Effect of stemming on rock breaking with explosion of a cylindrical charge

  • Rock Breaking

Journal of Mining Science Aims and scope

Abstract

A calculation scheme is developed for the destroying action of explosion of a borehole charge in a brittle medium taking account of the ejection of stemming material and outflow of detonation product gases. The influence of different rock and explosive parameters on the efficiency of stemming application is studied.
