Abstract

The results of the experimental research into processes that take place during differently directed controlled trajectory blasting of ore and rock in underground mining of flat-dipping lodes are presented. It is found that methods for designing blast patterns should take into account both linear concentration of energy and dynamics of the increase in resistance to throw of rocks and ore in a narrow stoping area. Based on the modeling data, the throw coefficient and blasting front advance are plotted as functions of geometrical and energy characteristics of the model. It is shown that blasting and throw of ore in the stoping zone is accompanied with the effect of additional fragmentation of ore due to collision with the stope roof.
