Abstract

Based on the theoretical and experimental research, the authors solve the problem connected with the aggravating effect exerted by blasting in an open pit mine on an underground mine under the pit bottom in hybrid mining operations when carried out in the same vertical plane. The problem solution is the borehole charge design having a decreased seismic effect. The situation becomes much complicated when mining is performed under conditions of blastinginduced rockburst hazard. In this case, it is of the top priority to detect beforehand and register the initial stage of hazardous events. The article proves experimentally the usability of the rockburst hazard indicator represented by the increase in the number of submicron particles in rocks with the growth of the dynamic loading.
The studies have been supported by the Russian Science Foundation, Project No. 16-17-00066.
