excavation works, depending on the specific circumstances of the excavation: mining and geological conditions; the depth of the blasting; the type of drilling equipment; cross-section generation and appointment; qualifications drifters.
