ABSTRACT: The research data on up-dating of drilling-and-blasting operations at the Tey quarry are presented. The process for trim blasting to edge pit walls and to cave blocks is proposed, the formed benches being of greater height. The blasting and delay interval patterns s developed allow that the convergence factor is increased from 1.4 to 3.2, while the oversize yield is lowered by 10–15%.

PHYSICAL MODELING OF EXPLOSIVE FRACTURING OF PRE-STRESSED ROCKS

Volchenko G. N. and Seryakov V. M.*

Siberian State Industrial University, Novokuznetsk, Russia
* Institute of Mining, Siberian Branch, Russian Academy of Sciences, Novosibirsk, Russia

ABSTRACT: The authors lay out experimental data on the technology for block fracturing by the short-delay blasting, which induces the formation of rock-weakening cavities of a curved shape. The cavity formation makes it possible to create tensile stresses in a rock block and to reduce the power-intensity of the blasting fracturing.

Institute of Mining, Siberian Branch, Russian Academy of Sciences, Novosibirsk, Russia
* Siberian State Industrial University, Novokuznetsk, Russia

ABSTRACT: The authors perform the theoretical and experimental modeling of schemes for short-delay blasting of rock blocks with formation of free, curved surfaces. It is established that tension areas arising within a rock block at all breakage stages tend to reduce the energy intensity of the block fracturing.
