Abstract

The article presents a brief review on the subject of
contour blasting. Development of pretreatment Meliorativny in underground conditions. This method
is to create a directional gap of the pattern along the
relevant project lines. Typically, it uses a number of
closely spaced borehole charges explode simultaneously. The result is a surface of discontinuity, which
prevents the flow of the ox-new processes and, therefore, is a kind of screen that protects the array from
the impact resistance of nearby explosions.
