Abstract

In modern technology of explosive stripping at carrying out of mining excavations the more and more application are parallel cuttings, the principle of work of which consists that at explosion of borehole charges there is destruction of a rock cofferdam between the charged boreholes and an idle borehole, as a result of what is formed a cuttings cylindrical cavity of the greater depth.
