Model for optimizing mechanical and chemical leaching mode

Abstract

Гірничий вісник, вип. 102, 2017 11 and bench groups along the V-shaped trench line under construction considering the seismic impact of mass blasting (see table 1, option 2).The obtained results showed the stability degree the mine workings correspond to standard indices (the calculated value of the stability factor (SF) is within 1,31-2,34).Conclusions. Thus, the proposed method for calculating the stability of open pits, considering the seismic impact of mass blasting, allows to determine numerical values of drilling and blasting parameters, the use of which when designing the spiral extended V-shaped trench in the eastern wall area of the "YuGOK" open pit allowed the construction of the trench in conditions of the limited working area and secured long-term and safe operation.
