Effect of physical and mechanical properties rock mass jointing on parameters of explosion funnel formed during breakage of exposed plane

, : Effect of physical and mechanical properties rock mass jointing on parameters of explosion funnel formed during breakage of exposed plane. Fiziko-Tehnicheskiye Problemy Razrabotki Poleznykh Iskopayemykh 1997(4): 59-61

The investigation data on structural slackening factor determination for conditions of explosion destruction of jointing rock mass are presented. For calculation of this factor a jointing rate is appropriate to determine in dependence of a distance between fractures and calculated explosion funnel radius, obtained for breaking conditions in a monolith.
